Abstract
STUDY QUESTION What is the risk of an undetected natural conception pregnancy during luteal phase ovarian stimulation, and how does it impact the pregnancy's course? SUMMARY ANSWER The risk for an undetected, natural conception pregnancy in luteal phase ovarian stimulation is low and it appears that ovarian stimulation is unlikely to harm the pregnancy. WHAT IS KNOWN ALREADY Random start ovarian stimulation appears to be similarly effective as early follicular stimulation start; and it allows ovarian stimulation to be started independent of the cycle day and throughout the cycle, in accordance with the patients' and clinics' schedule as long as there is no intention of a fresh embryo transfer in the same cycle. Starting ovarian stimulation in the luteal phase bears the possibility of an-at the timepoint of stimulation start-undetected, natural conception pregnancy that has already occurred. There is scarce data on the incidence of this event as well as on the possible implications of ovarian stimulation on the course of an existing pregnancy. STUDY DESIGN, SIZE, DURATION This retrospective observational study, performed between June 2017 and January 2024, analyzed luteal phase stimulations, in which a natural conception pregnancy was detected during the ovarian stimulation treatment for IVF/ICSI. Luteal phase stimulation was defined as ovarian stimulation started after ovulation and before the next expected menstrual bleeding, with a serum progesterone (P4) level of >1.5 ng/ml on the day of stimulation start or 1 day before. PARTICIPANTS/MATERIALS, SETTING, METHODS Women who underwent a luteal phase ovarian stimulation in a tertiary referral ART center. MAIN RESULTS AND THE ROLE OF CHANCE A total of 488 luteal phase stimulation cycles were included in the analysis. Luteal phase stimulation was only started after a negative serum hCG measurement on the day or 1 day before commencement of ovarian stimulation. Ten patients (2.1%) had an undetected natural conception pregnancy at the time of luteal phase stimulation start. Eight of these patients underwent an ovarian stimulation in a GnRH-antagonist protocol and two in a progestin-primed stimulation protocol (PPOS). Recombinant FSH was used as stimulation medication for all patients, the patients with a PPOS protocol received additional recombinant LH. One pregnancy (0.2%) was detected after the oocyte retrieval, the other nine pregnancies were detected either due to persistent high serum progesterone levels or due to an increasing progesterone level after an initial decrease before oocyte retrieval. In the cycles with an undetected natural conception pregnancy, the median number of stimulation days was 8 days (range: 6-11 days) and median serum hCG at detection of pregnancy was 59 IU hCG (range: 14.91-183.1). From 10 patients with a pregnancy, three patients delivered a healthy baby, two patients had ongoing pregnancies at the time of summarizing the data, three patients had biochemical pregnancies (patient age: 30, 39, and 42 years), one patient had an ectopic pregnancy which required a salpingectomy, and one patient (age: 34 years) had an early pregnancy loss. LIMITATIONS, REASONS FOR CAUTION The retrospective study design and the small sample size can limit the accuracy of the estimates. WIDER IMPLICATIONS OF THE FINDINGS Overall, there is a small risk of undetected natural conception pregnancies when luteal phase stimulation is undertaken. It appears that there are no adverse effects through either direct effect on the embryo or indirectly through a detrimental effect on the corpus luteum function on the pregnancy in our cohort. STUDY FUNDING/COMPETING INTEREST(S) This study did not receive funding. The authors declare that there is no conflict of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
This study intended to investigate if gynecological cancers compromise ovarian function and reduce the success of assisted reproduction techniques (ART). No clinical and molecular data together is available on this issue for gynecological or other organ cancers. Steroidogenic pathways and DNA damage response characteristics of the granulosa cells retrieved from the 39 gynecological cancer patients were analyzed together with their clinical ART characteristics in comparison to 31 control ART patients. Patients with gynecological malignancies were similar to the control IVF patients for the number of mature oocytes retrieved, fertilization rates and embryo development competency. Molecular analyses of the granulosa cells retrieved from these cancer patients did not detect any perturbations in gonadotropin receptor expression and response, sex steroid production, cholesterol utilization/storage and, DNA damage response pattern in comparison to control IVF patients without cancer. This study provides the first reassuring clinical and molecular combined data set that the presence of gynecological malignancy does not appear to have any detrimental effect on clinical IVF cycle characteristics and ovarian functioning at molecular level.

Abstract
PURPOSE OF REVIEW Identify the most recent and significant evidence regarding the ovulation trigger within the framework of a multicycle approach through DuoStim, providing valuable insights for improving treatment strategies in patients with a poor prognosis. RECENT FINDINGS The trigger method plays a pivotal role in optimizing in-vitro fertilization (IVF) stimulation, influencing oocyte retrieval and maturation rates, as well as follicle recruitment in consecutive ovarian stimulations such as double stimulation. Decision-making involves multiple factors and, while guidelines exist for conventional stimulation, specific recommendations for the multicycle approach are not well established. SUMMARY The different methods for inducing oocyte maturation underscore the need for personalization of IVF protocols. The GnRH agonist trigger induces rapid luteolysis and establishes favorable hormonal conditions that do not adversely affect the recruitment of consecutive follicular waves in the context of DuoStim. It serves as a valid alternative to hCG in freeze-all cycles. This strategy might enhance the safety and flexibility of ovarian stimulations with no impact on oocyte competence and IVF efficacy.

Abstract
OBJECTIVES To compare the pregnant outcomes of luteal phase progestin-primed ovarian stimulation (PPOS) protocol with clomiphene citrate supplementation (LPPOS+CC) and follicular phase PPOS+CC protocol (FPPOS+CC) in young women with diminished ovarian reserve (DOR). METHODS A total of 483 women aged ≤35 years with DOR, who underwent in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)/embryo transfer (ET) with controlled ovarian stimulation using LPPOS+CC (n=257) or FPPOS+CC (n=226) protocols during June 2018 and December 2021 at the First Affiliated Hospital of Wenzhou Medical University, were included in this retrospective study. The baseline characteristics, ovarian stimulation, endocrinological indicators, clinical outcomes between the two groups, and pregnancy outcomes of women achieved at least one high-quality cleavage-stage embryo or good-morphology blastocyst between the two groups were compared. RESULTS No statistically significant differences were identified between the groups with respect to number of oocytes retrieved, oocyte maturation rate, high-quality cleavage-stage embryo cycle rate, the percentage of women with profound pituitary suppression, preterm birth rate, and live birth rate (P>0.05). Compared to FPPOS+CC group, the duration of stimulation [11.0 (9.0,12.0) vs. 9.0 (8.0,11.0) d, P<0.01] was significantly longer in the LPPOS+CC group. The LH levels on the day of trigger [4.0 (2.7,5.3) vs. 5.1 (3.2,7.2) IU/L, P<0.01], the percentage of women with LH levels of >10 IU/L on the trigger day (3.13% vs. 10.67%, P<0.01), and the two pronucleate (2PN) rate of ICSI oocytes (72.16% vs. 79.56%, P<0.05) were significantly lower in the LPPOS+CC group than those in the FPPOS+CC group. The consumption of total gonadotropin [2213 (1650,2700) vs. 2000 (1575,2325) IU, P<0.01], the progesterone levels on the day of trigger [1.3 (0.8,2.9) vs. 0.9 (0.6,1.2) ng/mL, P<0.01], the clinical pregnancy rate [61.88% vs. 46.84%, P<0.01], and implantation rate [42.20% vs. 31.07%, P<0.01] in the LPPOS+CC group were significantly higher than those in the FPPOS+CC group. CONCLUSIONS Compared to FPPOS+CC, the LPPOS+CC protocol appears to have better pregnancy outcomes for young women with DOR undergoing IVF-ICSI-ET.

Does dual oocyte retrieval with continuous FSH administration increase the number of mature oocytes in low responders? An open-label randomized controlled trial. Hum Reprod 2024; 39:538-547. [PMID: 38199789 DOI: 10.1093/humrep/dead276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 11/21/2023] [Indexed: 01/12/2024] Open
Abstract
STUDY QUESTION Is there an increase in the total number of metaphase II (MII) oocytes between a conventional ovarian stimulation (OS) and a double uninterrupted stimulation? SUMMARY ANSWER There is no increase in the total number of MII oocytes when comparing one conventional OS to a continuous stimulation with double oocyte aspiration. WHAT IS KNOWN ALREADY Based on the concept of multiple follicular waves, the combination of two stimulations in the same ovarian cycle has gained interest in patients with a low ovarian reserve. This so-called dual stimulation approach is usually characterized by a discontinuation of FSH administration for ∼5 days and appears to have a favourable impact on the number of retrieved oocytes without affecting the embryo quality or ploidy status. The outcomes of dual uninterrupted OS have not yet been studied. STUDY DESIGN, SIZE, DURATION This was an open-label randomized controlled trial (RCT) with superiority design, performed in a single tertiary centre. Subjects were randomized with a 1:1 allocation into two groups between October 2019 and September 2021. All patients underwent a conventional stimulation with recombinant FSH. When two or more follicles of 17 mm were present, the final inclusion criterion was assessed; randomization occurred only in the presence of ≤9 follicles of ≥11 mm. In Group A, ovulation was triggered with hCG, and oocyte retrieval (OR) was performed 34-36 h later, followed by a fresh single or double embryo transfer (SET or DET) on Day 3/5. In Group B, ovulation was triggered with GnRH agonist, followed by another OS, without discontinuation of the FSH administration. In the presence of one or more follicles of ≥17 mm, the second stimulation was completed with hCG. A freeze-all strategy (Day 3/5) was applied for both retrievals, followed by transfer of one or two embryos in an artificially prepared frozen-thawed cycle. In the absence of one or more follicles of ≥17 mm after 13 additional days of stimulation, the second cycle was cancelled. All ORs were executed by a senior fertility specialist who was blinded for the first treatment, and all follicles >10 mm were aspirated, according to routine clinical practice. The primary outcome was the total number of MII oocytes. Patients were followed up until all embryos were transferred, or until live birth was achieved. Other secondary outcomes included the number of cumulus-oocyte complexes (COCs), the number of good quality embryos (Day 3/5), the ongoing pregnancy rate, and gonadotropin consumption. PARTICIPANTS/MATERIALS, SETTING, METHODS Patients between 25 and 40 years old, with an anti-Müllerian hormone level of ≤1.5 ng/ml, antral follicle count of ≤6, or ≤5 oocytes after a previous stimulation, were included. At the start, 70 patients were eligible for participation in the trial, of whom 48 patients fulfilled the final inclusion criterium and were randomized. After drop-out of two patients, 23 patients were randomized to a single round of OS (Group A), and 23 patients were randomized to two uninterrupted rounds of OS (Group B). MAIN RESULTS AND THE ROLE OF CHANCE Baseline characteristics were similar between both groups. The cumulative number of COCs and MII oocytes after completion of the second OR was similar in Group A and Group B [5.3 ± 2.7 versus 5.3 ± 3.0 (P = 0.95); 4.1 ± 2.4 versus 4.3 ± 2.7 (P = 0.77)]. Likewise, a comparable number of excellent and good quality embryos was available on Day 3 (3.0 ± 2.0 versus 2.7 ± 2.0; P = 0.63). In Group B, the cancellation rate due to insufficient response to the second round of stimulation was 39.1% (9/23). When focusing on the first stimulation in both groups, there were no significant differences regarding basal FSH, gonadotropin consumption, and the number of preovulatory follicles. After the first OR, the mean number of COC and MII oocytes was significantly higher in Group A (who had hCG triggering), compared to Group B (who had GnRH agonist triggering) [5.3 ± 2.7 versus 3.3 ± 2.2; difference 95% CI (0.54 to 3.45), P = 0.004 and 4.1 ± 2.4 versus 3.0 ± 2.2; difference 95% CI (-0.15 to 2.6), P = 0.05, respectively]. Likewise, the number of excellent and good quality embryos on Day 3 was significantly higher (3.0 ± 2.0 versus 1.9 ± 1.7; P = 0.02) in Group A. LIMITATIONS, REASONS FOR CAUTION This study was powered to demonstrate superiority for the number of MII oocytes after dual stimulation. Investigating the impact of dual stimulation on pregnancy rates would have required a larger sample size. Furthermore, the heterogeneity in embryo vitrification and transfer policies precluded a correct comparison of embryologic outcomes between both groups. WIDER IMPLICATIONS OF THE FINDINGS This is the first RCT investigating the role of continuous stimulation with double aspiration in low responders. Our results show no statistically significant differences in the cumulative number of MII oocytes between one conventional stimulation with fresh ET and two consecutive stimulations with a freeze-only approach. Furthermore, the observed suboptimal oocyte yield after agonist ovulation triggering in low responders in the dual uninterrupted OS group is a reason for concern and further scrutiny, given that previous RCTs have shown similar outcomes in normal and high responders after hCG and GnRH agonist triggers.

Abstract
BACKGROUND In the last decade, luteal-phase ovarian stimulation (LPOS) has been suggested as an alternative controlled ovarian stimulation (COS) protocol for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles mainly in women with a history of poor ovarian response (POR). The present randomized controlled trial study aimed to compare the outcomes of follicular phase ovarian stimulation (FPOS) and LPOS protocols in POR cases undergoing ICSI cycles. METHODS Seventy-eight POR patients who met the Bologna criteria and underwent an ICSI cycle were included. In this study, 39 POR cases were allocated to the FPOS group, and 39 POR cases were allocated to the LPOS group. The primary outcome was the number of metaphase II (MII) oocytes. In addition, the total number of oocytes, number of top-quality day 3 embryo, day 3 embryo development rate, chemical pregnancy and clinical pregnancy rates were defined as secondary outcomes. RESULTS The obtained results demonstrated that the number of MII oocytes significantly increased in the LPOS group compared to the FPOS group (P = 0.007). However, there was no significant difference between the two groups regarding the number of GV and MI oocytes, number of top-quality day 3 embryos and day 3 embryo development rate among both categories of patients. Also, the number of total and MII oocytes was significantly higher in the LPOS group (P = 0.016). CONCLUSION These results suggest that LPOS protocol effectively increases the number of mature oocytes in women with a history of POR.

J Ovarian Res 2024; 17:1. [PMID: 38169411 PMCID: PMC10759700 DOI: 10.1186/s13048-023-01323-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 12/10/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND An unexpected impaired ovarian response pertains to an insufficient reaction to controlled ovarian hyperstimulation. This deficient reaction is identified by a reduced count of mature follicles and retrieved oocytes during an IVF cycle, potentially diminishing the likelihood of a successful pregnancy. This research seeks to examine whether the characteristics of antral follicles can serve as predictive indicators for the unexpected impaired ovarian response to controlled ovarian stimulation (COS). METHODS This retrospective cohort study was conducted at a tertiary university hospital. The electronic database of the ART (assisted reproductive technologies) center was screened between the years 2012-2022. Infertile women under 35 years, with normal ovarian reserve [anti-Müllerian hormone (AMH) > 1.2 ng/ml, antral follicle count (AFC) > 5] who underwent their first controlled ovarian stimulation (COS) cycle were selected. Women with < 9 oocytes retrieved (group 1 of the Poseidon classification) constituted the group A, whereas those with ≥ 9 oocytes severed as control (normo-responders) one (group B). Demographic, anthropometric and hormonal variables together with COS parameters of the two groups were compared. RESULTS The number of patients with < 9 oocytes (group A) was 404, and those with ≥ 9 oocytes were 602 (group B). The mean age of the group A was significantly higher (30.1 + 2.9 vs. 29.4 + 2.9, p = 0.01). Group A displayed lower AMH and AFC [with interquartile ranges (IQR); AMH 1.6 ng/ml (1-2.6) vs. 3.5 ng/ml (2.2-5.4) p < 0.01, AFC 8 (6-12) vs. 12 (9-17), p < 0.01]. The number of small antral follicles (2-5 mm) of the group A was significantly lower [6 (4-8) vs. 8 (6-12) p < 0.01), while the larger follicles (5-10 mm) remained similar [3 (1-5) vs. 3(1-6) p = 0.3] between the groups. CONCLUSION The propensity of low ovarian reserve and higher age are the main risk factors for the impaired ovarian response. The proportion of the small antral follicles may be a predictive factor for ovarian response to prevent unexpected poor results.

Conventional follicular-phase ovarian stimulation vs. luteal-phase stimulation in suboptimal responders: a randomized controlled trial. F S Rep 2023; 4:344-352. [PMID: 38204945 PMCID: PMC10774905 DOI: 10.1016/j.xfre.2023.07.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 07/20/2023] [Accepted: 07/24/2023] [Indexed: 01/12/2024] Open
Abstract
Objective To compare the oocyte yield between follicular-phase stimulation (FPS) and luteal-phase stimulation (LPS) in suboptimal responders. Design Prospective, randomized, crossover clinical trial. Patients Forty-one patients with infertility according to the POSEIDON (Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number) criteria (1b/2b). Interventions Crossover study on 2 assigned ovarian stimulations that started randomly in the follicular or luteal phase. The in vitro fertilization cycles were not consecutive but separated in time (45 days to 6 months). The random crossover design ensured that all subjects received the first treatment by chance. Main Outcome Measures The primary objective was the number of cumulus-oocyte complexes retrieved in each cycle. Secondary objectives were number of metaphase II and fertilized oocytes, additional doses of recombinant follicle-stimulating hormone, and the duration of ovarian stimulation (days). Results The mean number of cumulus-oocyte complexes retrieved was similar between the FPS and LPS groups (7.5 ± 4.6 vs. 7.0 ± 4.1; 95% confidence interval [CI] for the mean, 5.8-8.7 vs. 5.6-8.3, respectively; the difference between means, -0.5; 95% CI, -1.8 to +1.5). Similarly, the mean number of metaphase II oocytes retrieved was not different between the FPS and LPS groups (5.4 ± 3.6 vs. 5.2 ± 2.8; 95% CI for the mean, 4.2-6.5 vs. 4.3-6.1, respectively; the difference between means, -0.2; 95% CI, -1.2 to +1.1). Moreover, the secondary objectives were similar between FPS and LPS groups. Conclusions In this study, the oocyte yield in LPS did not increase in suboptimal responders compared with that in FPS when the onset of LPS was separated in time from FPS.

Abstract
OBJECTIVE To compare the clinical outcomes and cost-effectiveness of progestin-primed ovarian stimulation (PPOS) and the gonadotropin-releasing hormone-antagonist (GnRH-A) protocol in fertility preservation (FP) in cancer patients. The stimulation option when patients were in the luteal phase was also explored. METHODS This retrospective study analyzed clinical data from 163 patients who underwent FP. The number of retrieved oocytes and vitrified oocytes/embryos, total dose of gonadotropin, duration of stimulation, number of injections, and cost were compared among the PPOS, GnRH-A, and luteal phase stimulation (LPS) groups. RESULTS No significant differences were noted in the numbers of retrieved oocytes and vitrified oocytes/embryos among the three groups. In the multiple regression model, age (P = 0.02) and antral follicle count (AFC) (P < 0.001), but not the controlled ovarian stimulation (COS) protocols (P = 0.586), were associated with the number of retrieved oocytes. The number of injections and the cost were all significantly lower in the PPOS and LPS groups than in the GnRH-A group(P < 0.001). CONCLUSION PPOS had similar clinical results but was superior medically and economically to GnRH-A. For patients in the luteal phase, LPS was an optional protocol with similar outcomes and costs to PPOS.

Abstract
Ovarian stimulation for assisted reproductive technology is traditionally started in the early follicular phase. The essential rationale is to allow timely follicle growth and oocyte retrieval to ensure synchronization of the in-vitro cultured embryos with the receptive period of the endometrium in a fresh transfer cycle. In addition, conventional thought suggested that follicle recruitment happened only once, around menstruation. A deeper understanding of folliculogenesis, advances in cryobiology and an increasing proportion of freeze-all cycles provide a unique opportunity here. Experience from oncofertility patients as well as infertile women and oocyte donors who underwent ovarian stimulation in different phases of the menstrual cycle, dubbed 'random start' cycles, suggests that the number of oocytes collected and their reproductive potential do not depend on the time of starting ovarian stimulation, although the duration of stimulation and gonadotrophin consumption can vary slightly. It may be time to free both patients and clinics from the obsession with starting ovarian stimulation in the early follicular phase in planned freeze-all cycles. The flexibility provided by random start cycles is one aspect of individualizing treatment to patients' needs.

Opening the black box: why do euploid blastocysts fail to implant? A systematic review and meta-analysis. Hum Reprod Update 2023; 29:570-633. [PMID: 37192834 DOI: 10.1093/humupd/dmad010] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 03/22/2023] [Indexed: 05/18/2023] Open
Abstract
BACKGROUND A normal chromosomal constitution defined through PGT-A assessing all chromosomes on trophectoderm (TE) biopsies represents the strongest predictor of embryo implantation. Yet, its positive predictive value is not higher than 50-60%. This gap of knowledge on the causes of euploid blastocysts' reproductive failure is known as 'the black box of implantation'. OBJECTIVE AND RATIONALE Several embryonic, maternal, paternal, clinical, and IVF laboratory features were scrutinized for their putative association with reproductive success or implantation failure of euploid blastocysts. SEARCH METHODS A systematic bibliographical search was conducted without temporal limits up to August 2021. The keywords were '(blastocyst OR day5 embryo OR day6 embryo OR day7 embryo) AND (euploid OR chromosomally normal OR preimplantation genetic testing) AND (implantation OR implantation failure OR miscarriage OR abortion OR live birth OR biochemical pregnancy OR recurrent implantation failure)'. Overall, 1608 items were identified and screened. We included all prospective or retrospective clinical studies and randomized-controlled-trials (RCTs) that assessed any feature associated with live-birth rates (LBR) and/or miscarriage rates (MR) among non-mosaic euploid blastocyst transfer after TE biopsy and PGT-A. In total, 41 reviews and 372 papers were selected, clustered according to a common focus, and thoroughly reviewed. The PRISMA guideline was followed, the PICO model was adopted, and ROBINS-I and ROB 2.0 scoring were used to assess putative bias. Bias across studies regarding the LBR was also assessed using visual inspection of funnel plots and the trim and fill method. Categorical data were combined with a pooled-OR. The random-effect model was used to conduct the meta-analysis. Between-study heterogeneity was addressed using I2. Whenever not suitable for the meta-analysis, the included studies were simply described for their results. The study protocol was registered at http://www.crd.york.ac.uk/PROSPERO/ (registration number CRD42021275329). OUTCOMES We included 372 original papers (335 retrospective studies, 30 prospective studies and 7 RCTs) and 41 reviews. However, most of the studies were retrospective, or characterized by small sample sizes, thus prone to bias, which reduces the quality of the evidence to low or very low. Reduced inner cell mass (7 studies, OR: 0.37, 95% CI: 0.27-0.52, I2 = 53%), or TE quality (9 studies, OR: 0.53, 95% CI: 0.43-0.67, I2 = 70%), overall blastocyst quality worse than Gardner's BB-grade (8 studies, OR: 0.40, 95% CI: 0.24-0.67, I2 = 83%), developmental delay (18 studies, OR: 0.56, 95% CI: 0.49-0.63, I2 = 47%), and (by qualitative analysis) some morphodynamic abnormalities pinpointed through time-lapse microscopy (abnormal cleavage patterns, spontaneous blastocyst collapse, longer time of morula formation I, time of blastulation (tB), and duration of blastulation) were all associated with poorer reproductive outcomes. Slightly lower LBR, even in the context of PGT-A, was reported among women ≥38 years (7 studies, OR: 0.87, 95% CI: 0.75-1.00, I2 = 31%), while obesity was associated with both lower LBR (2 studies, OR: 0.66, 95% CI: 0.55-0.79, I2 = 0%) and higher MR (2 studies, OR: 1.8, 95% CI: 1.08-2.99, I2 = 52%). The experience of previous repeated implantation failures (RIF) was also associated with lower LBR (3 studies, OR: 0.72, 95% CI: 0.55-0.93, I2 = 0%). By qualitative analysis, among hormonal assessments, only abnormal progesterone levels prior to transfer were associated with LBR and MR after PGT-A. Among the clinical protocols used, vitrified-warmed embryo transfer was more effective than fresh transfer (2 studies, OR: 1.56, 95% CI: 1.05-2.33, I2 = 23%) after PGT-A. Lastly, multiple vitrification-warming cycles (2 studies, OR: 0.41, 95% CI: 0.22-0.77, I2 = 50%) or (by qualitative analysis) a high number of cells biopsied may slightly reduce the LBR, while simultaneous zona-pellucida opening and TE biopsy allowed better results than the Day 3 hatching-based protocol (3 studies, OR: 1.41, 95% CI: 1.18-1.69, I2 = 0%). WIDER IMPLICATIONS Embryo selection aims at shortening the time-to-pregnancy, while minimizing the reproductive risks. Knowing which features are associated with the reproductive competence of euploid blastocysts is therefore critical to define, implement, and validate safer and more efficient clinical workflows. Future research should be directed towards: (i) systematic investigations of the mechanisms involved in reproductive aging beyond de novo chromosomal abnormalities, and how lifestyle and nutrition may accelerate or exacerbate their consequences; (ii) improved evaluation of the uterine and blastocyst-endometrial dialogue, both of which represent black boxes themselves; (iii) standardization/automation of embryo assessment and IVF protocols; (iv) additional invasive or preferably non-invasive tools for embryo selection. Only by filling these gaps we may finally crack the riddle behind 'the black box of implantation'.

Abstract
STUDY QUESTION Can anti-Müllerian hormone (AMH) help predict how many oocytes will be retrieved following double stimulation (DuoStim)? SUMMARY ANSWER A simple clinical tool can use serum AMH values to predict ovarian response following DuoStim in IVF cycles. WHAT IS ALREADY KNOWN The knowledge that multiple follicular waves arise during a single ovarian cycle has led to the introduction of unconventional ovarian stimulation protocols. The DuoStim protocol involves two successive ovarian stimulations performed during a single ovarian cycle and has been proposed as an approach for patients with poor ovarian response and for medical fertility preservation. As AMH has been used as a marker of ovarian reserve and stimulation response, the current study aimed to investigate the diagnostic performance of AMH in predicting the number of retrieved oocytes following DuoStim. STUDY DESIGN, SIZE, DURATION This is a retrospective observational study involving 116 patients who received IVF treatment from January 2021 to September 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS The study was conducted at a private IVF centre. Only patients who had their AMH measured prior to treatment and had complete patient records regarding their clinical and IVF/ICSI cycle characteristics were included. The primary outcome was the correlation between AMH values and the number of oocytes retrieved following DuoStim. Parametric and non-parametric tests were used to compare baseline characteristics and outcomes. Spearman's R was used to analyse correlations between variables, while the C statistic was used to calculate the diagnostic performance of AMH. MAIN RESULTS AND THE ROLE OF CHANCE AMH levels were significantly correlated with the total number of oocytes retrieved after the DuoStim (R 0.61; CI 0.44-0.70; P < 0.0001). The difference in the total number of oocytes retrieved between the first (median 4 oocytes, interquartile range (IQR) 2-6) and second (median 6 oocytes, IQR 3.2-8) stimulation was statistically significant (P < 0.0001). However, there was no significant difference in the number of mature oocytes that were retrieved (median of 3 and 4 in the first and second stimulations, respectively). After the first stimulation, 68% of patients had at least one blastocyst available, while after the second stimulation, 74% did (NS). Based on linear regression, each 0.25 ng/ml increase in basal AMH corresponds to one additional oocyte recovered at the end of both stimulations (R2: 0.32, P < 0.0001). LIMITATIONS, REASONS FOR CAUTION The results are limited owing to the observational nature of the study and the number of participants. WIDER IMPLICATIONS OF THE FINDINGS Counselling infertile couples regarding the intermediate outcome of IVF (i.e. number of retrieved oocytes) is one of the most demanding tasks that clinicians face. To our knowledge, this is the first study that provides an easy-to-use clinical tool that enables the quantitative prediction of ovarian response following DuoStim, based on serum AMH values.

Abstract
PURPOSE Random start protocols are commonly used for oocyte cryopreservation in women with cancer. However, albeit generally reassuring, available evidence is still insufficient to rule out a sub-optimal cycle outcome. This study aimed to compare follicular steroidogenesis between women initiating the random start protocol in the luteal phase and those initiating in the follicular phase. METHODS Consecutive women with cancer scheduled for oocyte cryostorage were prospectively recruited. We excluded those requiring a concomitant letrozole assumption. All women received a standardized protocol with recombinant FSH and GnRH antagonists. At the time of oocyte retrieval, follicular fluids were pooled, and a sample was collected and frozen at -80 °C. All samples were assayed concomitantly after thawing by liquid chromatography-tandem mass spectrometry. The concentration of 15 different steroid hormones was determined. RESULTS Seventy-one women were recruited. Thirty-three initiated the ovarian stimulation in the luteal phase, while the remaining 38 initiated in the follicular phase. Baseline characteristics were generally similar. Cycle outcome did also not differ; the median (interquartile range) number of frozen mature oocytes was 9 (5-14) and 10 (5-21), respectively (p = 0.42). None of the 15 tested steroid hormones differed. CONCLUSIONS The endocrine microenvironment surrounding oocytes is not markedly influenced by the phase of the menstrual cycle at the initiation of ovarian stimulation. This result further supports the validity of random start protocols.

Abstract
Background Double ovarian stimulation is one of the most used strategies in poor-prognosis patients. There is a high heterogeneity between the studies regarding the execution of this stimulation protocol. The aim of this study was to investigate whether the day on which luteal phase stimulation begins after the first oocyte retrieval affects ovarian response in DuoStim cycles. Methods This observational and retrospective study included 541 DuoStim cycles between January 2018 and December 2021 in a private fertility clinic. Patients were assigned to 4 groups according to the timing of the onset of luteal phase stimulation after oocyte retrieval (0-2nd day, 3rd day, 4th day and 5th-6th day). The primary outcome was the number of oocytes retrieved in the luteal phase in each group. Results No differences were found between groups in the number of oocytes collected (5.12 ± 3.56 vs. 5.39 ± 3.74 vs. 5.61 ± 3.94 vs. 5.89 ± 3.92; p=0,6), MII or number of follicles. An increase in the duration of stimulation was found when stimulation started on the 4th day (10.42 ± 2.31 vs. 10.68 ± 2.37 vs. 11.27 ± 2.40 vs. 10.65 ± 2.37 days, p=0,033). A lower number of fertilized oocytes was observed when stimulation began before the fourth day (3.36 ± 2.80 vs. 3.95 ± 2.53 vs. 4.03 ± 2.73 vs. 4.48 ± 3.11; p=0,036). The number of blastocysts was higher when the stimulation started 5-6 days after retrieval (1.82 ± 1.74 vs. 2.13 ± 1.61 vs. 2.33 ± 2.06 vs. 2.91 ± 2.39; p= 0,030). Discussion The number of oocytes retrieved does not differ depending on the day that stimulation begins. However, oocytes competence in terms of fertilized oocytes and blastulation, appears to be lower when the second stimulation starts before the fourth day after oocyte retrieval.

Luteal Phase Stimulation in the Same Cycle Is an Effective Strategy to Rescue POSEIDON Poor Responders with No Embryos after the First Follicular Stimulation. J Hum Reprod Sci 2023; 16:218-226. [PMID: 38045502 PMCID: PMC10688278 DOI: 10.4103/jhrs.jhrs_76_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 08/06/2023] [Accepted: 08/21/2023] [Indexed: 12/05/2023] Open
Abstract
Background Poor responders may benefit from recruiting a 'second wave' of antral follicles within the same cycle. This concept forms the basis of double stimulation which has been named as 'DuoStim'. This protocol involves ovarian stimulation in both follicular and luteal phases with egg retrieval in each phase, respectively, to increase the number of oocytes and embryos in one menstrual cycle. This can be considered a potentially valuable option for women with poor ovarian reserve/response to maximise the number of oocytes retrieved in a single ovarian cycle in the shortest possible time. Aims The aim of this study was to evaluate the efficacy of the DuoStim protocol in women classified as POSEIDON poor responders undergoing in vitro fertilization by comparing the embryological outcomes between the follicular and luteal phase stimulations in the same menstrual cycle. Settings and Design This was a retrospective cohort study of 131 patients who enrolled to undergo DuoStim cycles from January 2021 to Sept. 2022, at a IVF center in a tertiary care hospital. Materials and Methods The follicular phase stimulation used a standard antagonist protocol for the first oocyte retrieval. Thereafter, the luteal phase stimulation was started 3 days after the first retrieval, with the same dose of gonadotropin along with a daily 10 mg medroxyprogesterone acetate tablet, followed by a second oocyte retrieval. Blastocysts produced in both the phases were subsequently vitrified. Statistical Analysis Used The paired t-test was used for comparing means and 95% confidence intervals (CIs) for different parameters. McNemar's test was used to compare paired proportions. The analysis was conducted using R statistical environment 4.2. Results The mean number of oocytes retrieved and the mean number of utilizable blastocysts frozen per stimulation cycle were found to be significantly higher in the luteal phase as compared to the follicular phase (5.71 ± 3.95 vs. 4.87 ± 2.79, P = 0.02, and 1.43 ± 1.22 vs. 0.95 ± 1, P = 0.001, respectively). However, the mean fertilization rate and the mean blastocyst utilization rate were found to be similar between both the phases. The length of stimulation was found to be approximately 3 days longer in the luteal phase (12.63 ± 2.43 vs. 9.75 ± 1.85, P = 0.001). Overall, the odds of obtaining a usable blastocyst in the luteal phase was found to be significantly higher than in the paired follicular phase (73.9% vs. 57.7%, P = 0.012, odds ratio: 2.286 [95% CI: 1.186-4.636]). Also importantly, the luteal phase stimulation was able to rescue 68% (32/47) of patients where no blastocysts were formed in the follicular phase. Conclusion Our data demonstrate that in women with poor reserve, the addition of luteal stimulation could increase the chances of achieving a pregnancy by significantly increasing the number of eggs and transferable embryos per menstrual cycle compared to follicular stimulation alone. Furthermore, luteal phase stimulation in the same cycle proved to be an effective strategy to rescue POSEIDON poor responders with no embryos after the first stimulation.

Abstract
PURPOSE OF REVIEW The technical improvements in IVF allowed the implementation of nonconventional ovarian stimulation protocols for some specific patients. Where time is crucial, such as with oncologic patients, poor-prognosis patients, patients with low ovarian reserve, and those with advanced maternal age, access to IVF treatment is even more critical. Some of these protocols might start in the late follicular phase, luteal phase, or involve both stimulations within the same ovarian cycle. RECENT FINDINGS Until now, published evidence showed that oocytes retrieved from unconventional protocol seem to be developmentally, genetically, and reproductively competent. Second stimulation in the same ovarian cycle after the conventional approach may represent a sound alternative to oocyte accumulation. This can be proposed in progress after careful counselling focused on the patients' chances of finding at least one euploid embryo on account of their age and of the number of blastocysts obtained after the conventional approach. SUMMARY The adoption of these new strategies, known as double stimulation protocol, can be conceived as a real full-personalization of ovarian stimulation. Multicentre prospective RCTs are urgently needed to evaluate the efficacy, efficiency, and costs of double stimulation versus two consecutive conventional approaches with standard or mild stimulation and in a different IVF setting.

Abstract
Double ovarian stimulation (DuoStim), initially only suggested for fertility preservation in cancer patients, is now increasingly also used in routine clinical IVF, especially in poor responders. The claimed rational for this is the alleged existence of multiple follicular waves in a single intermenstrual interval, allowing for retrieval of more oocytes in a single IVF cycle. This commentary argues that this expansion of purpose lacks rationale, evidence, and follow-up. Consequently, we suggest that, unless valid clinical indications have been established, DuoStim be only subject of controlled clinical trials with appropriate experimental consents.

Abstract
Many studies have sought to explore the impact of high-dose gonadotropin on stimulation outcomes based on a hypothesis that higher doses of follicle-stimulating hormone may harm the quantity or quality of oocytes and, therefore, be counterproductive. Herein, we describe the results of a narrative review aimed at elucidating any harm associated with "excess" follicle-stimulating hormone dosing in poor-to-moderate responders. Additionally, we sought to describe the outcomes associated with mild ovarian stimulation, with an eye toward determining whether this approach is superior. We concluded that there is no apparent harm to higher-dose gonadotropin stimulation for poor-to-moderate responders. Simultaneously, we did not find compelling data to suggest that mild stimulation is superior. Finally, we close by presenting data that suggest that more gonadotropin may be beneficial in specific clinical scenarios.

Abstract
The aim of this study was to provide an update on ovarian function and the mechanisms of gonadal damage after exposure to chemotherapy in breast cancer survivors. The alkylating agents are toxic to both primordial and growing follicles. However, anti-metabolite drugs are more likely to destroy preantral and antral follicles. Younger patients are more likely to have a higher ovarian reserve, and therefore, more likely to retain some residual ovarian function after exposure to gonadotoxic regimens. However, there can be significant variability in ovarian reserve among patients of the same age. Furthermore, patients with critically diminished ovarian reserve may continue to menstruate regularly. Therefore age and menstrual status are not reliable indicators of good ovarian reserve and might give a false sense of security and result in an adverse outcome if the patient is consulted without considering more reliable quantitative markers of ovarian reserve (antral follicle count and anti-Müllerian hormone) and fertility preservation is not pursued. In contrast to well-documented ovarian toxicity of older chemotherapy regimens, data for newer taxane-containing protocols have only accumulated in the last decade and data are still very limited regarding the impact of targeted therapies on ovarian function.

Abstract
STUDY QUESTION Are the IVF parameters and the steroidogenic luteal characteristics of random-start IVF cycles different from conventional cycles in cancer patients? SUMMARY ANSWER No; controlled ovarian stimulation cycles randomly started at late follicular phase (LFP) and luteal phase (LP) are totally comparable to those conventional IVF cycles started at early follicular phase (EFP) in terms of the expression of the enzymes involved in cholesterol utilization and steroid hormone biosynthesis pathways, gonadotropin receptor expression and, estradiol (E2) and progesterone (P4) production in addition to the similarities in ovarian response to gonadotropin stimulation, oocyte yield, fertilization rate and embryo development competency in cancer patients. WHAT IS KNOWN ALREADY Random start ovarian stimulation protocols are commonly employed for oocyte and embryo freezing for fertility preservation in cancer patients with time constraints who do not have sufficient time to undergo ovarian stimulation initiated conventionally at EFP of the next cycle. No data is available regarding the molecular steroidogenic features of these cycles analyzed together with the clinical IVF characteristics in cancer patients. We aimed to address this question in this study to help understand how similar the random start cycles are to the conventional start ones. STUDY DESIGN, SIZE, DURATION A clinical translational research study conducted in 62 cancer patients undergoing IVF for fertility preservation between the years 2017 and 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS Sixty-two patients who were diagnosed with different types of cancer and underwent ovarian stimulation for oocyte (n = 41) and embryo (n = 21) cryopreservation using GnRH antagonist protocol and human menopausal gonadotropins before receiving cancer treatment/surgery were enrolled in the study. For patients with breast cancer and endometrial cancer the aromatase inhibitor letrozole was used with gonadotropin stimulation. Ovarian stimulation was initiated conventionally at EFP in 22 patients and served as control while it was started at LFP in 20, and mid-LP in the other 20 patients. The luteinized granulosa cells (GCs) were recovered from follicular aspirates during oocyte retrieval procedure and used for the experiments separately for each individual patient. The expression of the enzymes involved in sex steroid biosynthesis (StAR, 3β-HSD, Aromatase) and cholesterol synthesis (3-hydroxy 3-methylglutaryl Co-A reductase (HMG-Co-A reductase)), utilization (hormone sensitive lipase (HSL)), and storage (Acetyl-Coenzyme A acetyltransferase 1 (ACAT-1)), and gonadotropin receptor expression status were analyzed using immunoblotting and RT-PCR methods. Laser confocal immunofluorescence imaging was applied to analyze and compare the expression patterns of the steroidogenic enzymes and their relation with mitochondria. In vitro E2 and P4 production by the cells were compared among the groups. MAIN RESULTS AND THE ROLE OF CHANCE Baseline demographic and IVF characteristics of the patients undergoing the conventional start and random start IVF cycles were similar. Duration of gonadotropin stimulation was significantly longer in LFP and LP start cycles in comparison to the conventional ones. Ovarian response to gonadotropin stimulation, mature and total oocyte yield, fertilization and Day 5 blastulation rates of the embryos were comparable between the conventional versus random start cycles. When the luteal GCs of these random start cycles were analyzed we could not find any gross differences between these cycles in terms of the viability index and gross light microscopic morphologic features. More detailed analysis of the molecular luteal characteristics of the cells using RT-PCR, immunoblotting methods revealed that the expression profiles of the gonadotropin receptors, and the enzymes involved in sex steroid biosynthesis and cholesterol synthesis/utilization, and the steroidogenic activity of the luteal GCs of the random start cycles are almost identical to those of the conventional start cycles. Confocal image analysis demonstrated similar patterns in the signal expression profiles of the steroidogenic enzymes and their co-localization within mitochondria. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION Caution should be exercised when interpreting our data and counseling cancer patients seeking fertility preservation because it is still unclear if previous exposure to cancer drugs, different ovarian pathologies or infertility etiologies, previous ovarian surgery and/or any other underlying diseases that are concomitantly present with cancer may cause a difference between conventional and random start stimulation protocols in terms of IVF parameters, luteal function and reproductive outcome. Relatively low number of patients in each stimulation protocol and pooling of luteal GCs for each patient rather than individual analysis of each follicle and oocyte are additional limitations of our study. WIDER IMPLICATIONS OF THE FINDINGS Our findings provide reassurance that random start protocol offers cancer patients an equally good prospect of fertility preservation as conventional IVF.

Abstract
PURPOSE An impact of different gonadotrophins selection for ovarian stimulation (OS) on oocyte competence has yet to be defined. In this study, we asked whether an association exists between OS protocol and euploid blastocyst rate (EBR) per metaphase-II (MII) oocytes. METHODS Cycles of first preimplantation genetic testing for aneuploidies conducted by women ≥ 35 years old with their own metaphase-II oocytes inseminated in the absence of severe male factor (years 2014-2018) were clustered based on whether recombinant FSH (rec-FSH) or human menopausal gonadotrophin (HMG) was used for OS, then matched for the number of fresh inseminated eggs. Four groups were outlined: rec-FSH (N = 57), rec-FSH plus rec-LH (N = 55), rec-FSH plus HMG (N = 112), and HMG-only (N = 127). Intracytoplasmic sperm injection, continuous blastocyst culture, comprehensive chromosome testing to assess full-chromosome non-mosaic aneuploidies and vitrified-warmed euploid single embryo transfers (SETs) were performed. The primary outcome was the EBR per cohort of MII oocytes. The secondary outcome was the live birth rate (LBR) per first SETs. RESULTS Rec-FSH protocol was shorter and characterized by lower total gonadotrophin (Gn) dose. The linear regression model adjusted for maternal age showed no association between the Gn adopted for OS and EBR per cohort of MII oocytes. Similarly, no association was reported with the LBR per first SETs, even when adjusting for blastocyst quality and day of full blastulation. CONCLUSION In view of enhanced personalization in OS, clinicians shall focus on different endpoints or quantitative effects related to Gn action towards follicle recruitment, development, and atresia. Here, LH and/or hCG was administered exclusively to women with expected sub/poor response; therefore, we cannot exclude that specific Gn formulations may impact patient prognosis in other populations.

Abstract
AIM To provide practice guidelines about fertility preservation (FP) in oncology. METHODS We selected 400 articles after a PubMed review of the literature (1987-2019). RECOMMENDATIONS Any child, adolescent and adult of reproductive age should be informed about the risk of treatment gonadotoxicity. In women, systematically proposed FP counselling between 15 and 38 years of age in case of treatment including bifunctional alkylating agents, above 6 g/m2 cyclophosphamide equivalent dose (CED), and for radiation doses on the ovaries ≥3 Gy. For postmenarchal patients, oocyte cryopreservation after ovarian stimulation is the first-line FP technique. Ovarian tissue cryopreservation should be discussed as a first-line approach in case of treatment with a high gonadotoxic risk, when chemotherapy has already started and in urgent cases. Ovarian transposition is to be discussed prior to pelvic radiotherapy involving a high risk of premature ovarian failure. For prepubertal girls, ovarian tissue cryopreservation should be proposed in the case of treatment with a high gonadotoxic risk. In pubertal males, sperm cryopreservation must be systematically offered to any male who is to undergo cancer treatment, regardless of toxicity. Testicular tissue cryopreservation must be proposed in males unable to cryopreserve sperm who are to undergo a treatment with intermediate or severe risk of gonadotoxicity. In prepubertal boys, testicular tissue preservation is: - recommended for chemotherapy with a CED ≥7500 mg/m2 or radiotherapy ≥3 Gy on both testicles. - proposed for chemotherapy with a CED ≥5.000 mg/m2 or radiotherapy ≥2 Gy. If several possible strategies, the ultimate choice is made by the patient.

Abstract
Random start protocols are commonly used for oocytes cryopreservation in women with cancer. However, evidence to support their effectiveness is yet modest. This study aims to compare the quality of ovarian response between the ovary carrying the dominant follicle or the corpus luteum (active ovary) and the contralateral ovary (resting ovary). Women with a diagnosis of malignancy who underwent oocytes cryopreservation were reviewed. The main inclusion criterion was the presence of a unilateral dominant follicle or a unilateral corpus luteum on the first day of ovarian hyperstimulation. The primary outcome was the number of mature oocytes retrieved. Intra-patient comparisons between the two ovaries were made using the nonparametric Wilcoxon test for paired data. Forty-three women were included. The number of mature oocytes retrieved from the active and the resting ovaries did not differ, the median [interquartile range-IQR] being 4 [2-7] and 5 [2-8], respectively (p = 0.09). The rate [IQR] of mature oocytes per developed follicle was 58% [40-80%] and 65% [33-87%], respectively (p = 0.42). In addition, no significant difference emerged when repeating the analyses separately for women carrying dominant follicles and for those carrying corpora lutea. This study failed to detect any detrimental effect of the presence of a dominant follicle or a corpus luteus on the ovarian response to hyperstimulation, thus supporting the validity of random start protocols.

Second stimulation in the same ovarian cycle: an option to fully-personalize the treatment in poor prognosis patients undergoing PGT-A. J Assist Reprod Genet 2022; 39:663-673. [PMID: 35128583 PMCID: PMC8995212 DOI: 10.1007/s10815-022-02409-z] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 01/17/2022] [Indexed: 10/19/2022] Open
Abstract
PURPOSE Our primary objective was to assess whether immediately undergoing a second stimulation in the same ovarian cycle (DuoStim) for advanced-maternal-age and/or poor-ovarian-reserve (AMA/POR) patients obtaining ≤ 3 blastocysts for preimplantation-genetic-testing-for-aneuploidies (PGT-A) is more efficient than the conventional-approach. METHODS All AMA/POR patients obtaining ≤ 3 blastocysts after conventional-stimulation between 2017 and 2019 were proposed DuoStim, and 143 couples accepted (DuoStim-group) and were matched for the main confounders to 143 couples who did not accept (conventional-group). GnRH-antagonist protocol with recombinant-gonadotrophins and agonist trigger, intra-cytoplasmatic-sperm-injection (ICSI) with ejaculated sperm, PGT-A and vitrified-warmed euploid single-blastocyst-transfer(s) were performed. The primary outcome was the cumulative-live-birth-delivery-rate per intention-to-treat (CLBdR per ITT) within 1 year. If not delivering, the conventional-group had 1 year to undergo another conventional-stimulation. A cost-effectiveness analysis was also conducted. RESULTS The CLBdR was 10.5% in the conventional-group after the first attempt. Only 12 of the 128 non-pregnant patients returned (165 ± 95 days later; drop-out = 116/128,90.6%), and 3 delivered. Thus, the 1-year CLBdR was 12.6% (N = 18/143). In the DuoStim-group, the CLBdR was 24.5% (N = 35/143; p = 0.01), 2 women delivered twice and 13 patients have other euploid blastocysts after a LB (0 and 2 in the conventional-group). DuoStim resulted in an incremental-cost-effectiveness-ratio of 23,303€. DuoStim was costlier and more effective in 98.7% of the 1000 pseudo-replicates generated through bootstrapping, and the cost-effectiveness acceptability curves unveiled that DuoStim would be more cost-effective than the conventional-approach at a willingness-to-pay threshold of 23,100€. CONCLUSIONS During PGT-A treatments in AMA/POR women, DuoStim can be suggested in progress to rescue poor blastocyst yields after conventional-stimulation. It might indeed prevent drop-out or further aging between attempts.

Abstract
OBJECTIVE In this study, we aimed to compare the efficacy of luteal phase stimulation (LPS) and follicular phase stimulation (FPS) in two separate menstrual cycles (2-5 months intervals) of the same patient, utilizing LPS with dydrogesteron only. METHODS This retrospective case control study was conducted with patients with diminished ovarian reserve (DOR) (Group 1) and infertile patients with Anti-Müllerian hormone >1.2 ng/mL (Group 2) undergoing two ovarian stimulations (FPS and LPS with dydrogesteron only) and two oocyte retrievals in two separate menstrual cycles (2-5 months intervals) in the Division of Reproductive Endocrinology and Infertility of Baskent University, Ankara, between April 2019 and December 2019. RESULTS In group 1, the number of frozen embryos was significantly higher in LPS when compared to FPS; 1.71 vs. 0.54, (p < .001), respectively. In group 2, the number of frozen embryos was higher in LPS when compared to FPS (0.8 vs. 0.4) however the difference did not reach a statistical significance (p: 0.157). CONCLUSION LPS may be beneficial especially in the patients with diminished ovarian reserve with follicular asynchronization in the menstrual onset. In addition, it should be kept in mind that dydrogesterone only may be used instead of gonadotropin-releasing hormone antagonist to prevent possible luteinizing hormone rise in LPS.

Abstract
Antral follicle growth and recruitment are the basis of female reproduction. Follicular wave theory explains the recruitment, growth, and selection of antral follicles. This article is devoted to the follicular wave pattern in female reproduction throughout life. We highlight progress in understanding the rhythmic follicle changes based on clinical studies and studies on animal models. We review the follicular wave pattern before puberty, during pregnancy, and in perimenopause. Several mathematical models are known which quite accurately describe follicular wave dynamics. The follicular waves theory allows the implementation of the new approaches to ovarian stimulation. Stimulation in the luteal phase and double stimulation are used more widely nowadays for fertility preservation in cancer patients and for increasing the chances of IVF programs success in poor responder patients.

Abstract
Recent advances in our recognition of two to three follicular waves of development in a single menstrual cycle has challenged the dogmatic approach of ovarian stimulation for in vitro fertilization starting in the early follicular phase. First shown in veterinary medicine and thereafter in women, luteal phase stimulation–derived oocytes are at least as competent as those retrieved following follicular phase stimulation. Poor ovarian responders still remain a challenge for many decades simply because they do not respond to ovarian stimulation. Performing follicular phase stimulation and luteal phase stimulation in the same menstrual cycle, named as double stimulation/dual stimulation, clearly increases the number of oocytes, which is a robust surrogate marker of live birth rate in in vitro fertilization across all female ages. Of interest, apart from one study, the bulk of evidence reports significantly higher number of oocytes following luteal phase stimulation when compared with follicular phase stimulation; hence, performing double stimulation/dual stimulation doubles the number of oocytes leading to a marked decrease in patient drop-out rate which is one of the major factors limiting cumulative live birth rates in such poor prognosis patients. The limited data with double stimulation/dual stimulation-derived embryos is reassuring for obstetric and neonatal outcome. The mandatory requirement of freeze-all and lack of cost-effectiveness data are limitations of this novel approach. Double stimulation/dual stimulation is an effective strategy when the need to obtain oocytes is urgent, including patients with malignant diseases undergoing oocyte cryopreservation and patients of advanced maternal age or with reduced ovarian reserve.

Abstract
INTRODUCTION Several studies suggest that luteinizing hormone (LH) could improve IVF outcome in women of advanced reproductive age by optimizing androgen production. In this review, we assessed the role of recombinant-human LH (r-hLH) and recombinant human follicle stimulating hormone (r-hFSH) co-treatment in ovarian stimulation for assisted reproductive technology in women of advanced reproductive age candidates for assisted reproduction. MATERIAL AND METHODS Using a preregistered protocol we systematically searched Medline/PubMed, Scopus and the ISI Web of Science databases to identify randomized controlled trials in which r-hFSH monotherapy protocols were compared with r-hFSH/r-hLH co-treatment in women ≥35 years undergoing fresh IVF cycles. We calculated the pooled odds ratio (OR) for dichotomous data and the weight mean difference (WMD) for continuous data with an associated 95% confidence interval (CI). The meta-analyses were conducted using the random-effect model. P values < 0.05 were considered statistically significant. Subgroup analyses of all primary and secondary outcomes were performed only in women aged 35-40 years. RESULTS Twelve studies were identified. In women aged between 35 and 40 years, r-hFSH/r-hLH co-treatment was associated with higher clinical pregnancy rates (OR 1.45, CI 95% 1.05-2.00, I2 = 0%, P = 0.03) and implantation rates (OR 1.49, CI 95% 1.10-2.01, I2 = 13%, P = 0.01) versus r-hFSH monotherapy. Fewer oocytes were retrieved in r-hFSH/r-hLH-treated patients than in r-hFSH-treated patients both in women aged ≥35 years (WMD -0.82 CI 95% -1.40 to - 0.24, I2 = 88%, P = 0.005) and in those aged between 35 and 40 years (WMD -1.03, CI - 1.89 to - 0.17, I2 = 0%, P = 0.02). The number of metaphase II oocytes, miscarriage rates and live birth rates did not differ between the two groups of women overall or in subgroup analysis. CONCLUSION Although more oocytes were retrieved in patients who underwent r-hFSH monotherapy, this meta-analysis suggests that r-hFSH/r-hLH co-treatment improves clinical pregnancy and implantation rates in women between 35 and 40 years of age undergoing ovarian stimulation for assisted reproduction technology. However, more RCTs using narrower age ranges in advanced age women are warranted to corroborate these findings.

Abstract
AIM To evaluate the overall performance and oocyte quality of follicular phase stimulation (FPS) vs. luteal phase stimulation (LPS) among patients undergoing double ovarian stimulation (DuoStim). MATERIALS AND METHODS Observational retrospective two-center cohort study including 79 infertile women who underwent a total of 87 DuoStim cycles between January 2017 and May 2019. Besides assessing baseline characteristics in order to determine the patients' clinical profile, we analyzed the FPS and LPS regarding the total dose of gonadotropin received, the duration of stimulation, the number and maturity of oocytes, fertilization and blastocyst formation rates, and the number of blastocysts obtained. RESULTS The patients' baseline characteristics were compatible with a diminished ovarian reserve and poor reproductive prognosis. While the luteal phase needed longer stimulation (12 days (5-19) vs. 11 (7-16), p < .001) and slightly higher gonadotropin doses (2946 ± 890 IU vs. 2550 ± 970 IU, p < .001), no significant differences were detected in the oocyte maturity, fertilization, and blastocyst formation rates. However, the number of oocytes retrieved (5 (0-16) vs. 4 (0-15), p = .006), mature oocytes (4 (0-15) vs. 3 (0-11), p = .032), and blastocysts obtained (70 vs. 53) were substantially greater after LPS. CONCLUSIONS The DuoStim strategy in poor prognosis patients increases the number of oocytes and blastocysts available. Moreover, the number of oocytes and blastocysts obtained are higher after LPS when compared to FPS. Thus, it should be considered for selected patients in order to not only improve reproductive outcomes but also shorten the time to pregnancy.

Abstract
AIM To compare the outcome of double ovarian stimulation (DOS) with follicular phase ovarian stimulation (FPS) per started cycle in poor ovarian responders (PORs). METHODS A total of 204 PORs who underwent ovulation induction for in vitro fertilization, cryopreservation of all embryos available, and frozen embryo transfer cycle were retrospectively analyzed. Of those, 146 received single FPS, and 58 received DOS. All viable embryos were cryopreserved and subsequently transferred within 1-6 months. RESULTS The number of oocytes collected and the number of mature oocytes per started cycle were higher in the DOS group compared to the FPS group (6.0 ± 1.9 vs. 2.8 ± 1.3 and 4.3 ± 1.3 vs. 2.2 ± 1.2, respectively, p = 0.001). Clinical pregnancy rate and live birth rate per started cycle were also significantly higher in the DOS group than the FPS group (41.4% vs. 16.4% and 36.2% vs. 15.1%, respectively, p < 0.001). The cancellation rate of embryo transfer due to no viable embryo was significantly lower in the DOS group (10.3%) than the FPS group (40.4%) (p = 0.001). In the DOS group, numbers of oocytes (3.2 ± 1.2 vs. 2.7 ± 1.1, p = 0.006), MII oocytes (2.6 ± 1.0 vs. 2.1 ± 0.8, p = 0.001), and cryopreserved blastocysts (1.5 ± 0.8 vs. 1.1 ± 0.7, p = 0.002) were significantly higher in the luteal ovarian stimulation compared to follicular ovarian stimulation. CONCLUSIONS Live birth per started cycle with DOS is superior to FPS in PORs. Luteal phase stimulation contributes to improving pregnancy rates in these patients.

Abstract
STUDY QUESTION Are the reproductive outcomes (clinical, obstetric and perinatal) different between follicular phase stimulation (FPS)- and luteal phase stimulation (LPS)-derived euploid blastocysts? SUMMARY ANSWER No difference was observed between FPS- and LPS-derived euploid blastocysts after vitrified-warmed single embryo transfer (SET). WHAT IS KNOWN ALREADY Technical improvements in IVF allow the implementation non-conventional controlled ovarian stimulation (COS) protocols for oncologic and poor prognosis patients. One of these protocols begins LPS 5 days after FPS is ended (DuoStim). Although, several studies have reported similar embryological outcomes (e.g. fertilization, blastulation, euploidy) between FPS- and LPS-derived cohort of oocytes, information on the reproductive (clinical, obstetric and perinatal) outcomes of LPS-derived blastocysts is limited to small and retrospective studies. STUDY DESIGN, SIZE, DURATION Multicenter study conducted between October 2015 and March 2019 including all vitrified-warmed euploid single blastocyst transfers after DuoStim. Only first transfers of good quality blastocysts (≥BB according to Gardner and Schoolcraft's classification) were included. If euploid blastocysts obtained after both FPS and LPS were available the embryo to transfer was chosen blindly. The primary outcome was the live birth rate (LBR) per vitrified-warmed single euploid blastocyst transfer in the two groups. To achieve 80% power (α = 0.05) to rule-out a 15% difference in the LBR, a total of 366 first transfers were required. Every other clinical, as well as obstetric and perinatal outcomes, were recorded. PARTICIPANTS/MATERIALS, SETTING, METHODS Throughout the study period, 827 patients concluded a DuoStim cycle and among them, 339 did not identify any transferable blastocyst, 145 had an euploid blastocyst after FPS, 186 after LPS and 157 after both FPS and LPS. Fifty transfers of poor quality euploid blastocysts were excluded and 49 patients did not undergo an embryo transfer during the study period. Thus, 389 patients had a vitrified-warmed SET of a good quality euploid blastocyst (182 after FPS and 207 after LPS). For 126 cases (32%) where both FPS- and LPS-derived good quality blastocysts were available, the embryo transferred was chosen blindly with a 'True Random Number Generator' function where '0' stood for FPS-derived euploid blastocysts and '1' for LPS-derived ones (n = 70 and 56, respectively) on the website random.org. All embryos were obtained with the same ovarian stimulation protocol in FPS and LPS (GnRH antagonist protocol with fixed dose of rec-FSH plus rec-LH and GnRH-agonist trigger), culture conditions (continuous culture in a humidified atmosphere with 37°C, 6% CO2 and 5% O2) and laboratory protocols (ICSI, trophectoderm biopsy in Day 5-7 without assisted hatching in Day 3, vitrification and comprehensive chromosome testing). The women whose embryos were included had similar age (FPS: 38.5 ± 3.1 and LPS: 38.5 ± 3.2 years), prevalence of male factor, antral follicle count, basal hormonal characteristics, main cause of infertility and previous reproductive history (i.e. previous live births, miscarriages and implantation failures) whether the embryo came from FPS or LPS. All transfers were conducted after warming in an artificial cycle. The blastocysts transferred after FPS and LPS were similar in terms of day of full-development and morphological quality. MAIN RESULTS AND THE ROLE OF CHANCE The positive pregnancy test rates for FPS- and LPS-derived euploid blastocysts were 57% and 62%, biochemical pregnancy loss rates were 10% and 8%, miscarriage rates were 15% and 14% and LBRs were 44% (n = 80/182, 95% CI 37-51%) and 49% (n = 102/207, 95% CI 42-56%; P = 0.3), respectively. The overall odds ratio for live birth (LPS vs FPS (reference)) adjusted for day of blastocyst development and quality, was 1.3, 95% CI 0.8-2.0, P = 0.2. Among patients with euploid blastocysts obtained following both FPS and LPS, the LBRs were also similar (53% (n = 37/70, 95% CI 41-65%) and 48% (n = 27/56, 95% CI 35-62%) respectively; P = 0.7). Gestational issues were experienced by 7.5% of pregnant women after FPS- and 10% of women following LPS-derived euploid single blastocyst transfer. Perinatal issues were reported in 5% and 0% of the FPS- and LPS-derived newborns, respectively. The gestational weeks and birthweight were similar in the two groups. A 5% pre-term delivery rate was reported in both groups. A low birthweight was registered in 2.5% and 5% of the newborns, while 4% and 7% showed high birthweight, in FPS- and LPS-derived euploid blastocyst, respectively. Encompassing the 81 FPS-derived newborns, a total of 9% were small and 11% large for gestational age. Among the 102 LPS-derived newborns, 8% were small and 6% large for gestational age. No significant difference was reported for all these comparisons. LIMITATIONS, REASONS FOR CAUTION The LPS-derived blastocysts were all obtained after FPS in a DuoStim protocol. Therefore, studies are required with LPS-only, late-FPS and random start approaches. The study is powered to assess differences in the LBR per embryo transfer, therefore obstetric and perinatal outcomes should be considered observational. Although prospective, the study was not registered. WIDER IMPLICATIONS OF THE FINDINGS This study represents a further backing of the safety of non-conventional COS protocols. Therefore, LPS after FPS (DuoStim protocol) is confirmed a feasible and efficient approach also from clinical, obstetric and perinatal perspectives, targeted at patients who need to reach the transfer of an euploid blastocyst in the shortest timeframe possible due to reasons such as cancer, advanced maternal age and/or reduced ovarian reserve and poor ovarian response.

Ovarian follicular waves during the menstrual cycle: physiologic insights into novel approaches for ovarian stimulation. Fertil Steril 2021; 114:443-457. [PMID: 32912608 DOI: 10.1016/j.fertnstert.2020.07.008] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 07/07/2020] [Accepted: 07/07/2020] [Indexed: 12/11/2022]
Abstract
Elucidation of multiple waves of antral ovarian follicular development during the menstrual cycle has challenged traditional concepts of female reproductive physiology and foundations of assisted reproductive therapies. Approximately two-thirds of women develop two follicle waves throughout an interovulatory interval and the remainder exhibit three waves of follicle development. Major and minor waves of follicle development have been observed. Major waves are those in which a dominant follicle develops; dominant follicles either regress or ovulate. In minor waves, physiologic selection of a dominant follicle is not manifest. Knowledge of waves of antral follicular development has led to the global adoption of novel ovarian stimulation strategies in which stimulation can be initiated at various times throughout the cycle. Random-start and luteal-phase ovarian stimulation regimens have had important clinical applications for women requiring urgent oocyte or embryo cryopreservation for fertility preservation prior to chemotherapy. Ovarian stimulation twice in the same cycle, referred to as double stimulation, may be used to optimize clinical outcomes in women with a poor ovarian response to stimulation as well as in those requiring fertility preservation before chemotherapy.

Medroxyprogesterone acetate is a useful alternative to a gonadotropin-releasing hormone antagonist in oocyte donation: a randomized, controlled trial. Fertil Steril 2021; 116:404-412. [PMID: 33814126 DOI: 10.1016/j.fertnstert.2021.02.036] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 02/21/2021] [Accepted: 02/23/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To compare ovarian response and reproductive outcomes in oocyte donors undergoing pituitary suppression with medroxyprogesterone acetate (MPA) versus those undergoing conventional treatment with a gonadotropin-releasing hormone (GnRH) antagonist. DESIGN A prospective, randomized, controlled trial of cycles was conducted from October 2017 to June 2019 to evaluate ovarian response in terms of the number of oocytes. The reproductive outcomes of the recipients were retrospectively analyzed later. SETTING A university-affiliated private in vitro fertilization center. PATIENT(S) We randomly divided 318 donors into 2 groups in a 1:1 ratio. The oocytes obtained were assigned to 364 recipients. One hundred sixty-one donors were treated with a daily dose of 10 mg of MPA administered orally from the beginning of ovarian stimulation (OS), and 156 were treated with a GnRH antagonist (initiated once the leading follicle reached a diameter of 13 mm). Transvaginal ultrasound was performed, and serum estradiol, luteinizing hormone, and progesterone levels were recorded during monitoring. The following additional parameters were analyzed: endocrine profile (in follicular fluid), number of metaphase II oocytes, and pregnancy outcome. INTERVENTION(S) The donors included in the study group were stimulated using recombinant follicle-stimulating hormone and MPA at 10 mg/day, simultaneously begun on cycle day 2 or 3. Ovulation was induced using a GnRH agonist when dominant follicles matured. A short protocol with ganirelix at 0.25 mg/day was used for the control group. Oocytes were assigned to the recipients, followed by routine in vitro fertilization procedures in which 1 embryo was usually transferred. MAIN OUTCOME MEASURE(S) The primary outcome measure was the numbers of oocytes and metaphase II oocytes retrieved. The secondary outcomes were the incidence of premature luteinizing hormone surge, serum and follicular fluid hormone profiles, and clinical pregnancy outcomes in the recipient group. RESULT(S) The number of oocytes retrieved was 21.4 ± 11.7 in the MPA group and 21.2 ± 9.2 in the antagonist group (mean difference 0.14; 95% confidence interval -2.233, 2.517). The total dose of recombinant follicle-stimulating hormone, duration of OS, and endocrine profiles of the serum and follicular fluids were comparable in the 2 groups. No early ovulation was observed in either group. No statistically significant differences with respect to implantation rate (68.1% in the MPA group vs. 62% in the antagonist group), clinical pregnancy rate (64.5% in the MPA group vs. 57.8 in the antagonist group), ongoing pregnancy rate (55.4% in the MPA group vs. 48.5% in the antagonist group), live birth rate (55.1% in the MPA group vs. 48.5% in the antagonist group), or cumulative live birth rate (73.8% in the MPA group vs. 70.7% in the antagonist group) were observed between the groups. CONCLUSION(S) The administration of MPA resulted in oocyte retrieval rates, endocrine profiles, viable embryo numbers, and pregnancy outcomes similar to those achieved with the GnRH antagonist. Therefore, MPA can be recommended for OS in oocyte donation because it permits a more patient-friendly approach. CLINICAL TRIAL REGISTRATION NUMBER NCT03300960.

Ovarian stimulation for fertility preservation in women with cancer: A systematic review and meta-analysis comparing random and conventional starts. J Gynecol Obstet Hum Reprod 2021; 50:102080. [PMID: 33545413 DOI: 10.1016/j.jogoh.2021.102080] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 01/27/2021] [Accepted: 01/28/2021] [Indexed: 12/29/2022]
Abstract
OBJECTIVE In female cancer patients anticipating chemotherapy or radiation, oocyte retrieval for fertility should be performed as efficiently as possible to avoid postponing cancer treatments. Our objective was to compare clinical outcomes among female cancer patients who underwent a conventional early follicular phase-start ovarian stimulation cycle and those who underwent a random-start ovarian stimulation cycle. EVIDENCE REVIEW A systematic review of the literature was performed in accordance with PRISMA guidelines. Medline, Embase.com, Scopus, Cochrane Library, and Clinicaltrials.gov databases were searched to identify all original research published in English through July 2020 on the topic of female cancer patients undergoing ovarian stimulation with a random or conventional start. Studies lacking a comparison group or including women who had already undergone chemotherapy at the time of ovarian stimulation were excluded. The primary author assessed all identified article titles and abstracts, and two independent reviewers assessed full-text articles and extracted data. A meta-analysis with a random-effects model was used to calculate weighted mean differences (WMDs) for outcomes of interest. The primary outcome was the number of mature (meiosis II) oocytes retrieved. Secondary outcomes included duration of stimulation, total dose of gonadotropins, total number of oocytes retrieved, fertilization rate, and number of embryos or zygotes cryopreserved. RESULTS A total of 446 articles were screened, and 9 full-text articles (all retrospective cohort or prospective observational) were included for review. Additionally, pooled primary retrospective data from two institutions were included. In total, data from 10 studies including 1653 women were reviewed. Five studies reported the number of embryos cryopreserved, and four reported fertilization rates. Random-start cycles were slightly longer (WMD 0.57 days, 95 % confidence interval [CI] 0.0-1.14 days) and used more total gonadotropins (WMD 248.8 international units, 95 % CI 57.24-440.40) than conventional-start cycles. However, there were no differences in number of mature oocytes retrieved (WMD 0.41 oocytes, 95 % CI -0.84-1.66), number of total oocytes retrieved (WMD 0.90 oocytes, 95 % CI -0.21-2.02), fertilization rates (WMD -0.12, 95 % CI -1.22-0.98), or number of embryos cryopreserved (WMD 0.12 embryos, 95 %CI -0.98-1.22) between random-start and conventional-start cycles. All outcomes except for the parameter "total oocytes retrieved" yielded an I2 of over 50 %, indicating substantial heterogeneity between studies. CONCLUSION(S) Although random-start cycles may entail a longer duration of stimulation and use more total gonadotropins than conventional-start cycles, the absolute differences are small and likely do not significantly affect treatment costs. The similar numbers of mature oocytes retrieved, fertilization rates, and number of embryos cryopreserved in the two start-types suggest that they do not differ in any clinically important ways. Given that random-start cycles can be initiated quickly, they may help facilitate fertility preservation for cancer patients.

Abstract
Background Double ovarian stimulation (DuoStim) involves two rounds of controlled ovarian stimulation (COS) and oocyte retrieval in immediate succession. It represents a promising approach to increase oocyte yield for patients with diminished ovarian reserve or those with limited time before fertility-threatening oncologic treatment. We report the case of a 31-year-old woman with Stage IC endometrioid ovarian cancer who underwent a triple stimulation or "TriStim," completing three rounds of COS and oocyte retrieval within 42 days prior to bilateral salpingo-oophorectomy. Case presentation A 31 year old nulligravid woman presented for fertility preservation counseling following a bilateral ovarian cystectomy that revealed Stage IC endometroid adenocarcinoma arising within endometrioid borderline tumors. The patient was counseled for bilateral salpingo-oophorectomy, lymph node dissection, and omentectomy followed by three cycles of carboplatin/paclitaxel. Prior to this, all within six weeks, the patient underwent three rounds of controlled ovarian stimulation using an antagonist protocol and human chorionic gonadotropin (hCG) trigger, resulting in vitrification of nine two-pronuclear zygotes (2PN), after which definitive surgery was performed. Conclusions Advantages of DuoStim procedures are increasingly recognized, especially for oncology patients with limited time before potentially sterilizing cancer treatment. To our knowledge, this is the first report of a triple stimulation ("TriStim"). Our case highlights that triple stimulation is a viable option for patients needing urgent fertility preservation in order to maximize egg and embryo yield within a limited time period.

Abstract
When ovarian stimulation is unfeasible, in vitro maturation (IVM) represents an alternative option for fertility preservation (FP). This retrospective study aims to evaluate the feasibility of performing within a short time frame two IVM cycles for FP. Seventeen women with breast cancer, 18-40 years of age, having undergone 2 cycles of IVM followed by oocyte vitrification were included. Non parametric analyses were used. No difference was observed between IVM1 and IVM2 outcomes. No complication was reported. The respective contributions of IVM1 and IVM2 for the number of cryopreserved oocytes were comparable irrespective of the delay between both procedures, even when performed during the same menstrual cycle. Those findings suggest that repeating IVM cycles may constitute a safe option for increasing the number of vitrified mature oocytes for FP. These two retrievals may be performed during the same cycle, providing additional argument for a physiologic continuous recruitment during follicular development.

The best execution of the DuoStim strategy (double stimulation in the follicular and luteal phase of the same ovarian cycle) in patients who are poor ovarian responders. Reprod Biol Endocrinol 2020; 18:102.

Abstract
BACKGROUND Patients found to be poor ovarian responders (POR) are a challenging patient population for any assisted reproduction technology. Despite attempts at various controlled ovarian stimulation schemes, reproductive outcomes in this patient population have not improved. In recent years, the DuoStim protocol (both follicular and luteal phase stimulation during the same menstrual cycle) has shown a potential for use in patients with POR. METHODS This retrospective study reviewed the medical records of 304 women who were diagnosed as POR and underwent the DuoStim protocol. We compared follicular phase stimulation (FPS) data and luteal phase stimulation (LPS) data of the same patients. We also compared the effects of different trigger drugs including urine human chorionic gonadotropin (uHCG; 10,000 IU), recombinant human chorionic gonadotropin (rHCG; 250 μg), and gonadotropin-releasing hormone agonist (GnRH-a; 0.2 mg) at the FPS and LPS stages. RESULTS POR undergoing the DuoStim protocol resulted in a significantly higher number of oocytes retrieved, normal fertilised oocytes, cleaved embryos, cryopreserved embryos, and good quality embryos at the LPS stage than at the FPS stage. Trigger drugs at the FPS stage did not affect the FPS stage data. Regardless of the stage, rHCG and GnRH-a yielded significantly more cryopreserved embryos and good quality embryos than uHCG. CONCLUSION The use of GnRH-a or rHCG as the trigger drug may be better than uHCG in both the FPS and LPS stages for POR undergoing the DuoStim protocol. This will increase the number of good quality embryos at the LPS stage. We found that the LPS stage results in more oocytes (and therefore more embryos) than the FPS stage.

Abstract
Despite the considerate progress to which assisted reproduction technology (ART)
has been subject since 1978, some issues remain unresolved. Notably, the
clinical management of patients with a poor ovarian response is still a
challenge in everyday practice, frustrating to both the patient and the
fertility expert. Poor ovarian responders (PORs) embody 9–24% of patients
undergoing ovarian stimulation, meaning that up to one in four patients conceals
a poor reproductive prognosis. The last decade has witnessed the attempts of the
medical community to standardize diagnosis of POR with the developing of the
Bologna Criteria and the subsequent evolution of the low prognosis patient
elaborated in the POSEIDON classification. The aim of this article is to
summarize all evidence concerning etiology and management of poor ovarian
response, including the most recent advances and future prospects in this
regard.

Effectiveness of the flexible progestin primed ovarian stimulation protocol compared to the flexible GnRH antagonist protocol in women with decreased ovarian reserve. HUM FERTIL 2020; 25:306-312.

Abstract
The aim of this retrospective cohort study was to compare the effectiveness of the new flexible progestin primed ovarian stimulation (fPPOS) protocol with the flexible gonadotropin-releasing-hormone antagonist (GnRH-ant) protocol in women with decreased ovarian reserve (DOR). Twenty-seven women who underwent fPPOS and 54 age-matched women who received GnRH-ant for pituitary suppression were included in the study. All women had DOR and underwent oocyte cryopreservation. Three-hundred IU/day FSH was started on cycle day 2-3 and 0.25 mg/day GnRH-ant or 10 mg/day medroxyprogesterone acetate was started when the leading follicle reached 14 mm or serum oestradiol level was ≥200 ng/mL. The median duration of stimulation, day of commencing pituitary suppression and duration of suppression were similar in both groups, with 8, 5, and 5 days, respectively. The median number of cumulus-oophorous complexes (4.0 vs 5.5), metaphase-two oocytes (3 vs 4), the total number of oocytes cryopreserved (3.0 vs 4.5), and oocyte maturation rates (0.67 vs 0.70) were similar between the fPPOS and GnRH-ant groups, respectively. There was one case of premature ovulation in the fPPOS group and none in the GnRH-ant group (p = 0.91). In conclusion, fPPOS may be used in women with DOR without compromising the number of oocytes retrieved and seems a viable alternative to the flexible GnRH-ant protocol.

Abstract
RESEARCH QUESTION Does double stimulation (DuoStim) affect cumulus cell gene expression in luteal-phase-derived oocytes? DESIGN This prospective observational study included 39 patients with reduced ovarian reserve. Fifteen patients (group 1) underwent IVF with a gonadotrophin-releasing hormone antagonist in the follicular phase and 24 patients (group 2) underwent DuoStim. A total of 149 cumulus cell samples were divided into two groups according to the phase of the cycle: group 1 included 55 follicular-phase-derived oocytes and group 2 included 94 luteal-phase-derived oocytes. The expression levels of the following genes were assessed using quantitative polymerase chain reaction: HAS2, VCAN, ALCAM, PTGS2, GREM1, ITPKA, TRPM7, SDC4, CALM2, SPSB2, TP53I3, PGR and PFKP. RESULTS The expression of 10 out of 13 genes in cumulus cells was similar between DuoStim luteal-phase-derived oocytes and follicular-phase-derived oocytes. A significant increase in the mRNA levels of VCAN (15.542 ± 6.8 versus 20.353 ± 10.58; P = 0.001), SDC4 (1.016 ± 0.65 versus 1.318 ± 0.97; P = 0.013), and TP53I3 (0.185 ± 0.09 versus 0.270 ± 0.11; P = 1.19E-05) was observed in group 2. The number of oocytes collected (5.57 ± 2.3 versus 5.7 ± 2.7; P > 0.05) and the number of blastocysts were comparable between the groups (2.1 ± 2.1 versus 2.7 ± 2.2; P > 0.05). CONCLUSIONS The DuoStim approach leads to changes in the follicular environment. It affects the expression levels of VCAN, SDC4, and TP53I3 in the cumulus cells of luteal-phase-derived oocytes. These results, however, did not correlate with oocyte maturation, embryo quality and pregnancy rate.

Abstract
Recent evidence suggests that follicular development occurs in a wave-like model during the ovarian cycle, where up to three cohorts of follicles are recruited to complete folliculogenesis. This understanding overtakes the previous dogma stating that follicles grow only during the follicular phase of the menstrual cycle. Therefore, in in vitro fertilization (IVF), novel protocols regarding ovarian stimulation have been theorized based on the use of gonadotrophins to prompt the growth of antral follicles at any stage of the menstrual cycle. These unconventional protocols for ovarian stimulation aim at a more efficient management of poor-prognosis patients, otherwise exposed to conflicting outcomes after conventional approaches. DuoStim appears among these unconventional stimulation protocols as one of the most promising. It combines two consecutive stimulations in the follicular and luteal phases of the same ovarian cycle, aimed at increasing the number of oocytes retrieved and embryos produced in the short time-frame. This protocol has been suggested for the treatment of all conditions requiring a maximal and urgent exploitation of the ovarian reserve, such as oncological patients and poor responders at an advanced maternal age. At present, data from independent studies have outlined the consistency and reproducibility of this approach, which might also reduce the drop-out between consecutive failed IVF cycles in poor-prognosis patients. However, the protocol must be standardized, and more robust studies and cost-benefit analyses are needed to highlight the true clinical pros and cons deriving from DuoStim implementation in IVF.

Abstract
In women, the majority of anti-Müllerian hormone (AMH) measured in serum originate from small antral follicles measuring 2-10 mm. In gonadotrophin-stimulated cycles prior to assisted reproductive technology (ART), most of the recruitable follicles develop beyond 10 mm in size and thus lose their AMH secretion capacity causing declining serum AMH levels. The aim of this study was to define the residual serum AMH level after elimination of the AMH producing recruitable follicles following maximal gonadotrophin stimulation. We measured serum AMH and number of follicles according to size at several time points during a cycle of maximal gonadotrophin stimulation (fixed dose of 300 IE HP-hMG) in 107 women with low AMH (median AMH 5 pmol/L, interquartile range (IQR) 3.3-8.3). We found that AMH decreased gradually and reached a minimum level of -55.4% (95% CI -59.6; -50.7) of the baseline value four days after ovulation trigger. Our findings suggest that the residual AMH production origins from pre-antral and small antral follicles not visible by sonography and that they account for up to 40% of the circulating AMH.

Abstract
BACKGROUND In young women with poor ovarian response, luteal-phase ovarian stimulation (LPOS) is a potential method for collecting competent oocytes. The aim of this study was to assess the efficacy of LPOS compared with follicular phase ovarian stimulation (FPOS) in young women with poor ovarian response (POR). METHODS This single-center, prospective, randomized pilot study compared LPOS and FPOS in women with POR fulfilling Bologna criteria who underwent in vitro fertilization at the Instituto Bernabeu. The primary outcome was the number of metaphase II (MII) oocytes obtained by follicular puncture. RESULTS Sixty women were included in the study, with 27 women completing LPOS and 30 undergoing FPOS. There was no statistically significant difference in the number of MII oocytes obtained between the LPOS group and the FPOS group (2.1 ± 2.0 vs. 2.6 ± 2.2, p = 0.31). Length of stimulation was also similar in both groups (8.35 ± 2.8 vs. 8.15 ± 4.1 days, p = 0.69). Similarly, there was no significant difference in the follicle-stimulating hormone total dose, number of cumulus-oocyte complexes, survival rate, fertilization rate, or cancellation rate between groups. A significantly higher Ovarian Sensitivity Index was observed in the LPOS group versus the FPOS group (0.96 vs. 0.57, p = 0.037). CONCLUSION LPOS was comparable with FPOS in terms of efficacy and may improve ovarian responsiveness in young women with POR.

Abstract
Although individualization of ovarian stimulation aims at maximal efficacy and safety in assisted reproductive treatments, in its current form it is far from ideal in achieving the desired success in women with a low prognosis. This could be due a failure to identify such women who are likely to have a low prognosis with currently used prognostic characteristics. Introduction of the patient-oriented strategies encompassing individualized oocyte number (POSEIDON) concept reinforces recognizing such low prognosis groups and stratifying in accordance with important prognostic factors. The POSEIDON concept provides a practical approach to the management of these women and is a useful tool for both counseling and clinical management. In this commentary, we focus on likely management strategies for POSEIDON group 2 criteria.

Abstract
Abstract
BACKGROUND
Freeze-all IVF cycles are becoming increasingly prevalent for a variety of clinical indications. However, the actual treatment objectives and preferred treatment regimens for freeze-all cycles have not been clearly established.
OBJECTIVE AND RATIONALE
We aimed to conduct a systematic review of all aspects of ovarian stimulation for freeze-all cycles.
SEARCH METHODS
A comprehensive search in Medline, Embase and The Cochrane Library was performed. The search strategy included keywords related to freeze-all, cycle segmentation, cumulative live birth rate, preimplantation genetic diagnosis, preimplantation genetic testing for aneuploidy, fertility preservation, oocyte donation and frozen-thawed embryo transfer. We included relevant studies published in English from 2000 to 2018.
OUTCOMES
Our search generated 3292 records. Overall, 69 articles were included in the final review. Good-quality evidence indicates that in freeze-all cycles the cumulative live birth rate increases as the number of oocytes retrieved increases. Although the risk of severe ovarian hyperstimulation syndrome (OHSS) is virtually eliminated in freeze-all cycles, there are certain risks associated with retrieval of large oocyte cohorts. Therefore, ovarian stimulation should be planned to yield between 15 and 20 oocytes. The early follicular phase is currently the preferred starting point for ovarian stimulation, although luteal phase stimulation can be used if necessary. The improved safety associated with the GnRH antagonist regimen makes it the regimen of choice for ovarian stimulation in freeze-all cycles. Ovulation triggering with a GnRH agonist almost completely eliminates the risk of OHSS without affecting oocyte and embryo quality and is therefore the trigger of choice. The addition of low-dose hCG in a dual trigger has been suggested to improve oocyte and embryo quality, but further research in freeze-all cycles is required. Moderate-quality evidence indicates that in freeze-all cycles, a moderate delay of 2–3 days in ovulation triggering may result in the retrieval of an increased number of mature oocytes without impairing the pregnancy rate. There are no high-quality studies evaluating the effects of sustained supraphysiological estradiol (E2) levels on the safety and efficacy of freeze-all cycles. However, no significant adverse effects have been described. There is conflicting evidence regarding the effect of late follicular progesterone elevation in freeze-all cycles.
WIDER IMPLICATIONS
Ovarian stimulation for freeze-all cycles is different in many aspects from conventional stimulation for fresh IVF cycles. Optimisation of ovarian stimulation for freeze-all cycles should result in enhanced treatment safety along with improved cumulative live birth rates and should become the focus of future studies.

Abstract
OBJECTIVE To assess the clinical contribution of luteal-phase stimulation (LPS) to follicular-phase stimulation (FPS) in a single ovarian cycle (DuoStim) for poor responder patients fulfilling the Bologna criteria. DESIGN Observational study (years 2015-2017) including women satisfying ≥2 of the following characteristics: maternal age ≥40 years and/or ≤3 oocytes retrieved after previous conventional stimulation and/or reduced ovarian reserve (i.e., antral follicle count <7 follicles or antimüllerian hormone <1.1 ng/mL). The LPS was started regardless of the outcome of the FPS. SETTING Private in vitro fertilization center. PATIENT(S) A total of 100 of 297 patients fulfilling the Bologna criteria chose to undergo DuoStim. INTERVENTION(S) The FPS and LPS with the same antagonist protocol and agonist trigger, intracytoplasmic sperm injection with ejaculated sperm, preimplantation genetic testing for aneuploidies, and vitrified-warmed euploid single blastocyst transfer. MAIN OUTCOME MEASURE(S) The contribution of LPS to the cumulative live birth rate (CLBR) per intention-to-treat (ITT). RESULT(S) Patients (100) underwent FPS (maternal age, 42.1 ± 1.4 y; previous in vitro fertilization cycles with ≤3 collected oocytes, 0.7 ± 0.9; antral follicle count, 3.8 ± 1.2 follicles; and antimüllerian hormone, 0.56 ± 0.3 ng/mL). Ninety-one patients completed DuoStim. All patients were included in the analysis. More oocytes were obtained after LPS with similar developmental and chromosomal competence as paired FPS-derived ones. The CLBR per ITT increased from 7% after FPS to 15% after DuoStim. Conversely, the CLBR per ITT among the 197 patients that chose a conventional controlled ovarian stimulation strategy was 8%, as only 17 patients who were not pregnant returned for a second stimulation after the first attempt (drop-out rate, 81%). CONCLUSION(S) The LPS-derived oocytes increased the CLBR per ITT in a single ovarian cycle in patients fulfilling the Bologna criteria. The DuoStim strategy is promising to manage this thorny population of patients, especially to avoid discontinuation after a first failed attempt.
