Impact of GnRH antagonist pretreatment on oocyte yield after ovarian stimulation: A retrospective analysis. PLoS One 2024; 19:e0308666. [PMID: 39374231 PMCID: PMC11458021 DOI: 10.1371/journal.pone.0308666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 07/27/2024] [Indexed: 10/09/2024] Open
Abstract
The study investigates whether a 3-day pretreatment course with a GnRH antagonist in the early follicular phase has an impact on the number of retrieved COCs in a GnRH antagonist stimulation protocol. This is a retrospective single center crossover study involving women who did not conceive after one GnRH antagonist stimulation cycle ("standard cycle") and proceeded with another GnRH antagonist stimulation cycle preceded by early administration of GnRH antagonist for 3 days ("pretreatment cycle") with fresh embryo transfer or frozen embryo transfer. 430 patients undergoing 860 cycles were included. The mean female age was 34.4 ± 4.8 years. Indications for fertility treatment included unexplained infertility (34.3%), male-factor infertility (33.3%), age (16.9%), PCOS (8.2%), tubal (4.7) and endometriosis (2.6%). All cycles were divided into two groups: group 1 (standard, 430 cycles) and group 2 (pretreatment, 430 cycles). The mean duration of stimulation was similar in both groups (10.3 vs 10.3 days, p = 0.28). The starting dose of gonadotropin (234.9 vs 196.8 IU, p<0.001), total amount of gonadotropin used (2419 vs 2020 IU, p<0.001), the total number of retrieved COCs (10 vs 7.8 p<0.001) and the number of mature oocytes (8 vs 5.8 p<0.001) were significantly higher in group 2 than in group 1. The Generalized estimating equation (GEE) regression analysis showed that the pretreatment strategy had a significant positive effect on the number of COCs (coefficient 2.4, p <0.001 after adjusting for known confounders (age, indication, stimulation dose, type, and duration of stimulation). In conclusion, A 3-day course of GnRH antagonist pretreatment increases the number of COCs obtained after ovarian stimulation.

Risk factors for poor oocyte yield and oocyte immaturity after GnRH agonist triggering. Hum Reprod 2024; 39:963-973. [PMID: 38452353 DOI: 10.1093/humrep/deae041] [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: 06/21/2023] [Revised: 12/20/2023] [Indexed: 03/09/2024] Open
Abstract
STUDY QUESTION What are the potential risk factors for poor oocyte recuperation rate (ORR) and oocyte immaturity after GnRH agonist (GnRHa) ovulation triggering? SUMMARY ANSWER Lower ovarian reserve and LH levels after GnRHa triggering are risk factors of poor ORR. Higher BMI and anti-Müllerian hormone (AMH) levels are risk factors of poor oocyte maturation rate (OMR). WHAT IS KNOWN ALREADY The use of GnRHa to trigger ovulation is increasing. However, some patients may have a suboptimal response after GnRHa triggering. This suboptimal response can refer to any negative endpoint, such as suboptimal oocyte recovery, oocyte immaturity, or empty follicle syndrome. For some authors, a suboptimal response to GnRHa triggering refers to a suboptimal LH and/or progesterone level following triggering. Several studies have investigated a combination of demographic, clinical, and endocrine characteristics at different stages of the treatment process that may affect the efficacy of the GnRHa trigger and thus be involved in a poor endocrine response or efficiency but no consensus exists. STUDY DESIGN, SIZE, DURATION Bicentric retrospective cohort study between 2015 and 2021 (N = 1747). PARTICIPANTS/MATERIALS, SETTING, METHODS All patients aged 18-43 years who underwent controlled ovarian hyperstimulation and ovulation triggering by GnRHa alone (triptorelin 0.2 mg) for ICSI or oocyte cryopreservation were included. The ORR was defined as the ratio of the total number of retrieved oocytes to the number of follicles >12 mm on the day of triggering. The OMR was defined as the ratio of the number of mature oocytes to the number of retrieved oocytes. A logistic regression model with a backward selection method was used for the analysis of risk factors. Odds ratios (OR) are displayed with their two-sided 95% confidence interval. MAIN RESULTS AND THE ROLE OF CHANCE In the multivariate analysis, initial antral follicular count and LH level 12-h post-triggering were negatively associated with poor ORR (i.e. below the 10th percentile) (OR: 0.61 [95% CI: 0.42-0.88]; P = 0.008 and OR: 0.86 [95% CI: 0.76-0.97]; P = 0.02, respectively). A nonlinear relationship was found between LH level 12-h post-triggering and poor ORR, but no LH threshold was found. A total of 25.3% of patients suffered from oocyte immaturity (i.e. OMR < 75%). In the multivariate analysis, BMI and AMH levels were negatively associated with an OMR < 75% (OR: 4.34 [95% CI: 1.96-9.6]; P < 0.001 and OR: 1.22 [95% CI: 1.03-1.12]; P = 0.015, respectively). Antigonadotrophic pretreatment decreased the risk of OMR < 75% compared to no pretreatment (OR: 0.72 [95% CI: 0.57-0.91]; P = 0.02). LIMITATIONS, REASONS FOR CAUTION Our study is limited by its retrospective design and by the exclusion of patients who had hCG retriggers. However, this occurred in only six cycles. We were also not able to collect information on the duration of pretreatment and the duration of wash out period. WIDER IMPLICATIONS OF THE FINDINGS In clinical practice, to avoid poor ORR, GnRHa trigger alone should not be considered in patients with higher BMI and/or low ovarian reserve, balanced by the risk of ovarian hyperstimulation syndrome. In the case of a low 12-h post-triggering LH level, practicians must be aware of the risk of poor ORR, and hCG retriggering could be considered. STUDY FUNDING/COMPETING INTEREST(S) None. TRIAL REGISTRATION NUMBER N/A.

Fertil Steril 2024; 121:806-813. [PMID: 38253117 DOI: 10.1016/j.fertnstert.2024.01.026] [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: 11/06/2023] [Revised: 01/15/2024] [Accepted: 01/16/2024] [Indexed: 01/24/2024]
Abstract
OBJECTIVE To broadly assess the efficacy of medroxyprogesterone acetate (MPA) for ovulatory suppression during in vitro stimulation compared with gonadotropin-releasing hormone (GnRH) antagonist cycles. DESIGN Cohort trial. SETTING A single academic-affiliated private fertility practice. PATIENTS Patients of all diagnoses aged 18-44 years undergoing autologous in vitro fertilization (IVF) for fertility treatment between 2020 and 2023. INTERVENTIONS Comparison of MPA vs. antagonist IVF stimulation cycles. MAIN OUTCOME MEASURES Rates of premature ovulation, oocyte and embryo yield, embryo quality, pregnancy rates, and logistical benefits. RESULTS Prospective data was collected on 418 patients who underwent MPA protocol ovarian stimulation (MPA group), which was compared with 419 historical control gonadotropin hormone-releasing hormone antagonist cycles (control group). Age was similar between groups (35.6 ± 4.6 vs. 35.7 ± 4.8 years; P = .75). There were no cases of premature ovulation in the MPA group compared with a total of five cases in the control group (0% vs. 1.2%; risk ratio [RR] = 0.09; 95% confidence interval [CI], 0.01, 1.66). No differences were seen between number of oocytes retrieved (14.3 ± 10.2 vs. 14.3 ± 9.7; P = .83), blastocysts (4.9 ± 4.6 vs. 5.0 ± 4.6; P = .89), or euploid blastocysts (2.4 ± 2.6 vs. 2.2 ± 2.4; P = .18) in the MPA vs. control group respectively. Clinical pregnancy rate was similar between groups (70.4% vs. 64.2%; RR = 0.92; 95% CI, 0.72, 1.18). There was no difference in length of IVF stimulation or dose of stimulation medications. Patients in the MPA group saved an average of $491 ± $119 on medications, had an average of one less monitoring visit (4.4 ± 0.9 vs. 5.6 ± 1.1; P<.01), and 5.0 ± 1.2 less injections per cycle. When adjusting for age and ovarian reserve, protocol group (MPA vs. control) did not influence having an embryo available for transfer (76.6% vs. 73.4%; adjusted RR = 1.05; 95% CI, 0.94, 1.14). CONCLUSION For ovulatory suppression during IVF cycles, MPA was effective at preventing ovulation while demonstrating similar cycle and reproductive outcomes, with the additional benefits of patient cost savings, increased convenience with decreased number of visits, and fewer injections.

Abstract
Luteinizing hormone (LH) is present throughout the natural follicular phase. However, the debate is still not settled on whether LH is needed during ovarian stimulation in IVF. This commentary looks at the evolution of this debate, mentioning three elephants in the room that were ignored by the Pharma industry, professional organizations, and clinicians alike: 1. The different endocrinology between the long agonist and the antagonist protocols. 2. The fixed dose of the two most widely commercially available antagonist preparations, namely cetrorelix and ganirelix. 3. The fact that most research in this area uses population-based criteria, ignoring endocrine parameters. Individual genetics of the LH receptor gene may also serve to individualize LH needs during stimulation; however, the jury is still out regarding this approach. CONCLUSIONS: Individual endocrine and genetics parameters may shed meaningful light on the question of LH supplemental during ovarian stimulation.

Live birth rate of gonadotropin-releasing hormone antagonist versus luteal phase gonadotropin-releasing hormone agonist protocol in IVF/ICSI: a systematic review and meta-analysis.

Abstract
In vitro fertilization (IVF) and embryo transfer and intracytoplasmic sperm injection (ICSI) have allowed millions of infertile couples to achieve pregnancy. As an essential part of IVF/ICSI enabling the retrieval of a high number of oocytes in one cycle, controlled ovarian stimulation (COS) treatment mainly composes of the standard long gonadotrophin-releasing hormone agonist (GnRH-a) protocol and the gonadotrophin-releasing hormone antagonist (GnRH-ant) protocol. However, the effectiveness of GnRH-ant protocol is still debated because of inconsistent conclusions and insufficient subgroup analyses. This systematic review and meta-analysis included a total of 52 studies, encompassing 5193 participants in the GnRH-ant group and 4757 in the GnRH-a group. The findings of this study revealed that the GnRH-ant protocol is comparable with the long GnRH-a protocol when considering live birth as the primary outcome, and it is a favourable protocol with evidence reducing the incidence of ovarian hyperstimulation syndrome in women undergoing IVF/ICSI, especially in women with polycystic ovary syndrome. Further research is needed to compare the subsequent cumulative live birth rate between the two protocols among the general and poor ovarian response patients since those patients have a lower clinical pregnancy rate, fewer oocytes retrieved or fewer high-grade embryos in the GnRH-ant protocol.

A systematic review and network meta-analysis. Hum Reprod Update 2023; 29:307-326. [PMID: 36594696 PMCID: PMC10152179 DOI: 10.1093/humupd/dmac040] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 11/09/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Several GnRH antagonist protocols are currently used during COS in the context of ART treatments; however, questions remain regarding whether these protocols are comparable in terms of efficacy and safety. OBJECTIVE AND RATIONALE A systematic review followed by a pairwise and network meta-analyses were performed. The systematic review and pairwise meta-analysis of direct comparative data according to the PRISMA guidelines evaluated the effectiveness of different GnRH antagonist protocols (fixed Day 5/6 versus flexible, ganirelix versus cetrorelix, with or without hormonal pretreatment) on the probability of live birth and ongoing pregnancy after COS during ART treatment. A frequentist network meta-analysis combining direct and indirect comparisons (using the long GnRH agonist protocol as the comparator) was also performed to enhance the precision of the estimates. SEARCH METHODS The systematic literature search was performed using Embase (Ovid), MEDLINE (Ovid), Cochrane Central Register of Trials (CENTRAL), SCOPUS and Web of Science (WOS), from inception until 23 November 2021. The search terms comprised three different MeSH terms that should be present in the identified studies: GnRH antagonist; assisted reproduction treatment; randomized controlled trial (RCT). Only studies published in English were included. OUTCOMES The search strategy resulted in 6738 individual publications, of which 102 were included in the systematic review (corresponding to 75 unique studies) and 73 were included in the meta-analysis. Most studies were of low quality. One study compared a flexible protocol with a fixed Day 5 protocol and the remaining RCTs with a fixed Day 6 protocol. There was a lack of data regarding live birth when comparing the flexible and fixed GnRH antagonist protocols or cetrorelix and ganirelix. No significant difference in live birth rate was observed between the different pretreatment regimens versus no pretreatment or between the different pretreatment protocols. A flexible GnRH antagonist protocol resulted in a significantly lower OPR compared with a fixed Day 5/6 protocol (relative risk (RR) 0.76, 95% CI 0.62 to 0.94, I2 = 0%; 6 RCTs; n = 907 participants; low certainty evidence). There were insufficient data for a comparison of cetrorelix and ganirelix for OPR. OCP pretreatment was associated with a lower OPR compared with no pretreatment intervention (RR 0.79, 95% CI 0.69 to 0.92; I2 = 0%; 5 RCTs, n = 1318 participants; low certainty evidence). Furthermore, in the network meta-analysis, a fixed protocol with OCP resulted in a significantly lower OPR than a fixed protocol with no pretreatment (RR 0.84, 95% CI 0.71 to 0.99; moderate quality evidence). The surface under the cumulative ranking (SUCRA) scores suggested that the fixed protocol with no pretreatment is the antagonist protocol most likely (84%) to result in the highest OPR. There was insufficient evidence of a difference between fixed/flexible or OCP pretreatment/no pretreatment interventions regarding other outcomes, such as ovarian hyperstimulation syndrome and miscarriage rates. WIDER IMPLICATIONS Available evidence, mostly of low quality and certainty, suggests that different antagonist protocols should not be considered as equivalent for clinical decision-making. More trials are required to assess the comparative effectiveness of ganirelix versus cetrorelix, the effect of different pretreatment interventions (e.g. progestins or oestradiol) or the effect of different criteria for initiation of the antagonist in the flexible protocol. Furthermore, more studies are required examining the optimal GnRH antagonist protocol in women with high or low response to ovarian stimulation.

Ovarian Stimulation with FSH Alone versus FSH plus a GnRH Antagonist for Elective Freezing in an Oocyte Donor/Recipient Programme: A Protocol for a Pilot Multicenter Observational Study. J Clin Med 2023; 12:jcm12072743. [PMID: 37048828 PMCID: PMC10095010 DOI: 10.3390/jcm12072743] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 04/04/2023] [Accepted: 04/05/2023] [Indexed: 04/14/2023] Open
Abstract
Preliminary data have shown that it is possible to attempt in vitro fertilization (IVF) treatment in fresh cycles without the use of a gonadotropin-releasing hormone (GnRH) antagonist or any other medication to prevent the luteinizing hormone (LH) surge during ovarian stimulation. To date, there is no information on this topic in the context of a prospective controlled trial. However, as prevention of the LH surge is an established procedure in fresh cycles, the question is whether such a study can be performed in frozen cycles. We aim to perform a pilot study in order to compare the efficacy of a protocol using FSH alone with that of a protocol using follicle-stimulating hormone (FSH) plus a GnRH antagonist for controlled ovarian hyperstimulation (COH) in cycles of elective freezing in the context of a donor/recipient program. This is a seven-center, two-arm prospective pilot cohort study conducted at the respective Assisted Reproductive Units in Greece. The hypothesis to be tested is that an ovarian stimulation protocol that includes FSH alone without any LH surge prevention regimens is not inferior to a protocol including FSH plus a GnRH antagonist in terms of the clinical outcome in a donor/recipient model. The results of the present study are expected to show whether the addition of the GnRH antagonist is necessary in terms of the frequency of LH secretory peaks and progesterone elevations >1 ng/mL during the administration of the GnRH antagonist according to the adopted frequency of blood sampling in all Units.

Doroftei B, Ilie OD, Anton N, Marcu OA, Scripcariu IS, Ilea C. A Narrative Review Discussing the Efficiency of Personalized Dosing Algorithm of Follitropin Delta for Ovarian Stimulation and the Reproductive and Clinical Outcomes. Diagnostics (Basel) 2023; 13:177. [PMID: 36672987 PMCID: PMC9858569 DOI: 10.3390/diagnostics13020177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 12/24/2022] [Accepted: 12/30/2022] [Indexed: 01/06/2023] Open
Abstract
Background: Follitropin delta is the third recombinant human follicle-stimulating hormone (r-hFSH) expressed in a host cell line of human fetal retinal origin that currently emphasizes that the actual tendency of administration is a personalized dosing algorithm based on the anti-Müllerian hormone (AMH) and body mass index (BMI) for ovarian stimulation. Methods: In this context, we aimed, in the present manuscript, to gather all available data published between 2018-2022 regarding the co-administration and administration of follitropin delta and the clinical outcomes reported following an in vitro fertilization (IVF). Results: Follitropin delta is non-inferior in contrast to its previously launched agents for ovarian stimulation, enhancing a similar-to-superior response reflected by both the reproductive and pregnancy outcomes in parallel with a low risk of ovarian hyperstimulation syndrome (OHSS), being well tolerated. The body weight and AMH level are factors that may influence the outcome in a patient. Despite controversy and results that refute these arguments on several occasions, follitropin delta exceeds the benefits of conventional dosing with either follitropin alfa or follitropin beta. Thus, all post hoc, derived analyses and subsets of patients that participated in subsequent studies support this statement. Conclusions: Despite the relatively limited spectrum of data in the current literature, most authors brought potent proof, supporting the subsequent use of this drug depending on the patient's profile and overcoming ethnic-related limitations. Although others contradict these observations, this topic and drug possess substantial potential, which is why additional studies are mandatory to fill the existing gaps in our knowledge and expand these experiences at a larger scale supported by the obtained reproductive and clinical outcomes that clearly indicate an overcoming of all limitations.

Progestin-primed ovarian stimulation versus GnRH antagonist protocol in poor responders: Risk of premature LH surge and outcome of oocyte retrieval. J Formos Med Assoc 2023; 122:29-35. [PMID: 36123235 DOI: 10.1016/j.jfma.2022.08.023] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 08/28/2022] [Accepted: 08/31/2022] [Indexed: 01/10/2023] Open
Abstract
PURPOSE For poor ovarian responders (PORs), gonadotropin-releasing hormone (GnRH) antagonist was commonly used for prevention of premature LH surge during controlled ovarian stimulation (COS) over the past two decades. The application of progestin-primed ovarian stimulation (PPOS) recently increased, but the role of PPOS for PORs was uncertain. We aimed to analyze the incidence of premature luteinizing hormone (LH) surge and the outcome of oocyte retrieval among PPOS and GnRH antagonist protocol for PORs. METHODS This was a single-center retrospective study, which enrolled the PORs (defined by the Bologna criteria) undergoing COS with PPOS or flexible GnRH antagonist protocol during January 2018 to December 2021. We compared the incidence of premature LH surge (LH > 10 mIU/mL) and the outcome of oocyte retrieval between the PPOS group and the GnRH antagonist group. RESULTS A total of 314 women were recruited, with 54 in the PPOS group and 260 in the GnRH antagonist group. The PPOS group had lower incidence of premature LH surges compared with the GnRH antagonist protocol group (5.6% vs 16.9%, P value 0.035). There was no significant difference between the two groups regarding the number of oocytes retrieved (3.4 vs 3.8, P value 0.066) and oocyte retrieval rates (88.9% vs 88.0%, P value 0.711). CONCLUSION Compared with PPOS, GnRH antagonist protocol had higher risk of premature LH surges for PORs but may not affect pregnancy rates. PPOS is suitable for oocyte or embryo cryopreservation, but should not totally replace GnRH antagonist protocol for patients undergoing in vitro fertilization (IVF).

Abstract
Objective To examine the efficacy of gonadotropin releasing hormone (GnRH) antagonist (GnRH-ant) protocol and the long GnRH agonist (GnRH-a) protocol during in vitro fertilization (IVF) therapy in patients with severe male infertile factors. Methods A total of 983 women with severe male factor infertility undergoing IVF therapy from 2017 to 2020 at one center were retrospectively analyzed. Patients were divided into the GnRH-ant group (n=527) and the GnRH-a group (n=456) according to their ovarian stimulation protocols. Patient baseline characteristics, ovarian stimulation characteristics, and clinical pregnancy outcomes were compared between the groups. The live birth rate was considered the main pregnancy outcome. Results GnRH-a group had a higher live birth rate compared with the GnRH-ant group (41.0% versus 31.3%, p=0.002). Moreover, the implantation (32.8% vs. 28.1%, p=0.033), biochemical pregnancy (52.4% versus 44.8%, p=0.017), clinical pregnancy (49.3% versus 39.7%, p=0.002) and ongoing pregnancy rates (43.2% vs. 34.9%, p=0.008) were higher in GnRH-a group. For patients with one embryo transferred, the GnRH-a group demonstrated higher live birth (37.0% vs. 19.4%, p=0.010) and ongoing pregnancy rate (38.9% vs. 24.5%, p=0.046) than the GnRH-ant group. Among patients with two embryos transferred, the live birth rate was also higher in the GnRH-a group than in the GnRH-ant group, with no statistical difference. No significant differences were observed in the biochemical abortion rate, clinical miscarriage rate, early miscarriage rate, late miscarriage rate, heterotopic pregnancy rate, twin pregnancy rate, and birth sex ratio between the two groups. Conclusion For individuals with severe male infertility undergoing IVF, the GnRH-a protocol is considered a more efficient and feasible strategy with a higher live birth rate compared to the GnRH-ant protocol, especially in single embryo transfer.

Abstract
Background Timely and moderate luteinizing hormone (LH) supplementation plays positive roles in in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) cycles with long-acting gonadotropin-releasing hormone agonist (GnRHa) pituitary downregulation. However, the appropriate timing of LH supplementation remains unclear. Methods We carried out a retrospective cohort study of 2226 cycles at our reproductive medicine centre from 2018 to 2020. We mainly conducted smooth curve fitting to analyse the relationship between the dominant follicle diameter when recombinant LH (rLH) was added and the clinical pregnancy outcomes (clinical pregnancy rate or early miscarriage rate). In addition, total cycles were divided into groups according to different LH levels after GnRHa and dominant follicle diameters for further analysis. Results Smooth curve fitting showed that with the increase in the dominant follicle diameter when rLH was added, the clinical pregnancy rate gradually increased, and the early miscarriage rate gradually decreased. Conclusions In long-acting GnRHa downregulated IVF/ICSI-ET cycles, the appropriate timing of rLH supplementation has a beneficial impact on the clinical pregnancy outcome. Delaying rLH addition is conducive to the clinical pregnancy rate and reduces the risk of early miscarriage.

Abstract
Assisted reproduction technology has two significant problems: low success rates and multiple pregnancies. Because of these problems, the priority in IVF clinics is to develop a potential diagnostic test that can be used to select the embryos with the ultimate developmental competence. Aneuploidy screening as embryo selection criteria will ensure that the transferred embryos are euploid and high implantation rate. We hypothesize that aneuploidy in human preimplantation embryos could be discriminated by their amino acid metabolism profile in the spent culture media. Preimplantation genetic testing for aneuploidy results and spent embryo culture medium amino acid content were analyzed for 58 couples. The next-generation sequencing technique was used and coupled with TE biopsy. Forty euploid and 71 aneuploid blastocysts were evaluated. Embryos were cultured individually until day 5 or 6 of embryo development. Spent culture medium was collected after finishing the culture. There was no statistical difference between D3 and D5 embryo morphology between euploid and aneuploid embryos (p > .05). Eight amino acids, including SER, GLY, HIS, ARG, THR, ALA, PRO, and TYR, were detected in the culture medium from the blank control group, euploid group, and aneuploid group. Only TYR amino acid concentration was found significantly higher in the aneuploid group compared to the euploid group (p < .003). Tyrosine amino acid levels equal to and above 76.38 µmol/L could be considered aneuploid. Aneuploid embryos demonstrate altered amino acid turnover in vitro relative to euploid counterparts. A noninvasive method of amino acid profiling will be of value as a tool for routine preimplantation embryo selection among all patient groups.

Abstract
This study aimed to investigate the efficacy of Ganilever pre-filled syringe (PFS), a newly developed ganirelix acetate, for the inhibition of premature luteinising hormone (LH) surge in in vitro fertilisation (IVF). A prospective randomised controlled study was conducted (NCT03051087). A total of 236 women (Ganilever group: 114, Orgalutran group: 122) were finally analysed. The patients with LH of >10 mIU/mL on the day of human chorionic gonadotropin (hCG) injection were 0 (0.0%) and 3 (2.5%) in the Ganilever and Orgalutran groups, respectively (p= .25). The number of retrieved oocytes from two groups did not show any significant difference (12.0 ± 6.4 vs. 11.8 ± 6.3, p= .73). Furthermore, the two groups did not show significant differences in the number of good-quality oocytes and embryo, and the rate of fertilisation. Similar safety profiles were also observed. In conclusion, Ganilever PFS showed comparable IVF outcomes and safety profile in IVF, as compared to the Orgalutran. Impact StatementWhat is already known on this subject? Premature LH surge during controlled ovarian stimulation results in the induction of luteinisation of the immature follicles. Thus, gonadotrophin-releasing hormone (GnRH) antagonist protocol was suggested as an option for suppression of premature LH surge. Currently, one of GnRH antagonists being widely used is ganirelix acetate (Orgalutran®; Organon, Oss, The Netherlands). Ganilever pre-filled syringe (PFS) is a newly developed GnRH antagonist containing ganirelix acetate as an active ingredient.What do the results of this study add? Our study demonstrated that Ganilever PFS showed comparable IVF outcomes and patient safety profile in infertile women undergoing in IVF-ET, as compared to the Orgalutran.What are the implications of these findings for clinical practice and/or further research? The results of our study will provide another available GnRH antagonist to be used in patients with IVF.

Abstract
OBJECTIVE The aim of the present retrospective study was to investigate the effectiveness of single-dose gonadotropin releasing hormone (GnRH) antagonist administration, the day after human chorionic gonadotropin (hCG) triggering for final oocyte maturation, on the prevention of premature luteinization in patients with diminished ovarian reserve in in-vitro fertilization (IVF) cycles. The secondary objective of the study was to search the effect of this protocol on pregnancy outcomes. METHODS This is a retrospective study including 267 infertile patients who have single antral follicle seen with ultrasonography on the 2nd or 3rd day of the menstrual cycle before starting IVF treatment. We randomized patients into two groups. The case group comprised patients who had single-dose GnRH antagonist injection the day after hCG triggering formed, and the patients who had the standard treatment regime formed the control group. In both groups, the oocytes were collected 36 hours after hCG injection. RESULTS The premature ovulation rate was significantly low in the case group compared with the control group (6.86 versus 20.6% per scheduled cycle) (p = 0.022). Also, the oocyte retrieval rate (93.14 versus 67.87% per scheduled cycle) (p = 0.013), the oocyte maturity rate (79.42 versus 47.87%) (p = 0.041), the fertilization rate (65.68 versus 34.54%) (p = 0.018), and the embryo transfer rate per scheduled cycle (44.11 versus 18.78%) (p = 0.003) were higher in the GnRH antagonist group than in the control group. CONCLUSION The administration of GnRH antagonist the day after hCG trigger in IVF treatments of patients with diminished ovarian reserve enabled a significant decrease in the rate of premature ovulation but had no effect on live birth rate.

Abstract
Filariasis is a common parasitic infection in India. It is rare to find neglected cases of Filariasis nowadays. We reported the presence of microfilaria species in the follicular fluid of an egg donor undergoing an ovum pick up procedure. She was a 23-year-old egg donor who underwent stimulation using the GnRH antagonist protocol. Antagonist protocol is one of the standard protocols used for controlled ovarian hyperstimulation as a part of the IVF/ICSI(in-vitro fertilization / intracytoplasmic sperm injection) procedure where GnRH antagonist (cetrorelix) is used to suppress the endogenous LH surge. Her baseline investigations were normal, with no significant history suggestive of any worm infestations. During the ovum pickup procedure, follicular fluid revealed the presence of worm-like structures suggestive of larvae of some parasites. The follicular fluid was sent to the microbiology department along with the blood sample to confirm the parasite species. The parasite was found to be the larvae of W. Bancroft. The oocytes were of poor quality and were discarded. The patient was treated with Diethylcarbamazine citrate. There are so many reports about scrotal Filariasis, but rare literature quotes ovarian Filariasis.

FASEB J 2021; 35:e21696. [PMID: 34085322 DOI: 10.1096/fj.202100406r] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 04/29/2021] [Accepted: 05/11/2021] [Indexed: 12/25/2022]
Abstract
During the in vitro fertilization treatment, human chorionic gonadotrophin (hCG) is routinely used as a substitute for the natural endogenous LH surge during the final stage of oocyte maturation. However, it does not provide the FSH surge observed in the mid-cycle of the natural cycle. To date, whether the FSH surge can improve oocyte quality and pregnancy outcomes remains unknown. Randomized controlled trials comparing the following four trigger methods to conventional hCG were examined: GnRH agonist (GnRHa), kisspeptin, GnRHa plus hCG (dual trigger), and FSH plus hCG (FSH co-trigger). The results showed that the use of dual triggers was associated with a significantly higher number of retrieved cumulus-oocyte complexes (COCs) (weighted mean difference [WMD] 1.625, 95% CI 0.684-2.565), retrieved mature oocytes (WMD 0.986, 95% CI 0.426-1.545) and fertilized (2PN) oocytes (WMD 0.792, 95% CI 0.083-1.501), compared with the use of hCG. However, there was no significant difference between the two groups in terms of pregnancy rate. The FSH co-trigger resulted in significantly higher rates of 2PN oocytes retrieved than the hCG trigger (WMD 0.077, 95% CI 0.028-0.126). Notably, the risk of OHSS did not differ among the three treatment groups compared to that of the hCG group. This review protocol was registered with PROSPERO (CRD 42020194201).

Does time interval between GnRH antagonist and GnRH agonist trigger in GnRH antagonist cycles matter? Reprod Biomed Online 2021; 43:233-238. [PMID: 34215488 DOI: 10.1016/j.rbmo.2021.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 04/28/2021] [Accepted: 05/01/2021] [Indexed: 10/21/2022]
Abstract
RESEARCH QUESTION What is a suitable time interval between the last GnRH antagonist exposure and GnRH agonist (GnRHa) triggering for final follicular maturation? DESIGN A retrospective cohort study including 413 patients undergoing GnRH antagonist cycles in which GnRHa trigger was used, either solely or as a dual trigger. The primary outcome measure was the follicle/mature oocyte ratio. Cycles were analysed according to the time interval between the last GnRH antagonist exposure and the GnRHa triggering: Group 1 included patients with a 12-14 h interval; Group 2: 7-10 h interval; Group 3: 5-6 h interval and Group 4: 2-4 h interval. LH concentration was measured 11-13 h post-GnRHa injection. RESULTS Median LH value was 65 IU/l. There was a weak but significant correlation between basal LH and the LH surge (R2 = 0.137, P < 0.001). Although square root LH values differed significantly between study groups (P < 0.001; higher in Groups 2 and 3), the follicle/mature oocyte ratio was not different across the four antagonist-agonist interval groups and no correlation was detected between the post-trigger LH concentration and the follicle/oocyte ratio (R2 = 0.011). In a model integrating age, day 3 FSH concentration, maximal oestradiol and body mass index along with the study groups, none of these factors was significantly related to the follicle/mature oocyte outcome ratio. Insufficient surge (LH < 15 IU/l) occurred in 14 (3.4%) cases. Rates of insufficient LH surge did not differ significantly between the groups (2.4%, 3.2%, 3.4% and 7.1% in Groups 1 to 4, respectively; P = 0.5). CONCLUSIONS LH concentrations post-GnRHa trigger differ in regard to antagonist-agonist intervals, but the follicle/mature oocyte ratio achieved was not affected.

Abstract
In reproductive medicine, the needs and desires of infertility patients drive future research, with the most important outcome being live birth of a baby. Large, multicenter, randomized clinical trials are considered the best research tool to evaluate the effectiveness of medical interventions, but they can often take a long time to find definitive answers. Advances in individual participant data (IPD) and network meta-analysis have enabled research questions to be answered more quickly, but better planning could streamline this process further. To harmonize research findings that are taking place globally in this way, it is crucial that the same outcomes are collected in clinical trials conducted in reproductive medicine. Furthermore, the conduct of clinical trials often requires collaboration on an international scale; however, individual countries have their own processes for research prioritization and delivery. We describe the perspective of high- and low-resourced settings and industry as well as the mechanisms of prioritization and coordination that are in place in different settings. In addition, we discuss the importance of the patient perspective, which can help shape the research question, clinical trial design, and the logistical operations of trial delivery. The need for increased global collaboration and coalitions within and between stakeholders is evident for the research community to accelerate advances and maximize benefits in reproductive medicine.

Abstract
PURPOSE To evaluate the factors that affect the incidence of euploid balanced embryos and interchromosomal effect (ICE) in carriers of different structural rearrangements. METHODS This retrospective study includes 95 couples with reciprocal translocations (RecT) and 36 couples with Robertsonian translocations (RobT) undergoing Preimplantation Genetic Testing for Structural Rearrangements (PGT-SR) between March 2016 and July 2019. Next-generation sequencing (NGS) was the technique used coupled with trophectoderm (TE) biopsy. Only cases with females under 38 years were included. A total of 532 blastocysts were evaluated. RESULTS The euploidy rate was similar in RobT when compared with RecT carriers [57/156 (36.5%) vs. 112/376 (29.8%), p = 0.127]. The pure ICE rate was significantly higher in RobT carriers [48/156 (30.8%) vs. 53/376 (14.1%), p < 0.001] than it was in RecT carriers. Female age was the independent factor for the probability of obtaining a euploid embryo in RecT and RobT carriers, and increasing female age decreases the probability of obtaining a euploid embryo. In RecT carriers, no significant differences were observed in euploidy rates, pure ICE, or combined ICE according to the length of the translocated fragment and the chromosome group. However, total ICE was significantly lower when there was a breakpoint in the short chromosome arm together with a breakpoint in the long arm [(44/158 (27.8%) for pq or qp, 51/155 (32.9%) for pp and 30/63 (47.6%) for qq; p = 0.02]. CONCLUSION The incidence of euploid/balanced blastocysts was similar in both types of translocations. However, there was a significant increase in pure ICE in RobT compared to RecT carriers. In RecT carriers, the presence of the breakpoints in the long arm of the chromosomes involved in the rearrangement resulted in a higher total ICE.

Abstract
OBJECTIVE To compare the cumulative live birth rate (CLBR) of the progestin-primed ovarian stimulation (PPOS) protocol with that of the flexible GnRH antagonist protocol in patients with poor prognosis diagnosed per the POSEIDON criteria. METHODS This was a retrospective cohort study. Low-prognosis women who underwent IVF/ICSI at the Reproductive Center of Third Affiliated Hospital of Zhengzhou University between January 2016 and January 2019 were included according to the POSEIDON criteria. The CLBR was the primary outcome of interest. The secondary outcome measures were the numbers of oocytes retrieved, 2PN embryos, available embryos and time to live birth. RESULTS A total of 1329 women met the POSEIDON criteria for analysis. For POSEIDON group 1, the dosage of gonadotropin (Gn) was higher in the PPOS group than in the GnRH antagonist group (2757.3 ± 863.1 vs 2419.2 ± 853.1, P=0.01). The CLBR of the PPOS protocols was 54.4%, which was similar to the rate of 53.8% in the GnRH antagonist group. For POSEIDON group 2, the number of available embryos was higher in the PPOS group (2.0 ± 1.7 vs 1.6 ± 1.4, P=0.02) than in the GnRH antagonist group. However, the CLBRs of the two groups were similar (18.1% vs 24.3%, P=0.09). For POSEIDON groups 3 and 4, there were no statistically significant differences in the number of oocytes retrieved, 2PN, available embryos or CLBR between the two protocols. After adjustments for confounding factors, the CLBR remained consistent with the unadjusted rates. In the POSEIDON group 1 population, the GnRH antagonist protocols had a shorter time to live birth (P=0.04). CONCLUSION For low-prognosis patients diagnosed per the POSEIDON criteria, the CLBR of PPOS protocols is comparable to that of GnRH antagonist protocols. In the POSEIDON group 1 population, the GnRH antagonist protocols resulted in a shorter time to live birth.

Abstract
OBJECTIVE To compare the clinical outcomes of dydrogesterone (DYG) and medroxyprogesterone (MPA) in the progestin-primed ovarian stimulation (PPOS) protocol for patients with poor ovarian response (POR). PATIENTS AND METHODS This was a retrospective cohort study. Women with POR who underwent IVF/ICSI at the Reproductive Center of Third Affiliated Hospital of Zhengzhou University between January 2020 and January 2021 were included. The primary outcome measure of our study was the number of oocytes retrieved. The secondary outcome measures in the present study were the number of 2PN, number of available embryos, oocyte retrieval rate, fertilization rate, viable embryo rate per oocyte retrieved, cancellation rate and pregnancy outcomes of the first embryo transfer cycle, including the biochemical pregnancy, clinical pregnancy and miscarriage rates. RESULTS In total, 118 women underwent hMG +DYG protocols, and 692 women who underwent hMG +MPA met the Bologna criteria for POR. After baseline characteristics were balanced using the PSM model, 118 hMG +DYG protocols were matched to 118 hMG +MPA protocols, and the baseline characteristics were comparable between the two groups. The numbers of oocytes retrieved, 2PN, and available embryos and the oocyte retrieval rate, fertilization rate, viable embryo rate per oocyte retrieved and cancellation rate of the hMG+DYG and hMG+MPA protocols were comparable. Altogether, 66 women in the hMG+DYG group and 87 women in the hMG+MPA group underwent first embryo transfers. In the hMG+DYG group, 81.8% (54/66) of the patients underwent cleavage embryo transfers; similarly, 79.3% (69/87) of patients in the hMG+MPA group had cleavage embryo transfers (P=0.70).The biochemical pregnancy rate of the hMG+DYG group was 42.4%, and this was comparable to the rate in the hMG+DYG group, at 34.5% (P=0.32). The clinical pregnancy rates were similar between the two groups (36.4% vs. 31.0%, P=0.49), and there was no significant difference in the rate of miscarriage between the two groups (12.5% vs. 29.6%, P=0.14). CONCLUSION For women with POR, the clinical outcome of the hMG + DYG group was similar to that of the hMG + MPA group, indicating that both combinations can be useful options for PPOS protocols.

Abstract
Context/Background: A premature luteinizing hormone (LH) surge, in in vitro fertilization (IVF) cycles with gonadotropin-releasing hormone (GnRH)-antagonist downregulation, leads to cycle cancellation. Currently, risk factors for the development of premature LH surge remain unknown. Objective: The aim of the study was to determine the incidence and identify the contributing factors for premature LH surge in IVF cycles with GnRH antagonist suppression. Design: This was a retrospective cohort study. Setting: IVF-embryo transfer program at a fertility and research center. Materials and Methods: The study included all patients undergoing IVF from December 1, 2014, to November 30, 2018, in whom GnRH-antagonist (cetrorelix 0.25 mg/d) flexible protocol was used. The primary outcome measure was the identification of premature LH surges (documented by a 2.5-fold increase in LH from the baseline above a threshold of 17 mIU/mL) with or without a decrease in E2 and appearance of free fluid on ultrasound. Results: Premature LH surges occurred in 15 (2.16%) of 692 patients undergoing IVF with GnRH-antagonist suppression. Patients with premature surges had significantly lower ovarian reserve as compared to the controls (as seen from their higher age group, higher day 2 follicle-stimulating hormone (FSH), lower antral follicle counts, and lower anti-Müllerian hormone). Conclusions: Premature LH surge in a GnRH-antagonist cycle can lead to cycle cancellation and disappointment. Although this is a rare event, the incidence is higher in patients with diminished ovarian reserve. Further studies are needed to determine if giving the human chorionic gonadotropin trigger a day earlier or giving higher doses of GnRH-antagonist can benefit such cases.

Abstract
OBJECTIVE To investigate a possible correlation between chromosomal aberrations and paternal age, analyzing embryos derived from young oocyte donors, with available preimplantation genetic testing for aneuploidy results from day 5/6 trophectoderm biopsy obtained by next-generation sequencing for all 24 chromosomes. DESIGN Retrospective cohort study. SETTING Canadian fertility centre. PATIENT(S) A total of 3,118 embryos from 407 male patients, allocated into three paternal age groups: group A, ≤39 years (n = 203); group B, 40-49 years (n = 161); group C, ≥50 years (n = 43). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The primary outcomes were aneuploidy, euploidy, mosaicism, and blastocyst formation rates. Secondary endpoints were comparison of specific chromosome aneuploidy, segmental and complex (involving two chromosomes + mosaicism >50%) aneuploidy, and analysis of overall percentage of chromosomal gains and losses within each group. RESULT(S) The study included 437 in vitro fertilization (IVF) antagonist cycles using 302 oocyte donors in which preimplantation genetic testing for aneuploidy was performed. Overall, 70.04% of embryos were euploid, 13.9% were aneuploid, and 16.06% were mosaic. No significant differences among paternal age groups A, B, and C were found in euploidy rates (69.2%, 70.6%, 71.4%, respectively), aneuploidy rates (14.7%, 12.8%, 13.9%, respectively) or mosaicism rates (16.1%, 16.6%, 13.6%; respectively). The fertilization rate was lower in group C compared with group B (76.35% vs. 80.09%). No difference was found in blastocyst formation rate between the study groups (median 52% [interquartile range, 41%, 67%] vs. 53% [42%, 65%] vs. 52% [42%, 64%], respectively). A generalized linear mixed model regression analysis for embryo ploidy rates found older oocyte donor age to be independently associated with embryo aneuploidy (odds ratio = 1.041; 95% CI, 1.009-1.074). The rate of segmental aneuploidies was significantly higher in the older versus younger paternal age group (36.6% vs. 19.4%). CONCLUSION(S) No association was found between paternal age and aneuploidy rates in embryos derived from IVF cycles using young oocyte donors, after adjusting for donor, sperm, and IVF cycle characteristics. Advanced paternal age ≥ 50, compared with younger paternal ages, was associated with a lower fertilization rate and increased rate of segmental aberrations.

Abstract
Background To assess the predictive value of patient characteristics, controlled ovarian stimulation and embryological parameters on the live birth outcome of single euploid frozen-warmed blastocyst transfer (FBT). Methods This was a retrospective cohort study including 707 single FBTs after preimplantation genetic testing for aneuploidy (PGT-A) that were performed from October 1, 2015, to January 1, 2018. The effects of patient-, cycle- and embryology-related parameters on the live birth outcome after FBT were assessed. Results In the subgroup analysis based on live birth, patients who achieved a live birth had a significantly lower body mass index (BMI) than patients who did not achieve a live birth (22.7 (21.5–24.6) kg/m2 vs 27 (24–29.2) kg/m2, p<0.001). The percentage of blastocysts with inner cell mass (ICM) A or B was significantly higher among patients achieving a live birth, at 91.6% vs. 82.6% (p<0.001). Day-5 biopsies were also more prevalent among patients achieving a live birth, at 82.9% vs 68.1% (p<0.001). On the other hand, the mitochondrial DNA (mtDNA) levels were significantly lower among cases with a successful live birth, at 18.7 (15.45–23.68) vs 20.55 (16.43–25.22) (p = 0.001). The logistic regression analysis showed that BMI (p<0.001, OR: 0.789, 95% CI [0.734–0.848]), day of trophectoderm (TE) biopsy (p<0.001, OR: 0.336, 95% CI [0.189–0.598]) and number of previous miscarriages (p = 0.004, OR: 0.733, 95% CI [0.594–0.906]) were significantly correlated with live birth. Patients with elevated BMIs, cycles in which embryos were biopsied on day-6 and a higher number of miscarriages were at increased risks of reduced live birth rates. Conclusion A high BMI, an embryo biopsy on day-6 and a high number of miscarriages negatively affect the live birth rate after single euploid FBT.

Progestin vs. Gonadotropin-Releasing Hormone Antagonist for the Prevention of Premature Luteinizing Hormone Surges in Poor Responders Undergoing in vitro Fertilization Treatment: A Randomized Controlled Trial. Front Endocrinol (Lausanne) 2019; 10:796.

Abstract
Objective: Progestin was recently used as an alternative of gonadotropin-releasing hormone (GnRH) analog for preventing premature luteinizing hormone (LH) surge with the aid of vitrification techniques, however, limited data were available about the potential of progestin in poor responders undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment. We performed a randomized parallel controlled trial to investigate the difference of progestin and GnRH antagonist in poor responders. Methods: A total of 340 poor responders who met with Bologna criteria were randomly allocated into the progestin-primed ovarian stimulation (PPOS) group and GnRH antagonist group. Fresh embryo transfer was preferred in the GnRH antagonist group and freeze-all was performed in the PPOS group. The primary outcome was the incidence of premature LH surge, secondary outcomes were the number of retrieved oocytes, the number of viable embryos and the pregnancy outcomes. Results: The results showed that the incidence of premature LH surge in PPOS group was lower than that in antagonist group (0 vs. 5.88%, P < 0.05). In PPOS group, the average numbers of oocytes and viable embryos were comparable to those in GnRH antagonist group (3.7 ± 2.6 vs. 3.4 ± 2.4; 1.6 ± 1.7 vs. 1.4 ± 1.3, P > 0.05), the live birth rate was similar between the two groups (21.8 vs. 18.2%, RR 1.25 (95% confidence interval 0.73, 2.13), P > 0.05). Conclusions: The study demonstrated that PPOS had a more robust control for preventing premature LH rise than GnRH antagonist in poor responders, but PPOS in combination with freeze-all did not significantly increase the probability of pregnancy than GnRH antagonist protocol for poor responders.

Abstract
OBJECTIVE This study aimed to evaluate the effect of three days of GnRH antagonist pretreatment on the pregnancy outcomes of women with polycystic ovarian syndrome (PCOS) on GnRH antagonist protocols for IVF/ICSI. METHODS Fifty women with PCOS in the control group received conventional antagonist protocols, starting on day 2 of the cycle. In the pretreatment group (n=38), a GnRH antagonist was administered from day 2 of the menstrual cycle for three days. RESULTS Controlled ovarian stimulation (COS) duration and gonadotropin dosages were similar in both groups. The number of metaphase II (MII) oocytes, 2PN oocytes, embryos, along with implantation and clinical pregnancy rates, were higher in the pretreatment group when compared with controls, although the increment was not significant (P value ≥0.05). The chemical pregnancy rate was significantly higher in the pretreatment group. The rate of OHSS was significantly lower in the pretreatment than in the control group. CONCLUSION Women with PCOS offered early follicular phase GnRH antagonist pretreatment for three consecutive days had significantly fewer cases of OHSS and higher chemical pregnancy rates. There were trends toward greater numbers of MII oocytes, 2PN oocytes, and embryos, and higher clinical pregnancy rates in the pretreatment group.

Abstract
OBJECTIVE To look into current evidence exploring the added value of rLH supplementation to rFSH in GnRH analogues cycles, to identify groups of women that still have no evidence for adjuvant rLH therapy and to discuss ways that may advance research on this topic. METHODS Eight systematic reviews and meta-analyses exploring the benefit for pregnancy achievement of rLH supplementation, excluding other LH activity preparations, to GnRH analogues cycles in the ART setting were thoroughly evaluated. RESULTS Evidence exists to show that rLH supplementation seems to have added value for pregnancy achievement in women with poor ovarian response and in women ≥35 years of age employing the GnRH agonist protocol, while the evidence is still debatable when the GnRH antagonist is administered. In the general infertile population, rLH supplementation does not have added value in the GnRH-antagonist cycles while the evidence is still controversial when the GnRH agonist is employed. Whether rLH supplementation may have a benefit in some young, normo-gonadotropic women, who may develop LH deficiency following GnRH analogues, is still to be shown. The main task remains how to identify subgroups of women that may benefit from rLH supplementation. CONCLUSION An accurate definition of the LH threshold in GnRH analogue treated cycles may contribute to the discussion of which subgroups of women may benefit from adjuvant rLH therapy.

Abstract
The use of GnRH antagonists (GnRHant) is increasing in the ovarian stimulation protocol. Among several other benefits, GnRHant should prevent a premature luteinization and premature ovulation, the first described either as a 'reassuringly rare event' or 'frequent event', while the second as occurring more frequently in women with decreased ovarian reserve, advanced age and poor ovarian response. Two cases of associated premature luteinization and premature ovulation, during treatment with gonadotropins and GnRHant in IVF cycles, are here reported. In both cases, premature luteinization occurred and ovulation took place during ovarian stimulation protocols with exogenous gonadotropins and GnRHant, before reaching the criteria of hCG administration, regardless of the age of the patients and their ovarian reserve. Ovulation was documented by the disappearance of most of the developing follicles, by the transformation of endometrium from a triple line picture into a uniform hyper-echogenic image, by the presence of fluid in the pouch of Douglas, by the increase of progesterone plasma levels and the simultaneous reduction of estradiol plasma levels. This evidence can be important for a correct counseling with infertile patients in preparation for an IVF cycle.

Abstract
Sperm DNA fragmentation is a known etiology for male infertility. We evaluated the impact of sperm DNA fragmentation index (DFI) on blastocyst euploidy in IVF cycles with egg donors. This observational retrospective study, which was conducted in a university affiliated fertility clinic, included IVF-ICSI-pre-implantation Genetic Screening (PGS) egg donor cycles in which DFI was tested prior to IVF, between January 1st, 2014 and July 31st, 2016. Twenty-seven cycles with DFI > 15% were included in the study group and compared with 18 cycles of DFI < 15% within control group. Research group participants had significantly lower sperm count and motility (55.4*106/ml and 37.4%, respectively) compared with controls (92.5*106/ml and 55.7%, respectively, p < .05). The groups were similar in terms of donors' demography (age, BMI), ovarian reserve (AMH, AFC) and response to hormonal stimulation (E2 level on triggering day and number of retrieved eggs). Embryo development (from 2PN through day 3 embryos to blastocysts) was similar as well. The number of biopsied blastocysts from study and control groups was 171 and 87, respectively. PGS with array comprehensive genomic hybridization revealed comparable euploidy rates of 69.3% and 67.3%, respectively (p > .05). DFI did not have an impact on the blastocyst euploidy rate in IVF cycles with egg donors.

GnRH antagonist versus long agonist protocols in IVF: a systematic review and meta-analysis accounting for patient type. Hum Reprod Update 2018; 23:560-579.

Abstract
BACKGROUND Most reviews of IVF ovarian stimulation protocols have insufficiently accounted for various patient populations, such as ovulatory women, women with polycystic ovary syndrome (PCOS) or women with poor ovarian response, and have included studies in which the agonist or antagonist was not the only variable between the compared study arms. OBJECTIVE AND RATIONALE The aim of the current study was to compare GnRH antagonist protocols versus standard long agonist protocols in couples undergoing IVF or ICSI, while accounting for various patient populations and treatment schedules. SEARCH METHODS The Cochrane Menstrual Disorders and Subfertility Review Group specialized register of controlled trials and Pubmed and Embase databases were searched from inception until June 2016. Eligible trials were those that compared GnRH antagonist protocols and standard long GnRH agonist protocols in couples undergoing IVF or ICSI. The primary outcome was ongoing pregnancy rate. Secondary outcomes were: live birth rate, clinical pregnancy rate, number of oocytes retrieved and safety with regard to ovarian hyperstimulation syndrome (OHSS). Separate comparisons were performed for the general IVF population, women with PCOS and women with poor ovarian response. Pre-planned subgroup analyses were performed for various antagonist treatment schedules. OUTCOMES We included 50 studies. Of these, 34 studies reported on general IVF patients, 10 studies reported on PCOS patients and 6 studies reported on poor responders. In general IVF patients, ongoing pregnancy rate was significantly lower in the antagonist group compared with the agonist group (RR 0.89, 95% CI 0.82-0.96). In women with PCOS and in women with poor ovarian response, there was no evidence of a difference in ongoing pregnancy between the antagonist and agonist groups (RR 0.97, 95% CI 0.84-1.11 and RR 0.87, 95% CI 0.65-1.17, respectively). Subgroup analyses for various antagonist treatment schedules compared to the long protocol GnRH agonist showed a significantly lower ongoing pregnancy rate when the oral hormonal programming pill (OHP) pretreatment was combined with a flexible protocol (RR 0.74, 95% CI 0.59-0.91) while without OHP, the RR was 0.84, 95% CI 0.71-1.0. Subgroup analysis for the fixed antagonist schedule demonstrated no evidence of a significant difference with or without OHP (RR 0.94, 95% CI 0.79-1.12 and RR 0.94, 95% CI 0.83-1.05, respectively). Antagonists resulted in significantly lower OHSS rates both in the general IVF patients and in women with PCOS (RR 0.63, 95% CI 0.50-0.81 and RR 0.53, 95% CI 0.30-0.95, respectively). No data on OHSS was available from trials in poor responders. WIDER IMPLICATIONS In a general IVF population, GnRH antagonists are associated with lower ongoing pregnancy rates when compared to long protocol agonists, but also with lower OHSS rates. Within this population, antagonist treatment prevents one case of OHSS in 40 patients but results in one less ongoing pregnancy out of every 28 women treated. Thus standard use of the long GnRH agonist treatment is perhaps still the approach of choice for prevention of premature luteinization. In couples with PCOS and poor responders, GnRH antagonists do not seem to compromise ongoing pregnancy rates and are associated with less OHSS and therefore could be considered as standard treatment.

Abstract
The aim of this study was to evaluate the influence of body mass index (BMI) and ultrasound-estimated visceral adipose tissue deposits on oocyte quality and pregnancy rate in women undergoing Assisted Reproductive Technology (ART) procedures. The study included 58 women who underwent ART procedures. According to their BMI, the women were divided into normal weight and overweight/obese; an ultrasound evaluation of preperitoneal fat thickness (PFT) was also performed for each patient. The oocyte quality was then assessed, and samples of follicular fluid were collected from each woman, in order to evaluate the intrafollicular concentration of reactive oxygen species (ROS) as markers of oxidative stress and pro-inflammatory cytokines (IL-1β and IL-6) as markers of chronic inflammation. A negative correlation was found between BMI (as well as PFT) and the number of retrieved oocytes (r = -0.3; p <0.05 and r = -0.5; p < 0.001, respectively), good quality oocytes (r = -0.4; p = <0.05) and obtained embryos (r = -0.3; p < 0.05). In women undergoing ART procedures, BMI and PFT negatively influence the number of oocytes retrieved and their quality. However, on multivariable analysis, only age, PFT and number of retrieved oocytes affect the success rate of ART procedures.

Abstract
OBJECTIVE To compare self-reported quality of life, psychosocial well-being, and physical well-being during assisted reproductive technology (ART) treatment in 1,023 women allocated to either a short GnRH antagonist or long GnRH agonist protocol. DESIGN Secondary outcome of a prospective phase 4, open-label, randomized controlled trial. Four times during treatment a questionnaire on self-reported physical well-being was completed. Further, a questionnaire on self-reported quality of life and psychosocial well-being was completed at the day of hCG testing. SETTING Fertility clinics at university hospitals. PATIENT(S) Women referred for their first ART treatment were randomized in a 1:1 ratio and started standardized ART protocols. INTERVENTION(S) Gonadotropin-releasing hormone analogue; 528 women allocated to a short GnRH antagonist protocol and 495 women allocated to a long GnRH agonist protocol. MAIN OUTCOME MEASURE(S) Self-reported quality of life, psychosocial well-being, and physical well-being based on questionnaires developed for women receiving ART treatment. RESULT(S) Baseline characteristics were similar, and response rates were 79.4% and 74.3% in the GnRH antagonist and GnRH agonist groups, respectively. Self-reported quality of life during ART treatment was rated similar and slightly below normal in both groups. However, women in the GnRH antagonist group felt less emotional (adjusted odds ratio [AOR] 0.69), less limited in their everyday life (AOR 0.74), experienced less unexpected crying (AOR 0.71), and rated quality of sleep better (AOR 1.55). Further, women receiving GnRH agonist treatment felt worse physically. CONCLUSION(S) Women in a short GnRH antagonist protocol rated psychosocial and physical well-being during first ART treatment better than did women in a long GnRH agonist protocol. However, the one item on self-reported general quality of life was rated similarly. CLINICAL TRIAL REGISTRATION NUMBER NCT00756028.

Abstract
Increasing age is a risk factor for many diseases; therefore developing pharmacological interventions that slow down ageing and consequently postpone the onset of many age-related diseases is highly desirable. In this work we analyse data from the DrugAge database, which contains chemical compounds and their effect on the lifespan of model organisms. Predictive models were built using the machine learning method random forests to predict whether or not a chemical compound will increase Caenorhabditis elegans' lifespan, using as features Gene Ontology (GO) terms annotated for proteins targeted by the compounds and chemical descriptors calculated from each compound's chemical structure. The model with the best predictive accuracy used both biological and chemical features, achieving a prediction accuracy of 80%. The top 20 most important GO terms include those related to mitochondrial processes, to enzymatic and immunological processes, and terms related to metabolic and transport processes. We applied our best model to predict compounds which are more likely to increase C. elegans' lifespan in the DGIdb database, where the effect of the compounds on an organism's lifespan is unknown. The top hit compounds can be broadly divided into four groups: compounds affecting mitochondria, compounds for cancer treatment, anti-inflammatories, and compounds for gonadotropin-releasing hormone therapies.

Abstract
OBJECTIVE To evaluate the effectiveness and safety of gonadotropin-releasing hormone antagonist (GnRH-ant) protocol and gonadotropin-releasing hormone agonist (GnRH-a) long protocol in patients with normal ovarian reserve. METHODS We searched the PubMed (1992-2016), Cochrane Library (1999-2016), Web of Science (1950-2016), Chinese Biomedical Database (CBM, 1979-2016), and China National Knowledge Infrastructure (CNKI, 1994-2016). Any randomized controlled trials (RCTs) that compared GnRH-ant protocol and GnRH-a long protocol in patients with normal ovarian reserve were included, and data were extracted independently by two reviewers. The meta-analysis was performed by Revman 5.3 software. RESULTS Twenty-nine RCTs (6399 patients) were included in this meta-analysis. Stimulation days (mean difference (MD) [95% confidence interval (CI)] = -0.8 [-1.36, -0.23], P = 0.006), gonadotrophin (Gn) dosage (MD [95% CI] = -3.52 [-5.56, -1.48], P = 0.0007), estradiol (E2) level on the day of human chorionic gonadotrophin (HCG) administration (MD [95% CI] = -365.49 [-532.93, -198.05], P<0.0001), the number of oocytes retrieved (MD [95% CI] = -1.41 [-1.84, -0.99], P<0.00001), the embryos obtained (MD [95% CI] = -0.99 [-1.38, -0.59], P<0.00001), incidence of ovarian hyperstimulation syndrome (OHSS) (OR [95% CI] = 0.69 [0.57, 0.83], P<0.0001) were statistically significantly lower in GnRH-ant protocol than GnRH-a long protocol. However, the clinical pregnancy rate (OR [95% CI] = 0.90 [0.80, 1.01], P = 0.08), ongoing pregnancy rate (OR [95% CI] = 0.88 [0.77, 1.00], P = 0.05), live birth rate (OR [95% CI] = 0.95 [0.74, 1.09], P = 0.27), miscarriage rate (OR [95% CI] = 0.98 [0.69, 1.40], P = 0.93), and cycle cancellation rate (OR [95% CI] = 0.86 [0.52, 1.44], P = 0.57) showed no significant differences between the two groups. CONCLUSION GnRH-ant protocol substantially decreased the incidence of OHSS without influencing the pregnancy rate and live birth rate compared to GnRH-a long protocol among patients with normal ovarian reserve.

Abstract
Ovulatory dysfunction, which is common among women of reproductive age, often results in infertility. Over the last three decades, follicle-stimulating hormone (FSH), in the form of either urinary human menopausal gonadotropin or highly purified urinary FSH (uFSH), has been the mainstay in the treatment of women with ovulatory dysfunction. However, these preparations have several disadvantages, including variable composition, contamination with urinary proteins, and the limited availability of human menopausal urine from which uFSH is extracted. Recombinant human FSH (rhFSH) demonstrates higher purity and specific activity, and is suitable for subcutaneous administration. Additionally, rhFSH has facilitated the development of additional FSH products such as FSH-carboxy terminal peptide that possess different pharmacokinetic and pharmacodynamic properties and may provide more options in the treatment of ovulatory dysfunction and infertility. This article reviews the mechanism of action of FSH in folliculogenesis and ovulation, the current use of FSH in women for the medical management of infertility, and the published clinical experience to date with different rhFSH preparations.

Abstract
PURPOSE A recent dose-finding study showed no significant differences in number of mature oocytes, embryos and top-quality embryos when triptorelin doses of 0.2, 0.3 or 0.4 mg were used to trigger final oocyte maturation in oocyte donors co-treated with a gonadotropin-releasing hormone (GnRH) antagonist. This analysis investigated whether triptorelin dosing for triggering final oocyte maturation in oocyte donors induced differences in follicular fluid (FF) hormone levels and granulosa cell gene expression. METHODS This single-centre, randomised, parallel, investigator-blinded trial was conducted in oocyte donors undergoing a single stimulation cycle at IVFMD, My Duc Hospital, Ho Chi Minh City, Vietnam, from August 2014 to March 2015. A total of 165 women aged 18-35 years with body mass index <28 kg/m2, anti-Müllerian hormone >1.25 ng/mL, and antral follicle count ≥6 were randomised to three different triptorelin doses for trigger. The main outcome was concentration of steroid hormones in FF collected from the first punctured follicle on each side. Moreover, luteinising hormone receptor (LHR), 3β-hydroxy-steroid-dehydrogenase (3ßHSD) and inhibin-Ba (INHB-A) gene expression in cumulus and mural granulosa cells were investigated in a subset of women from each group. RESULTS Progesterone and oestradiol levels in FF did not differ significantly by trigger doses; findings were similar for 3βHSD, LHR and INHB-A gene expression in both cumulus and mural granulosa cells. CONCLUSIONS In women co-treated with a GnRH antagonist, no significant differences in FF steroid levels and granulosa cell gene expression were seen when different triptorelin doses were used to trigger final oocyte maturation.

Abstract
Equine pituitary gonadotropins (eLH, eFSH, eCG) are heterodimeric glycoprotein hormones with alpha (α) and beta (β) subunits. It is responsible for maintenance of pregnancy in mares during early gestation and fairly valuable for inducing superovulation in animals other than equines. The alpha subunit is common, while beta subunit is species-specific in all glycoprotein hormones. In the present investigation, molecular cloning and in silico characterization including homology modeling and molecular docking analysis of the equine chorionic gonadotropin (eCG) alpha subunit was carried out for gaining structural and functional insights into the eCG alpha subunit and its possible interaction with ganirelix, a gonadotropin-releasing hormone (GnRH) antagonist. The equine chorionic gonadotropin (eCG) alpha subunit expressed in pituitary gland was selected, amplified from total RNA, cloned and sequenced. The in silico analyses were made for homology modelling, structural details, epitope identification and chromosomal localization. Molecular docking studies of eCG alpha were undertaken with a drug ganirelix which is used to control ovulation and has antagonistic activity against GnRH. The protein sequence corresponding to selected open reading frame (ORF) was 99-100% similar with domesticated horse, Przewalski's horse, and 92-93% with Burchell's zebra and donkey. Molecular docking studies revealed the possible interaction of eCG alpha with ganirelix. The possible drug-macromolecule interactions were visualized between eCG alpha and ganirelix. The study will provide structural insight into unique sites and an alternate route of gonadotropin suppression applicable to assisted reproductive technologies.

Abstract
The recent development of vitrification technologies and the good outcomes obtained in assisted reproduction technologies have supported new indications for freezing and segmentation of treatment. Beyond OHSS prevention and avoidance of embryo transfers in the setting of an adverse endocrinological profile or endometrial cavity, we have witnessed a trend to shift fresh embryo transfers to frozen embryo transfers in many programs. We critically review the available evidence and suggest that freeze-all is not "for all," but should be individualized.

Abstract
OBJECTIVE We have previously reported a new luteal-phase ovarian stimulation (LPS) strategy for infertility treatment. The purpose of this study was to systematically assess the efficiency and safety of this strategy by comparing it with conventional ovarian stimulation protocols. DESIGN Retrospective cohort study. SUBJECTS Patients with normal ovarian reserve undergoing ovum pick-up (OPU) cycles between April 2012 and September 2013 were enrolled: 708 patients underwent the LPS protocol compared with 745 patients who underwent the mild treatment protocol and 1287 patients who underwent the short-term protocol. MEASUREMENTS Number of mature oocytes retrieved and top-quality embryos obtained, implantation rate, pregnancy rate, live birth and ongoing pregnancy rate and neonatal outcomes. RESULTS The numbers of mature oocytes retrieved and top-quality embryos obtained per OPU cycle were significantly increased in the LPS group (10·9 ± 7·6 and 4·6 ± 4·3, respectively) compared with the mild treatment group (3·7 ± 3·0 and 1·8 ± 1·8, respectively, both P < 0·001) or the short-term group (9·1 ± 5·5 and 3·7 ± 3·1, respectively, both P < 0·001). Moreover, the total gonadotrophin used was also the highest in the LPS group. No significant differences were identified in the implantation rate (35·5% vs 34·8%, P > 0·05), pregnancy rate (46·2% vs 43·7%, P > 0·05) or live birth and ongoing pregnancy rate (44·4% vs 41·7%, P > 0·05) per frozen-thawed embryo transfer (FET) cycle in the LPS and mild treatment groups, respectively. However, the LPS protocol achieved a higher implantation rate (35·5% vs 31·8%, P = 0·012), pregnancy rate (46·2% vs 41·9%, P = 0·041), and live birth and ongoing pregnancy rate (44·4% vs 39·2%, P = 0·012) compared with the short-term protocol. Neonatal outcomes in the LPS group were similar to the other two groups. CONCLUSIONS The available data suggest that LPS is a feasible strategy for infertility treatment and complements the available follicular-phase ovarian stimulation strategies.

Abstract
The aim of this study was to investigate 2 quantification criteria to evaluate the developmental condition of follicles cohort and clarify their impacts upon the determining of human chorionic gonadotropin trigger timing and the reproductive outcome: the proportion of mature follicles in growing follicles cohort on the day of human chorionic gonadotropin trigger and the peak estradiol level per oocyte on the day of human chorionic gonadotropin administration.Of the patients who underwent in vitro fertilization/ intracytoplasmic sperm injection-embryo transfer from 2011 to 2013, 492 controlled ovarian hyperstimulation cycles using gonadotropin-releasing hormone antagonists reaching the ovum pick-up and fresh embryo-transfer stage were included. Patients were divided into 3 groups according to their ≥17 mm/≥10 mm follicles ratio on the day of human chorionic gonadotropin administration (Low proportion: ≤30%, Middle proportion: 30%-60%, High proportion: ≥60%). Patients were divided into 5 groups according to their peak estradiol level/oocyte (Group A: <100 pg/mL per oocyte, Group B: 100-199 pg/mL per oocyte, Group C: 200-299 pg/mL per oocyte, Group D: 300-399 pg/mL per oocyte, Group E ≥400 pg/mL per oocyte) as well. Comparison among groups was made regarding ovarian stimulation characteristics, fertilization rate, good quality embryo rate, implantation, pregnancy, and live birth rates.On the basis of ≥17 mm/≥10 mm follicles ratio, the number of oocyte retrieved in low proportion group is more than other 2 groups. Implantation rate, clinical pregnancy, and live birth rate in high proportion group were 25.8%, 42.7%, and 31.1%, respectively, which is highest in 3 groups, and statistical significance existed between high and middle proportion groups. When the division is based on peak estradiol level/oocyte, the number of oocyte retrieved of ≥400 pg/mL per oocyte Group was significantly lowest compared with the other 4 groups. Matured ovum rate, fertilization rate, and good quality embryos rate exhibited an increasing trend as the peak estradiol level/oocyte increased. While pregnancy rate, implantation rate, and live birth rate were found to be lower whenever estradiol/oocyte ratio exceeded 400 pg/mL per oocyte or less than 100 pg/mL per oocyte, and there is statistical difference.Patients with the proportion of mature follicle reaching 60% on the day of human chorionic gonadotropin trigger and peak estradiol/oocyte level within 100∼399 pg/mL range can get a better pregnancy and implantation rate.

Abstract
The release of corifollitropin alfa simplifies daily injections of short-acting recombinant follicular stimulating hormone (rFSH), and its widely-used protocol involves short-acting gonadotropins supplements and a fixed GnRH antagonist regimen, largely based on follicle size. In this study, the feasibility of corifollitropin alfa without routine pituitary suppression was evaluated. A total of 288 patients were stimulated by corifollitropin alfa on cycle day 3 following with routine serum hormone monitoring and follicle scanning every other day after 5 days of initial stimulation, and a GnRH antagonist (0.25 mg) was only used prophylactically when the luteinizing hormone (LH) was ≧ 6 IU/L (over half of the definitive LH surge). The incidence of premature LH surge (≧ 10 IU/L) was 2.4% (7/288) before the timely injection of a single GnRH antagonist, and the elevated LH level was dropped down from 11.9 IU/L to 2.2 IU/L after the suppression. Two hundred fifty-one patients did not need any antagonist (87.2% [251/288]) throughout the whole stimulation. No adverse effects were observed regarding oocyte competency (fertilization rate: 78%; blastocyst formation rate: 64%). The live birth rate per OPU cycle after the first cryotransfer was 56.3% (161/286), and the cumulative live birth rate per OPU cycle after cyrotransfers was 69.6% (199/286). Of patients who did and did not receive GnRH antagonist during stimulation, no significant difference existed in the cumulative live birth rates (78.4% vs. 68.3%, p = 0.25). The results demonstrated that the routine GnRH antagonist administration is not required in the corifollitropin-alfa cycles using a flexible and hormone-depended antagonist regimen, while the clinical outcome is not compromised. This finding reveals that the use of a GnRH antagonist only occasionally may be needed.

Abstract
STUDY QUESTION Is the risk of severe ovarian hyperstimulation syndrome (OHSS) similar in a short GnRH antagonist and long GnRH agonist protocol in first cycle IVF/ICSI patients less than 40 years of age?. SUMMARY ANSWER There is an increased risk of severe OHSS in the long GnRH agonist group compared with the short GnRH antagonist protocol. WHAT IS KNOWN ALREADY?: In the most recent Cochrane review, the GnRH antagonist protocol was associated with a similar live birth rate (LBR), a similar on-going pregnancy rate (OPR), and a lower incidence of OHSS (odds ratio (OR) = 0.43 95% confidence interval (CI): 0.33-0.57) compared with the traditional GnRH agonist protocol. Previous trials comparing the two protocols mainly included selected patient populations, a limited number of patients and the applied OHSS criteria differed, making direct comparisons difficult. In two recent large meta-analyses, no significant differences in LBR (OR = 0.86; 95% CI: 0.72-1.02) or in the incidence of severe OHSS were reported, while others found a lower LBR (OR = 0.82; 95% CI: 0.68-0.97) and a reduced risk of severe OHSS using the GnRH antagonist protocol (OR = 0.60; 95% CI: 0.40-0.88). STUDY DESIGN, SIZE, DURATION Phase IV, dual-centre, open-label, RCT including 1050 women allocated to either short GnRH antagonist or long GnRH agonist protocol in a 1:1 ratio and enrolled over a 5-year period using a web-based concealed randomization code. This is a superiority study designed to detect a difference in severe OHSS, the primary outcome, between the two groups with a power of 80% and stratified for age, assisted reproductive technology (ART) clinic and planned fertilization procedure (IVF/ICSI). The secondary aims were to compare rates of mild and moderate OHSS, positive plasma (p)-hCG, on-going pregnancy and live birth between the two arms. None of the women had undergone previous ART treatment. PARTICIPANTS/MATERIALS, SETTING, METHODS All infertile women referred for their first IVF/ICSI at two public fertility clinics, less than 40 years of age and with no uterine malformations were asked to participate. A total of 1099 subjects were randomized, including women with poor ovarian reserve, polycystic ovary syndrome and irregular cycles. A total of 49 women withdrew their consent, thus 1050 subjects were allocated to the GnRH antagonist (n = 534) and agonist protocol (n = 516), respectively. In total 1023 women started recombinant human follitropin-β (rFSH) stimulation, 528 in the GnRH antagonist group and 495 in the GnRH agonist group. All subjects were given a fixed rFSH dose of 150 IU or 225 IU according to age ≤36 years or >36 years, with the option to adjust dose at stimulation day 6. Clinical OHSS parameters were collected at oocyte retrieval, and Days 3 and 14 post-transfer. On-going pregnancy was determined by transvaginal ultrasonography at gestational weeks 7-9. In the intention-to-treat (ITT) analysis for reproductive outcomes, 1050 subjects were included. For the ITT analyses on OHSS 1023 subjects who started gonadotrophin stimulation were included. MAIN RESULTS AND THE ROLE OF CHANCE The incidence of severe OHSS [5.1% (27/528) versus 8.9% (44/495) (difference in proportion percentage point (Δpp) = -3.8pp; 95% CI: -7.1 to -0.4; P = 0.02)] and moderate OHSS [10.2% (54/528) versus 15.6% (77/495) (Δpp = -5.3pp; 95% CI: -9.6 to -1.0; P = 0.01) ] was significantly lower in the GnRH antagonist group compared with the agonist group, respectively. In the GnRH antagonist and agonist group, respectively, 4.7% (25/528) versus 8.5% (42/495) women were seen by a physician due to OHSS (P = 0.01), and 1.7% (9/528) versus 3.6% (18/495) were admitted to hospital due to OHSS (P = 0.06). No women had ascites-puncture in the GnRH antagonist group versus 2.0% (10/495) in the GnRH agonist group (P < 0.01). LBRs were 22.8% (122/534) versus 23.8% (123/516) (Δpp = -1.0pp; 95% CI: -6.3 to 4.3; P = 0.70) and OPRs were 24.9% (133/528) versus 26.2% (135/516) (Δpp = -1.3pp; 95% CI: -6.7 to 4.2; P = 0.64) per randomized subject in the GnRH antagonist versus agonist group, with a mean number of 1.1 versus 1.2 embryos transferred in the two groups. Pregnancy rates (PR) per randomized subject, per started gonadotrophin stimulation and per embryo transfer were all similar in the two groups. LIMITATIONS, REASONS FOR CAUTION A possible limitation is the duration of the trial, with new methods, such as 'freeze all' and 'GnRH agonist triggering', being developed during the trial, the new methods were sought avoided, however a total number of 32 women had 'freeze all' and 'GnRH agonist triggering' was performed in three cases. Ultrasonic measurements were performed by different physicians and inter-observer bias may be present. Measures of anti-Mullerian hormone and antral follicle count, to estimate ovarian reserve and thus predict risk of OHSS, were not performed. Finally, the physicians were not blinded to GnRH treatment group after randomization. WIDER IMPLICATIONS OF THE FINDINGS The short GnRH antagonist protocol should be the protocol of choice for patients undergoing their first ART cycle in females <40 years of age including both low and high responders when an age-dependent initially fixed gonadotrophin dose is used, as an increased risk of severe OHSS and the associated complications is seen in the long GnRH agonist group and as PRs and LBRs are similar in the two groups. Patients at risk of OHSS particularly benefit from the short GnRH antagonist treatment as GnRH agonist triggering can be used.

Gonadotropin-releasing hormone agonist trigger in oocyte donors co-treated with a gonadotropin-releasing hormone antagonist: a dose-finding study. Fertil Steril 2015; 105:356-63. [PMID: 26523330 DOI: 10.1016/j.fertnstert.2015.10.014] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2015] [Revised: 10/07/2015] [Accepted: 10/13/2015] [Indexed: 10/22/2022]
Abstract
OBJECTIVE To determine the optimal GnRH agonist dose for triggering of oocyte maturation in oocyte donors. DESIGN Single-center, randomized, parallel, investigator-blinded trial. SETTING IVFMD, My Duc Hospital, Ho Chi Minh City, Vietnam. PATIENT(S) One hundred sixty-five oocyte donors (aged 18-35 years, body mass index [BMI] <28 kg/m(2), antimüllerian hormone level >1.25 ng/mL, and antral follicle count ≥6). INTERVENTION(S) Ovulation trigger with 0.2, 0.3, or 0.4 mg triptorelin in a GnRH antagonist cycle. MAIN OUTCOME MEASURE(S) The primary end point was number of metaphase II oocytes. Secondary end points were fertilization and cleavage rates, number of embryos and top-quality embryos, steroid levels, ovarian volume, and ongoing pregnancy rate (PR) in recipients. RESULT(S) There were no significant differences between the triptorelin 0.2, 0.3, and 0.4 mg trigger groups with respect to number of metaphase II oocytes (16.0 ± 8.5, 15.9 ± 7.8, and 14.7 ± 8.4, respectively), embryos (13.2 ± 7.8, 11.7 ± 6.9, 11.8 ± 7.0), and number of top-quality embryos (3.8 ± 2.9, 3.6 ± 3.0, 4.1 ± 3.0). Luteinizing hormone levels at 24 hours and 36 hours after trigger was significantly higher with triptorelin 0.4 mg versus 0.2 mg and 0.3 mg (9.8 ± 7.1 IU/L vs. 7.3 ± 4.1 IU/L and 7.2 ± 3.7 IU/L, respectively; 4.6 ± 3.2 IU/L vs. 3.2 ± 2.3 IU/L and 3.3 ± 2.1 IU/L, respectively. Progesterone level at oocyte pick-up +6 days was significantly higher in the 0.4-mg group (2.2 ± 3.7 ng/ml) versus 0.2 mg (1.1 ± 1.0 ng/ml) and 0.3 mg (1.2 ± 1.6 ng/ml). One patient developed early-onset severe ovarian hyperstimulation syndrome (OHSS). CONCLUSION(S) No significant differences between triptorelin doses of 0.2, 0.3, and 0.4 mg used for ovulation trigger in oocyte donors were seen with regard to the number of mature oocytes and top-quality embryos. CLINICAL TRIAL REGISTRATION NUMBER NCT02208986.
