Abstract
The purpose of this article is to explore the relationship between the total dose of follicle-stimulating hormone (FSH) applied during controlled ovulation stimulation and the live birth rates (LBRs) in non-PCOS population. Many studies have found no difference between the dose of FSH application and pregnancy outcomes such as clinical pregnancy rates after fresh embryo transfer. However, a recent large retrospective analysis found a negative correlation between live birth rates and increasing dose of FSH. It is still controversial about the association between FSH dose and LBRs. In addition, no studies have yet explored the nonlinear relationship between FSH and LBRs. This cohort study included a total of 11,645 patients who had accepted IVF/intracytoplasmic sperm injection (ICSI) at the second hospital of Hebei medical university between December 2014 to December 2019. PCOS was identified by Rotterdam PCOS criteria. We researched the association between FSH total dose and live birth rates (LBRs) using multivariate regression analysis. In addition, a model for nonlinear relationships based on a two-part linear regression was applied. The analysis of threshold effects indicated that LBR increased with every 1000 IU FSH when the concentration of FSH was lower than 1410 IU (OR 1.55, 95% CI [1.05, 2.28]); however, a negative association between FSH dose and LBR (OR 0.94, 95% CI [0.89, 0.99]) was found when the FSH total dose was higher than 1410 IU. It is worth noting that the relationship between LBR and FSH dose varied among patients of different ages (OR 0.92 vs 1.06, P for interaction < 0.05).

Front Endocrinol (Lausanne) 2023; 14:1249625. [PMID: 38033995 PMCID: PMC10682729 DOI: 10.3389/fendo.2023.1249625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 10/30/2023] [Indexed: 12/02/2023] Open
Abstract
Objective The purpose of this study was to evaluate the cumulative live birth rate (CLBR) of mild stimulation and conventional stimulation for the low-prognosis population undergoing PPOS protocols. Methods This was a retrospective cohort study. We included women with a low prognosis. All women underwent PPOS protocols, and the starting gonadotropin (Gn) dose was 150 IU or 300 IU. The primary outcome measure was CLBR. The secondary outcome measures were the number of oocytes retrieved, number of 2PN oocytes and number of available embryos. Results In total, 171 women with mild stimulation and 1810 women with conventional stimulation met the criteria. In the PSM model, 171 mild stimulation cycles were matched with 513 conventional stimulation cycles. The gonadotropin dosage in the mild stimulation group was significantly lower than that in the conventional stimulation group (1878.6 ± 1065.7 vs. 2854.7 ± 821.0, P<0.001). The numbers of oocytes retrieved, 2PN oocytes, available embryos and high-quality embryos were also higher in the conventional stimulation group than in the mild stimulation group (P<0.05). There was no significant between-group difference in the cumulative clinical pregnancy rate (26.3% vs. 27.5%, P=0.77). The CLBR after mild stimulation was similar to that after conventional stimulation (21.1% vs. 22.0%, P=0.79). Conclusion In our study, we found that the CLBRs of mild stimulation and conventional stimulation were similar, despite conventional stimulation resulting in significantly more oocytes and embryos. Thus, mild stimulation can be considered an option for women with a low prognosis in PPOS protocols.

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.

The putative roles of FSH and AMH in the regulation of oocyte developmental competence: from fertility prognosis to mechanisms underlying age-related subfertility. Hum Reprod Update 2021; 28:232-254. [PMID: 34969065 DOI: 10.1093/humupd/dmab044] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 11/18/2021] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Fertility loss during female ageing is associated with increasing basal FSH and decreasing anti-Müllerian hormone (AMH) concentrations, together with compromised oocyte quality, presumably due to increased oxidative stress (OS) and DNA damage, as well as reduced metabolic and meiotic competences. Basal FSH and AMH circulatory concentrations have been broadly utilized as IVF success predictors, regardless of fluctuations in prognostic accuracy; basal FSH and AMH perform better in pre-advanced maternal age (AMA: >35 years) and AMA patients, respectively. The relationships between FSH and AMH intrafollicular levels and IVF outcomes suggest, nevertheless, that both hormones regulate oocyte competence, supporting the hypothesis that changes in FSH/AMH levels cause, at least in part, oocyte quality degradation during ageing. To understand the reasons behind the fluctuations in FSH and AMH prognostic accuracies and to clarify their participation in mechanisms determining oocyte competence and age-related subfertility, a deeper knowledge of the regulation of FSH and AMH intrafollicular signalling during the female reproductive lifespan, and of their effects on the cumulus-oocyte complex, is required. OBJECTIVE AND RATIONALE An extensive body of information on the regulation of FSH and AMH intrafollicular availability and signalling, as well as on the control of folliculogenesis and oocyte metabolism, has been accumulated. However, these datasets have been explored within the relatively narrow boundaries of their specific subjects. Given the aforementioned gaps in knowledge and their clinical relevance, herein we integrate clinical and basic data, within a wide biological perspective, aiming to shed light on (i) the reasons for the variability in the accuracy of serum FSH and AMH as fertility markers, and on (ii) the potential roles of these hormones in mechanisms regulating oocyte quality, particularly those associated with ageing. SEARCH METHODS The PubMed database encompassing the period between 1960 and 2021 was searched. Principal search terms were FSH, FSH receptor, AMH, oocyte, maternal age, cumulus, transzonal projections (TZPs), actin, OS, redox, reactive oxygen species, mitochondria, DNA damage, DNA repair, aneuploidy, spindle, meiosis, gene expression, transcription, translation, oocyte secreted factors (OSFs), cAMP, cyclic guanosine monophosphate, natriuretic peptide C, growth differentiation factor 9, bone morphogenetic protein 15 and fibroblast growth factor. OUTCOMES Our analysis suggests that variations in the accuracy of fertility prognosis reflect a modest association between circulatory AMH levels and oocyte quality as well as increasing basal FSH inter-cycle variability with age. In addition, the basic and clinical data articulated herein support the hypothesis that increased intrafollicular FSH levels, as maternal age advances, may override the physiological protective influences of AMH and OSFs against excessive FSH signalling in cumulus cells. This would result in the disruption of oocyte homeostasis via reduced TZP-mediated transfer of cumulus-derived molecules essential for meiotic competence, gene expression, redox activity and DNA repair. WIDER IMPLICATIONS In-depth data analysis, encompassing a wide biological perspective has revealed potential causative mechanisms of age-related subfertility triggered by alterations in FSH/AMH signalling during the female reproductive life. Insights from new mechanistic models arising from this analysis should contribute to advancing our comprehension of oocyte biology in humans and serve as a valuable reference for novel AMA subfertility treatments aimed at improving oocyte quality through the modulation of AMH/FSH action.

Abstract
Selective LH deficiency has been described in several men, but only in two women who presented normal pubertal development but secondary amenorrhoea due to anovulation. Despite its rarity, this condition represents a valuable model for studying the processes regulated by FSH or LH during late folliculogenesis and ovulation in humans. A woman previously diagnosed with selective LH deficiency due to a homozygous germline splice site mutation in LHB (IVS2 + 1G→C mutation) was submitted to an individualised ovarian induction protocol, first with recombinant LH and then with highly purified urinary hCG. Ovarian follicle growth and ovulation were achieved, and a healthy baby was born after an uneventful term pregnancy. The treatment described herein demonstrates that the clinical actions of exogenous LH or hCG in inducing late-stage follicular development in women with deficient LH production or performance might be interchangeable or inevitable, once FSH-dependent early follicular growth is assured.

Fresh and cumulative live birth rates in mild versus conventional stimulation for IVF cycles in poor ovarian responders: a systematic review and meta-analysis. Hum Reprod Open 2021; 2021:hoaa066. [PMID: 33614987 PMCID: PMC7882043 DOI: 10.1093/hropen/hoaa066] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Revised: 11/16/2020] [Indexed: 12/19/2022] Open
Abstract
STUDY QUESTION Are cumulative and live birth rates (LBRs) comparable in poor ovarian response women treated with different protocols of mild stimulation IVF (i.e. oral compounds, lower doses or shorter treatments) versus conventional IVF? SUMMARY ANSWER Mild ovarian stimulation (MOS) results in comparable outcomes to those of conventional stimulation in poor ovarian response patients with low ovarian reserve. WHAT IS KNOWN ALREADY Several randomized trials and meta-analyses have been published evaluating the role of mild (MOS) versus conventional ovarian stimulation in poor ovarian response patients. Most report a potentially higher safety profile, patient satisfaction and lower costs, suggesting that the higher cycle cancellation rate and fewer oocytes retrieved following MOS does not affect the final reproductive outcome. Additionally, over the last few years, new publications have added data regarding MOS, and shown the possible benefit of a higher oocyte yield which may also improve prognosis in patients with poor ovarian response. STUDY DESIGN SIZE DURATION We conducted a systematic search of relevant randomized controlled trials (RCTs). We searched electronic databases, including MEDLINE, EMBASE, LILACS-BIREME, CINAHL, The Cochrane Library, CENTRAL (Cochrane Register), Web of Science, Scopus, Trip Database and Open Grey, to identify all relevant studies published up to March 2020. We examined trial registries for ongoing trials. No publication-year or language restrictions were adopted. We explored the reference list of all included studies, reviews and abstracts of major scientific meetings. The primary outcomes were cumulative and fresh LBR (CLBR and FLBR) per woman randomized. PARTICIPANTS/MATERIALS SETTING METHODS We included subfertile women undergoing IVF/ICSI characterized as poor responders and compared primary and secondary outcomes between the different protocols of mild stimulation IVF (i.e. oral compounds, lower doses or shorter treatments) and conventional IVF. We used the PICO (Patients, Intervention, Comparison and Outcomes) model to select our study population. MAIN RESULTS AND THE ROLE OF CHANCE Overall, 15 RCTs were included in the meta-analysis. CLBR and FLBR were comparable between mild versus conventional stimulation (RR 1.15; 95% CI: 0.73 - 1.81; I2 = 0%, n = 424, moderate certainty and RR 1.01; 95% CI: 0.97 - 1.04; I 2 = 0%, n = 1001, low certainty, respectively). No difference was observed either when utilizing oral compounds (i.e. letrozole and clomiphene) or lower doses. Similarly, ongoing pregnancy rate (OPR) and clinical pregnancy rate (CPR) were equivalent when comparing the two groups (RR 1.01; 95% CI: 0.98 - 1.05; I 2 = 0%, n = 1480, low certainty, and RR 1.00; 95% CI: 0.97 - 1.03; I2 = 0%, n = 2355, low certainty, respectively). A significantly lower oocyte yield (mean differences (MD) -0.80; 95% CI: -1.28, -0.32; I2 = 83%, n = 2516, very low certainty) and higher rate of cycle cancellation (RR 1.48; 95% CI: 1.08 - 2.02; I2 = 62%, n = 2588, low certainty) was observed in the MOS group. LIMITATIONS REASONS FOR CAUTION The overall quality of the included studies was low to moderate. Even though strict inclusion criteria were used, the selected studies were heterogeneous in population characteristics and treatment protocols. We found no differences in CLBR between MOS and COS (95% CI: 0.73 - 1.81.). WIDER IMPLICATIONS OF THE FINDINGS MOS could be considered as a treatment option in low prognosis poor responder patients, given that it results in similar fresh and CLBRs compared with COS. A milder approach is associated with a lower number of oocytes retrieved and a higher cancellation rate, although treatment cost is significantly reduced. Future research should focus on which type of ovarian stimulation may be of benefit in better prognosis women. STUDY FUNDING/COMPETING INTERESTS There were no sources of financial support.

Abstract
Immunohistochemical staining is the important method for the identification of protein expression in mammal ovaries, in particular in the follicles with the potential to develop into cumulus-oocyte complexes (COCs), which are able to support oocyte maturation regardless of in vivo or in vitro. Here, we reported an advanced immunohistochemical method based on an artificial structure gathering multiple COCs by paraffin embedding for rapid and highly sensitive detection of co-expressed proteins in ovine COCs rather than ovaries. Compared with the conventional immunohistochemistry on ovine ovaries, the advanced COC paraffin sectioning technique showed the better immunostaining effect and featured the higher generation rate for COCs, the distincter cumulus layers, and the more simplified procedures. These results indicate that the COC paraffin sectioning technique is highly effectively applied for identification of protein expression in ovine COC.

Abstract
BACKGROUND Despite great advances in assisted reproductive technology, poor ovarian response (POR) is still considered as one of the most challenging tasks in reproductive medicine. OBJECTIVE AND RATIONALE The aim of this systemic review is to evaluate the role of different adjuvant treatment strategies on the probability of pregnancy achievement in poor responders undergoing IVF. Randomized controlled trials (RCTs) comparing 10 adjuvant treatments [testosterone, dehydroepiandrosterone (DHEA), letrozole, recombinant LH, recombinant hCG, oestradiol, clomiphene citrate, progesterone, growth hormone (GH) and coenzyme Q10 (CoQ10)] were included. SEARCH METHODS Relevant studies published in the English language were comprehensively selected using PubMed, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL) until 11 July 2018. We included studies that investigated various adjuvant agents, including androgen and androgen-modulating agents, oestrogen, progesterone, clomiphene citrate, GH and CoQ10, during IVF treatment and reported subsequent pregnancy outcomes. The administration of GnRH analogs and gonadotrophins without adjuvant treatment was set as the control. We measured study quality based on the methodology and categories listed in the Cochrane Collaboration Handbook. This review protocol was registered with PROSPERO (CRD42018086217). OUTCOMES Of the 1124 studies initially identified, 46 trials reporting on 6312 women were included in this systematic review, while 19 trials defining POR using the Bologna criteria reporting 2677 women were included in the network meta-analysis. Compared with controls, DHEA and CoQ10 treatments resulted in a significantly higher chance of clinical pregnancy [odds ratio (OR) 2.46, 95% CI 1.16 to 5.23; 2.22, 1.08-4.58, respectively]. With regard to the number of retrieved oocytes, HCG, oestradiol and GH treatments had the highest number of oocytes retrieved [weighted mean difference (WMD) 2.08, 0.72 to 3.44; 2.02, 0.23 to 3.81; 1.72, 0.98 to 2.46, compared with controls, respectively]. With regard to the number of embryos transferred, testosterone and GH treatment led to the highest number of embryos transferred (WMD 0.72, 0.11 to 1.33; 0.67, 0.43 to 0.92; compared with controls, respectively). Moreover, GH resulted in the highest oestradiol level on the HCG day (WMD 797.63, 466.45 to 1128.81, compared with controls). Clomiphene citrate, letrozole and GH groups used the lowest dosages of gonadotrophins for ovarian stimulation (WMD 1760.00, -2890.55 to -629.45; -1110.17, -1753.37 to -466.96; -875.91, -1433.29 to -282.52; compared with controls, respectively). CoQ10 led to the lowest global cancelation rate (OR 0.33, 0.15 to 0.74, compared with controls). WIDER IMPLICATIONS For patients with POR, controlled ovarian stimulation protocols using adjuvant treatment with DHEA, CoQ10 and GH showed better clinical outcomes in terms of achieving pregnancy, and a lower dosage of gonadotrophin required for ovulation induction. Furthermore, high-level RCT studies using uniform standards for POR need to be incorporated into future meta-analyses.

Ezoe K, Ni X, Kobayashi T, Kato K. Anti-Müllerian hormone is correlated with cumulative live birth in minimal ovarian stimulation with clomiphene citrate: a retrospective cohort study. BMC Pregnancy Childbirth 2020; 20:740. [PMID: 33246461 PMCID: PMC7694423 DOI: 10.1186/s12884-020-03446-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 11/20/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Several studies have investigated the correlation between the serum anti-Müllerian hormone (AMH) level and in vitro fertilization (IVF) outcomes in controlled ovarian stimulation cycles; however, studies regarding the correlation of the serum AMH level with IVF outcomes in minimal ovarian stimulation cycles remain limited. In this study, we aimed to analyze the correlation of the serum AMH level with ovarian responsiveness, embryonic outcomes, and cumulative live birth rates in clomiphene citrate (CC)-based minimal ovarian stimulation cycles. METHODS Clinical records of 689 women whose entire ovarian stimulation regimen consisted solely of minimal stimulation cycle IVF using CC alone from November 2017 to October 2019 were retrospectively reviewed. The association between IVF outcomes and the serum AMH level before the initiation of the first fertility treatment was analyzed. Furthermore, the correlation of the serum AMH level with cumulative live birth rates after IVF treatment was assessed. The Cochran-Armitage test, Pearson's chi-squared test, Spearman rank correlation test, Student's t-test, one-way analysis of variance, logistic regression analysis, Kaplan-Meier method and Cox proportional hazards model were used to analyze the data. RESULTS The serum AMH level positively correlated with the number of retrieved oocytes, blastocyst formation rate, blastocyst cryopreservation rate, and live birth rate per oocyte retrieval in CC-based minimal ovarian stimulation cycles without any exogenous gonadotropin administration. Furthermore, the cumulative live birth rate and treatment period required for conceiving were strongly associated with the serum AMH level at the initiation of fertility treatment. CONCLUSIONS A low serum AMH level correlated with low ovarian responsiveness, impaired pre-implantation embryonic development, and decreased cumulative live birth rate in CC-based minimal ovarian stimulation cycles. Therefore, the cycle success rate would be predicted by measuring the serum AMH level in minimal ovarian stimulation with CC alone.

Abstract
The aim of our study was to assess the value of serum AMH in prediction of metaphase II oocytes in poor responders. We performed a prospective cohort study included 206 poor responders candidate for ICSI using antagonist protocol. They were classified into 3 groups. Group I included 50 women with AMH < 0.3 ng/ml, group II included 85 women with AMH 0.3-0.7 ng/ml and group III included 71 women with AMH > 0.7-1.0 ng/ml. The primary outcome parameter was the number of MII oocytes. There was a highly significant difference between the study groups regarding E2 at triggering (481.41 ± 222.653, 648.17 ± 264.353 and 728.74 ± 305.412 respectively, number of oocyte retrieved (2.37 ± 1.178, 3.38 ± 1.622 and 3.80 ± 1.427 respectively), number of MII oocytes (1.66 ± 1.039, 2.35 ± 1.171 and 2.61 ± 1.080 respectively), number of fertilized oocytes (1.39 ± 0.919, 1.91 ± 0.983 and 2.21 ± 0.937 respectively), , total number of embryos (1.34 ± 0.938, 1.76 ± 0.956 and 2.09 ± 0.907 respectively), clinical pregnancy rates (4.9 vs. 7.7 and 19.7% respectively). We concluded that AMH is a good predictor for number of MII oocytes in poor responders undergoing ICSI.

A prospective randomized trial comparing corifollitropin-α late-start (day 4) versus standard administration (day 2) in expected poor, normal, and high responders undergoing controlled ovarian stimulation for IVF. J Assist Reprod Genet 2020; 37:1163-1170. [PMID: 32185595 DOI: 10.1007/s10815-020-01742-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Accepted: 03/06/2020] [Indexed: 10/24/2022] Open
Abstract
OBJECTIVE To assess whether corifollitropin-α (CFα) late-start administration (day 4) and standard administration (day 2) can obtain similar oocyte yield and live birth rate. STUDY DESIGN A randomized controlled trial. SETTING University Hospital IVF Unit. PATIENTS One hundred thirteen women undergoing IVF. INTERVENTIONS Patients distributed in three subgroups (expected poor, normal, or high responders to FSH) were randomized into two treatment arms: (a) CFα late-start: CFα on day 4 + GnRH antagonist from day 8 + (when needed) recFSH from day 11; (b) CFα standard start: CFα on day 2 + GnRH antagonist from day 6 + (when needed) recFSH from day 9. IVF or ICSI was performed as indicated. RESULTS Considering the whole study group, the late-start regimen obtained comparable oocyte yield (8.9 ± 5.6 vs. 8.8 ± 6.2; p = n.s.), cPR/started cycle (25% vs. 31.6%, p = n.s.), and cumulative live birth rate (LBR)/ovum pickup (OPU) (29.2% vs. 37.7%, p = n.s.) than the standard regimen. The outcome of the two regimens was comparable in the two subgroups of high and normal responders. Differently, in poor responders, oocyte yield was similar, but LBR/OPU was significantly lower with late-start CFα administration that caused 40% cancellation rate due to monofollicular response. ROC curves showed that the threshold AMH levels associated with cycle cancellation were 0.6 ng/ml for late-start regimen and 0.2 ng/ml for standard regimen. CONCLUSION CFα may be administered on either day 2 or day 4 to patients with expected high or normal response to FSH without compromising oocyte yield and/or live birth rate. Differently, late-start administration is not advisable for expected poor responders with AMH ≤ 0.6 ng/ml. TRIAL REGISTRATION NCT03816670.

Abstract
PURPOSE To determine age-adjusted overall success rates for patients undergoing clomiphene citrate only minimal stimulation cycle (mini) in vitro fertilization (IVF) without any gonadotropin administration. METHODS Eight hundred thirty-nine women (mean age: 38.4 ± 0.1 years; 2488 cycles) underwent clomiphene citrate only mini-IVF. Their first oocyte retrieval was between January 2009 and December 2009, with follow-up until December 2014. The cumulative live birth rate (CLBR) per oocyte retrieval cycle started and live birth rate per oocyte was retrospectively analyzed. The basic CLBR was calculated as the number of women who achieved a live birth divided by the total number of women who started oocyte retrieval. RESULTS The mean number of oocytes retrieved was 1.5. The basic CLBRs for all ages after the first and third cycles were 22.6% and 39.2%, respectively. For ≤ 34 years, 35-37 years, 38-40 years, 41-42 years, and ≥ 43 years, CLBRs after the first and third cycles were 42.5% and 70.1%, 32.9% and 49.1%, 20.0% and 38.6%, 12.6% and 25.2%, and 4.4% and 8.8%, respectively. These rates had a significant relationship with age (P < 0.01). The LBR per oocyte for all ages was 9.6%. CONCLUSION Acceptable overall IVF success rates can be achieved in clomiphene citrate only mini-IVF, as well as acceptable LBR. The CLBRs and LBRs per oocyte are evidently influenced by women's age.

CELL JOURNAL 2019; 22:55-59. [PMID: 31606966 PMCID: PMC6791063 DOI: 10.22074/cellj.2020.6525] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/05/2018] [Accepted: 03/02/2019] [Indexed: 11/07/2022]
Abstract
Objective The aim of this blind randomised clinical trial study was to assess the clinical efficiency of combined
density gradient centrifugation/Zeta (DGC/Zeta) sperm selection procedure compared to conventional DGC in infertile
men candidates for intracytoplasmic sperm injection (ICSI). The literature shows that DGC/Zeta is more effective
compared to DGC alone in selection of sperms with normal chromatin and improves the clinical outcome of the ICSI
procedure. Therefore, this study re-evaluates the efficiency of DGC/Zeta in improving the clinical outcomes of ICSI in
an independent clinical setting.
Materials and Methods In this randomized, single-blind, clinical trial, a total of 240 couples with male factor infertility
and at least one abnormal sperm parameter were informed regarding the study and 220 participated. Based on inclusion
and exclusion criteria, 103 and 102 couples were randomly allocated into the DGC/Zeta and DGC groups, respectively.
ICSI outcomes were followed and compared between the two groups.
Results Although there was no significant difference in fertilization rate (P=0.67) between the DGC/Zeta and DGC
groups, mean percentage of good embryo quality (P=0.04), good blastocysts quality (P=0.049), expanded blastocysts
(P=0.007), chemical pregnancies (P=0.005) and clinical pregnancies (P=0.007) were significantly higher in the DGC/
Zeta group compared to DGC. In addition, implantation rate was insignificantly higher in DGC/Zeta compared to DGC
(P=0.17).
Conclusion This is the second independent study showing combined DGC/Zeta procedure improves ICSI outcomes,
especially the pregnancy rate, compared to the classical DGC procedure and this is likely related to the improved quality of
sperm selected by the DGC/Zeta procedure (Registration number: IRCT20180628040270N1).

Abstract
PURPOSE To evaluate the effect of double stimulations during the follicular and luteal phases in women with poor ovarian response (POR) in in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. BASIC PROCEDURES This prospective clinical study was performed in Royan Institute from October 2014 to January 2016. 121 patients were diagnosed as POR on the basis of Bologna criteria were included. Double stimulations were performed during the follicular and luteal phases by Letrozole, Clomid, hMG and GnRH-agonist. The patients' present cycle outcomes were compared with those of the previous cycle results using appropriate statistical tests. MAIN FINDING The total of 104 (85.9%) patients completed the stimulation stages. The analysis revealed the number of retrieved oocytes after the first and second stimulations did not differ (P = 0.2); however, the fertilization rate and the number of frozen embryos after the first stimulation were significantly higher than those of in the second stimulation (P < 0.001 and P = 0.03), indicating the better quality of retrieved oocytes after the first stimulation. The mean number of MII oocytes and the fertilization rate after Shanghai protocol were higher than those of the previous antagonist protocol with a substantial trend toward significance (P = 0.06), which can be clinically important. The cancellation rate (33%) due to no ovarian response and no embryo formation was still high in these patients. PRINCIPAL CONCLUSION Since the intensity of stimulation in both stages was mild, this protocol can be considered a time-efficient and patient friendly regime; however, more studies are required with emphasis on its cost-effectiveness.

Abstract
BACKGROUND Letrozole is widely employed as ovulation induction agent in women with PCOS, but its use in mild stimulation (MS) protocols for IVF is limited. Aim of the present study was to evaluate the feasibility of a MS protocol with letrozole plus hMG in non-obese PCOS women undergoing IVF after a metformin pre-treatment. METHODS We retrospectively evaluated the data of 125 non-obese PCOS undergoing MS with letrozole plus hMG, 150 IU as starting dose, (group 1, N = 80) compared to those undergoing a conventional IVF stimulation protocols (CS) (group 2, N = 45) prior to IVF. All patients had received metformin extended release 1200-2000 mg daily for three to six months before IVF. GnRH antagonist was administered in both groups when the leading follicles reached 14 mm. RESULTS Both groups were comparable for age, BMI and ovarian reserve markers. Both groups showed lower than expected AFC and AMH values as a consequence of metformin pre-treatment. Letrozole-treated patients required a significantly lower amount of gonadotropins units (p < 0.0001), and showed significantly lower day 5, day 8 and hCG day E2 levels compared to patients undergoing the CS protocol (p < 0.0001, p < 0.0001 and p = 0.001 respectively). The oocyte yield, in terms of total (6, IQR 3, vs 6, IQR 4 respectively,) and MII oocytes (5, IQR 3, vs 5, IQR 3, respectively) number, did not differ among groups; the number of total (3, IQR 2, vs 3, IQR 1 respectively) and good quality embryos (2, IQR1 vs 2, IQR 1,5 respectively) obtained was comparable as well in the two groups. The number of fresh transfers was significantly higher in group 1 compared to group 2 (80% vs 60%, p = 0.016). A trend for higher cumulative clinical pregnancy rate was found in women undergoing MS compared to CS (42.5%vs 24,4%, p = 0.044), but the study was not powered to detect this difference. CONCLUSIONS The present study suggests that the use of letrozole as adjuvant treatment to MS protocols for IVF may be an effective alternative to CS protocols for non-obese PCOS patients pre-treated with metformin, as it provides comparable IVF outcome without requiring high FSH dose, and avoiding supraphysiological estradiol levels.

Abstract
Objective To compare the efficacy of three protocols for ovarian stimulation in patients with diminished ovarian reserve during in vitro fertilization (IVF) treatment. Methods This prospective randomized study enrolled patients with diminished ovarian reserve who underwent cycles of IVF or intracytoplasmic sperm injection. The patients were randomly divided into three groups: a modified gonadotrophin releasing hormone (GnRH) agonist protocol (group A); (ii) a mild stimulation protocol (group B); or (iii) an antagonist protocol (group C). Demographic characteristics, clinical variables and pregnancy outcomes were compared between the groups. Results A total of 116 patients were enrolled in the study: 54 in group A, 52 in group B and 60 in group C. Group B (32.69%) had a significantly higher cycle cancellation rate compared with groups A (11.11%) and C (16.67%). The early abortion rate of group C (44.44%) was significantly higher than group A (12.50%), but not significantly different from group B (16.67%). There were no significant differences in the clinical pregnancy rates and live birth rates among the three groups. Conclusion A modified GnRH agonist protocol achieved a comparable pregnancy rate to those of the mild stimulation protocol and antagonist protocol, whilst having lower cycle cancellation and early abortion rates.

Abstract
A societal preference of delaying maternal age at first childbirth has increased reliance on assisted reproductive technologies/therapies (ART) to conceive a child. Oocytes that have undergone physiologic aging (≥35 years for humans) are now commonly used for ART, yet evidence is building that suboptimal reproductive environments associated with aging negatively affect oocyte competence and embryo development-although the mechanisms underlying these relationship are not yet well understood. Epigenetic programming of the oocyte occurs during its growth within a follicle, so the ovarian stimulation protocols that administer exogenous hormones, as part of the first step for all ART procedures, may prevent the gamete from establishing an appropriate epigenetic state. Therefore, understanding how oocyte. Therefore, understanding how hormone stimulation and oocyte physiologic age independently and synergistically physiologic age independently and synergistically affect the epigenetic programming of these gametes, and how this may affect their developmental competence, are crucial to improved ART outcomes. Here, we review studies that measured the developmental outcomes affected by superovulation and aging, focusing on how the epigenome (i.e., global and imprinted DNA methylation, histone modifications, and epigenetic modifiers) of gametes and embryos acquired from females undergoing physiologic aging and exogenous ovarian stimulation is affected.

Abstract
Abstract: Objective: To determine the efficacy of clomiphene citrate (CC) in preventing luteinizing hormone (LH) surge without adding gonadotropin releasing hormone (GnRH) antagonist or GnRH agonist in stimulated first fresh intracytoplasmic sperm injection cycle by evaluating the outcome of oocytes and embryo quality. Design: Registry cohort study. Settings: Fertility Clinic Registry at Hospital University Kebangsaan Malaysia. Patients: A total of 235 fresh stimulated ICSI cycle for patients aged 18-40 years old using clomiphene citrate plus gonadotropin (n = 117) and GnRH antagonist plus gonadotropin (n = 118) were studied. Intervention: Comparing two different ovarian stimulation protocol. Main outcome measure(s): Social economical demographic, ovarian stimulation response and laboratory outcome. Fertilization rate as our primary outcome and our secondary outcome were oocyte retrieval rate, mature oocyte rate and top quality embryo rate. Result(s):There were no difference in the demographic and hormonal characteristic of the study groups. The primary outcome of fertilization rate has significant difference with p value of 0.003; 73.2% for CC group and 64.2% for GnRH antagonist group. The secondary outcome of OR rate (78.4% ± 17.6% VS 80.3% ± 13.4%, p = 0.368), mature oocyte rate (85.2% ± 19.0 VS 81.7% ± 16.7%, p = 0.130) and top quality embryo rate (79.4% ± 24.2% VS 74.9% ± 22.9%, p = 0.178) were comparable between both groups. There were significant difference between the endometrial thickness on the day of trigger and OHSS risk among both groups (8.5 mm ± 1.0 mm VS 9.4 mm ± 1.1 mm, p < 0.001 and 12.8% VS 44.1% respectively). Discussion: Minimal stimulation protocol with CC and gonadotropin may be the answer to many infertile couples in need of IVF and yet having financial situation deterring them in attempting IVF treatment. GnRH antagonist could be safely replaced by CC by extending to 10 days as this protocol gives better primary outcome and comparable secondary outcomes with less OHSS. CC is recognized to induce thinning of endometrial lining and thus, may impair embryo implantation. However, with advancement of the vitrification system and higher success rate in frozen-thaw embryo transfer worldwide provides an excellent solution for this issue.

Abstract
BACKGROUND Gonadotropins are the most commonly used medications for controlled ovarian stimulation in in vitro fertilisation (IVF). However, they are expensive and invasive, and are associated with the risk of ovarian hyperstimulation syndrome (OHSS). Recent calls for more patient-friendly regimens have led to growing interest in the use of clomiphene citrate (CC) and aromatase inhibitors with or without gonadotropins to reduce the burden of hormonal injections. It is currently unknown whether regimens using CC or aromatase inhibitors such as letrozole (Ltz) are as effective as gonadotropins alone. OBJECTIVES To determine the effectiveness and safety of regimens including oral induction medication (such as clomiphene citrate or letrozole) versus gonadotropin-only regimens for controlled ovarian stimulation in IVF or intracytoplasmic sperm injection (ICSI) treatment. SEARCH METHODS We searched the following databases: Cochrane Gynaecology and Fertility Group Specialised Register (searched January 2017), the Cochrane Central Register of Controlled Trials (CENTRAL CRSO), MEDLINE (1946 to January 2017), Embase (1980 to January 2017), and reference lists of relevant articles. We also searched trials registries ClinicalTrials.gov (clinicaltrials.gov/) and the World Health Organization International Clinical Trials Registry Platform (www.who.int/trialsearch/Default.aspx). We handsearched relevant conference proceedings. SELECTION CRITERIA We included randomized controlled trials (RCTs). The primary outcomes were live-birth rate (LBR) and OHSS. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trial eligibility and risk of bias. We calculated risk ratios (RR) and Peto odds ratio (OR) with 95% confidence intervals (CIs) for dichotomous outcomes and mean differences (MD) for continuous outcomes. We analyzed the general population of women undergoing IVF treatment and (as a separate analysis) women identified as poor responders. We assessed the overall quality of the evidence using the GRADE approach. MAIN RESULTS We included 27 studies in the updated review. Most of the new trials in the updated review included poor responders and evaluated Ltz protocols. We could perform meta-analysis with data from 22 studies including a total of 3599 participants. The quality of the evidence for different comparisons ranged from low to moderate. The main limitations in the quality of the evidence were risk of bias associated with poor reporting of study methods, and imprecision.In the general population of women undergoing IVF, it is unclear whether CC or Ltz used with or without gonadotropins compared to use of gonadotropins along with gonadotropin-releasing hormone (GnRH) agonists or antagonists resulted in a difference in live birth (RR 0.92, 95% CI 0.66 to 1.27, 4 RCTs, n = 493, I2 = 0%, low-quality evidence) or clinical pregnancy rate (RR 1.00, 95% CI 0.86 to 1.16, 12 RCTs, n = 1998, I2 = 3%, moderate-quality evidence). This means that for a typical clinic with 23% LBR using a GnRH agonist regimen, switching to CC or Ltz protocols would be expected to result in LBRs between 15% and 30%. Clomiphene citrate or Ltz protocols were associated with a reduction in the incidence of OHSS (Peto OR 0.21, 95% CI 0.11 to 0.41, 5 RCTs, n = 1067, I2 = 0%, low-quality evidence). This means that for a typical clinic with 6% prevalence of OHSS associated with a GnRH regimen, switching to CC or Ltz protocols would be expected to reduce the incidence to between 0.5% and 2.5%. We found evidence of an increase in cycle cancellation rate with the CC protocol compared to gonadotropins in GnRH protocols (RR 1.87, 95% CI 1.43 to 2.45, 9 RCTs, n = 1784, I2 = 61%, low-quality evidence). There was moderate quality evidence of a decrease in the mean number of ampoules used,) and mean number of oocytes collected with CC with or without gonadotropins compared to the gonadotropins in GnRH agonist protocols, though data were too heterogeneous to pool.Similarly, in the poor-responder population, it is unclear whether there was any difference in rates of live birth (RR 1.16, 95% CI 0.49 to 2.79, 2 RCTs, n = 357, I2 = 38%, low-quality evidence) or clinical pregnancy (RR 0.85, 95% CI 0.64 to 1.12, 8 RCTs, n = 1462, I2 = 0%, low-quality evidence) following CC or Ltz with or without gonadotropin versus gonadotropin and GnRH protocol. This means that for a typical clinic with a 5% LBR in the poor responders using a GnRH protocol, switching to CC or Ltz protocols would be expected to yield LBRs between 2% to 14%. There was low quality evidence that the CC or Ltz protocols were associated with an increase in the cycle cancellation rate (RR 1.46, 95% CI 1.18 to 1.81, 10 RCTs, n = 1601, I2 = 64%) and moderate quality evidence of a decrease in the mean number of gonadotropin ampoules used and the mean number of oocytes collected, though data were too heterogeneous to pool. The adverse effects of these protocols were poorly reported. In addition, data on foetal abnormalities following use of CC or Ltz protocols are lacking. AUTHORS' CONCLUSIONS We found no conclusive evidence indicating that clomiphene citrate or letrozole with or without gonadotropins differed from gonadotropins in GnRH agonist or antagonist protocols with respect to their effects on live-birth or pregnancy rates, either in the general population of women undergoing IVF treatment or in women who were poor responders. Use of clomiphene or letrozole led to a reduction in the amount of gonadotropins required and the incidence of OHSS. However, use of clomiphene citrate or letrozole may be associated with a significant increase in the incidence of cycle cancellations, as well as reductions in the mean number of oocytes retrieved in both the general IVF population and the poor responders. Larger, high-quality randomized trials are needed to reach a firm conclusion before they are adopted into routine clinical practice.

Abstract
OBJECTIVE our meta-analysis was conducted to evaluate the effectiveness of the mild ovulation induction protocol using CC/gonadotropin/GnRH antagonist compared to the conventional GnRH agonist protocol in women undergoing ART. METHOD Six electronic databases were searched from their date of establishment until August 2016. Outcomes in our analysis were calculated in terms of relative risk (RR) and weighted mean differences (WMD) and standard mean differences (SMD) with 95% confidence intervals (CI) using random effect models or fixed effect models. RESULTS Six prospective controlled clinical trials with 1543 women comparing the clinical impacts of the two protocols were included. The synthesized results suggested a significant reduction in the quantity of gonadotropins (SMD: -1.96, 95% CI: -2.28 to 1.64, I2 = 78.5%), the incidence of OHSS (RR: 0.16, 95% CI 0.03-0.86, I2 = 0%) and an increase in the cycle cancelation rate (RR: 1.46, 95% CI 1.05-2.03, I2 = 89.4%). While no evidence of statistically significant differences between the groups existed in the other clinical outcomes. CONCLUSION This study suggested that the probable benefits of the mild protocol, including its less costs and safer process without reducing the overall IVF treatment success rates, seemed to make it a better treatment option. Larger sample prospective trials evaluating live birth, clinical pregnancy, OHSS, multiple pregnancy incidence and so on were desired to establish.

Abstract
OBJECTIVES To study the role of ovarian stimulation procedures on the risk of pregnancy-induced hypertension, gestational diabetes mellitus and neonatal outcomes according to women's characteristics and the causes of infertility. DESIGN Retrospective, observational, case/control study. PATIENTS Spontaneous pregnancies (group A, n=8107), pregnancies achieved after mild ovarian ovulation induction without other Assisted Reproductive Technology (ART) procedures (group B, n=44), pregnancies after mild ovarian stimulation and ART procedures (group C, n=53) or pregnancies after multi (>2) follicular stimulation with gonadotrophin therapy and ART procedures (group D, n=133); all of the groups had identical protocols for prenatal care. MAIN OUTCOME MEASUREMENTS Pregnancy-induced hypertension (PIH), fetal macrosomia (estimated fetal weight >90th percentile), gestational diabetes mellitus, caesarean section, and neonatal outcomes. RESULTS The incidence rates of PIH (2.7, 11.6, 4.2, and 2.5%) in groups A, B, C and D, respectively, (p=0.004), fetal macrosomia (4.7, 7.0, 20.8, and 7.6%, respectively, p<0.001), caesarean section (21.8, 37.2, 21.7, and 17.6%, respectively, p=0.048), differed among the groups. The high incidence of PIH in pregnancies following ovulation induction was driven by polycystic ovarian syndrome (PCOS) per se. CONCLUSION PCOS per se was associated with more PIH, and ART procedures after mild mono/bi follicular ovarian stimulation were associated with more fetal macrosomia.

Abstract
Mild controlled ovarian hyperstimulation (COH) protocols combining clomiphene citrate (CC) or letrozole with gonadotropins were introduced as an effective alternative of conventional COH in normal responders undergoing IVF/ICSI. In this case-control study, we compared 41 participants treated with a mild stimulation protocol receiving gonadotropins combined with either CC (n = 24) or letrozole (n = 17) with 71 subfertile participants with matching baseline characteristics, conforming with the same inclusion criteria and treated with a conventional antagonist protocol. Live birth was determined in reduced rates in the study group compared to the control group, reaching marginal statistical significance [4/41 versus 19/71, p = 0.050], as also in the respective number of clinical pregnancies [6/41 versus 22/71, p = 0.054], although the incidence of miscarriage was similar for both groups [2/41 versus 5/71, p = 0.714]. Most of the secondary parameters examined, favored the conventional antagonist protocol. There was no difference in any of the outcomes reported between the three different stimulation groups in post-hoc analysis. Mild stimulation regimens with the aid of either CC or letrozole employing GnRH antagonists do not seem to constitute an equally effective method as compared to the conventional antagonist protocol to be offered in good prognosis subfertile women seeking an induced cycle toward IVF/ICSI.

Abstract
So-called mild controlled ovarian hyperstimulation (mCOH) has in recent years increased in popularity, claiming to be safer and more patient-friendly, while also improving in vitro fertilization (IVF) outcomes. We here challenge the International Society for Mild Approaches in Assisted Reproduction (ISMAAR) definition of mild stimulation, and especially address four fundamental issues, where our review found conventional COH (cCOH) advantageous over mCOH. They are: prevalence of severe ovarian hyperstimulation syndrome (OHSS), oocyte/embryo quality, pregnancy/live birth rates, and cost. We conclude that an objective review of the literature does not support the routine utilization of mCOH in assisted reproduction.

Abstract
The objective of this study was to investigate the effects of low-dose hCG supplementation on ICSI outcomes and controlled ovarian stimulation (COS) cost. Three hundred and thirty patients undergoing ICSI were split into groups according to the COS protocol: (i) control group (n = 178), including patients undergoing conventional COS treatment; and (ii) low-dose hCG group (n = 152), including patients undergoing COS with low-dose hCG supplementation. Lower mean total doses of FSH administered and higher mean oestradiol level and mature oocyte rates were observed in the low-dose hCG group. A significantly higher fertilization rate, high-quality embryo rate and blastocyst formation rate were observed in the low-dose hCG group as compared to the control group. The miscarriage rate was significantly higher in the control group compared to the low-dose hCG group. A significantly lower incidence of OHSS was observed in the low-dose hCG group. There was also a significantly lower gonadotropin cost in the low-dose hCG group as compared to the control group ($1235.0 ± 239.0×$1763.0 ± 405.3, p < 0.001). The concomitant use of low-dose hCG and FSH results in a lower abortion rate and increased number of mature oocytes retrieved, as well as improved oocyte quality, embryo quality and blastocyst formation and reduced FSH requirements.

Ovarian stimulation protocols for IVF: is more better than less? Reprod Biomed Online 2017; 34:345-353.

Abstract
Conventional ovarian stimulation protocols for IVF are designed to achieve maximum oocyte yields. Conventional protocols, however, are associated with patient discomfort, increased risk of ovarian hyperstimulation syndrome and higher costs. In recent years, mild stimulation protocols have risen in popularity. These protocols typically use lower doses (≤150 IU/day), shorter duration of exogenous gonadotrophins, or both, compared with conventional protocols, with the goal of limiting the number of retrieved oocytes to less than eight. The pregnancy rate per cycle (fresh embryo transfer only) is lower with mild stimulation compared with conventional stimulation; however, the cumulative pregnancy rate seems to be comparable between the approaches. Reports are conflicting on the effects of mild versus conventional stimulation on embryo quality. This article expands on a live debate held at the American Society for Reproductive Medicine 2015 Annual Meeting to compare the advantages and disadvantages of the 'more is better' (conventional protocol) versus 'less is best' (mild protocol) approaches to ovarian stimulation. Both protocols are associated with benefits and challenges, and physicians must consider the needs of the individual patient when determining the best treatment options. Further prospective studies comparing a variety of outcomes with conventional and mild stimulation are needed.

Abstract
This work examined the trend in "embryo wastage" rates after ART in USA and its relationship to the number of embryos transferred, live born infants delivered across patient age, and the yearly percentage of embryos wasted. The data were obtained from the US-clinics SART databank for the years 2004-2013. A total of 1,808,082 non-donor embryos were transferred in 748,394 fresh cycles resulting in 358,214 liveborn. During the years of analysis, the mean number of embryos transferred has progressively decreased leading to an overall significant decrease in Embryo Wastage rates (83.2 to 76.5%, p < 0.001) while the percentage of transfers leading to a live born increased (24.8 to 27.8%, p = 0.002). Embryo Wastage negatively correlated with percentage of transfers resulting in live birth (p = 0.001), and the average number of embryos transferred positively correlated with the percentage of embryos wasted (p < 0.001). The overwhelming majority of embryos transferred still do not result into a live birth confirming that only few embryos per ART cycle are competent. The overall "Embryo Wastage" rates have consistently decreased from a high of 90% in 1995 to a rate of 76.5% in 2013. Transferring fewer embryos particularly at the blastocyst-stage and improved methods of embryo selection may further decrease "Embryo Wastage" rates.

Abstract
AIM As no upper limit of the daily dose of gonadotropins (DD GN) used for controlled ovarian hyperstimulation (COH) in patients undergoing assisted reproductive technology (ART) has been established, we aimed to evaluate the efficacy of using different DD GN in terms of live-birth achievement. METHODS Data of patients treated at a single university medical center during the same period was analyzed retrospectively. Four groups were analyzed according to the DD GN administered: group I ("high dose"): >225- ≤ 375 IU; Group II ("Very high dose"): 376-450 IU; group III ("extremely high dose"): 451-600 IU. Normo-responders treated with DD GN ≤250 IU served as control (C). Variables included were DD GN, total GN dose/cycle, age, FSH, BMI, gravidity, parity, cycle number, IVF/ICSI, infertility diagnosis treatment protocol and outcome parameters. RESULTS The analysis of 1394 treatment cycles of 943 patients indicated that DD and total dose of GN correlated negatively with the number of oocytes, implantation, clinical pregnancy and live-birth rate (25.9%, 14.6%, 11.4% and 4.7% in groups C, I, II and III, respectively) The logistic regression analysis indicated that the adjusted odds ratios for LBR correlated inversely with the DD administered - independently from age, baseline FSH, BMI and previous failed cycles. CONCLUSIONS Increasing the daily dose of GN to doses higher than 450 IU or a total dose of 3000 IU/cycle is at least questionable if not harmful.

Abstract
OBJECTIVE Corifollitropin alfa is a good choice for assisted reproductive technology (ART) cycles because fewer injections are needed than with other agents. In this retrospective cohort, we analyzed luteal injected half-dose depot gonadotropin hormone-releasing hormone (GnRH) agonist cycles in women who received corifollitropin alfa and those who underwent a conventional corifollitropin alfa cycle with a GnRH antagonist. MATERIAL AND METHODS In this retrospective cohort, we analyzed luteal injected half-dose depot GnRH agonist cycles in women who received corifollitropin alfa and those who underwent a conventional corifollitropin alfa cycle with a GnRH antagonist at the Division of Reproductive Endocrinology and IVF Unit, Obstetrics and Gynecology Department, Başkent University School of Medicine, Adana, Turkey, from March 2014 to August 2015. The patient's baseline characteristics were similar between the two groups. Forty-five patients underwent the long protocol, in which a half-dose of depot GnRH agonist was administered on day 21 of the preceding cycle. Forty-nine patients underwent the GnRH-antagonist protocol. Corifollitropin alfa was administered on the menstrual cycle day 3. RESULTS The mean ages of the two groups were similar (32.77±5.55 vs. 34.2±4.51 years ["for the long- and antagonist-protocol groups, respectively"]). The total number of retrieved oocytes, the fertilization rate, and the number of transferred embryos were similar between the two groups. The only significant difference between the two protocols was the number of injections during the controlled ovarian stimulation (COH) cycle, which included the depot-agonist injection in the long-protocol group (4.46±1.64 vs. 5.71±2.51, p=0.006). The clinical pregnancy and implantation rates were similar in the two protocols (16/45 [35.6%] vs. 16/49 [32.7%] for the intention to treat and 32.5±6.82% vs. 36.25±8.58%, respectively). CONCLUSION Our results show that ART cycles could be performed with fewer injections using corifollitropin alfa and a half-dose of depot GnRH agonist.

Abstract
Quality of life of young cancer survivors has become a major issue. However, anticancer therapies can have a detrimental impact on fertility. It is now well-established that all patients should receive information about the fertility risks associated with their cancer treatment and the fertility preservation options available. Currently, oocyte or embryo banking after controlled ovarian hyperstimulation represents the most effective method for preserving female fertility. Over the past years innovative protocols of ovarian stimulation have been developed to enable cancer patients to undergo oocyte or embryo cryopreservation irrespective of the phase of the cycle or without exogenous follicle-stimulating hormone-related increase in serum estradiol levels. The present article reviews the different protocols of ovarian hyperstimulation for cancer patients, candidates for fertility preservation.

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
STUDY HYPOTHESIS Maternal ageing and ovarian stimulation result in the accumulation of mitochondrial DNA (mtDNA) deletions and heteroplasmy in individual oocytes from a novel bovine model for human assisted reproductive technology (ART). STUDY FINDING The levels of mtDNA deletions detected in oocytes increased with ovarian ageing. Low levels of mtDNA heteroplasmy were apparent across oocytes and no relationship was identified with respect to ovarian ageing or ovarian stimulation. WHAT IS KNOWN ALREADY Oocyte quality decreases with ovarian ageing and it is postulated that the mtDNA may have a role in this decline. The impact of ovarian stimulation on oocyte quality is poorly understood. Human studies investigating these effects are often limited by the use of low quality oocytes and embryos, variation in age and ovarian stimulation regimens within the patients studied, as well as genetic and environmental variability. Further, no study has investigated mtDNA heteroplasmy in individual oocytes using next-generation sequencing (NGS), and little is known about whether the oocyte accumulates heteroplasmic mtDNA mutations following ageing or ovarian stimulation. STUDY DESIGN, SAMPLES/MATERIALS, METHODS A novel bovine model for the effect of stimulation and age in human ART was undertaken using cows generated by somatic cell nuclear transfer (SCNT) from one founder, to produce a homogeneous population with reduced genetic and environmental variability. Oocytes and somatic tissues were collected from young (3 years of age; n = 4 females) and old (10 years of age; n = 5 females) cow clones following multiple natural ovarian cycles, as well as oocytes following multiple mild (FSH only) and standard (based on human a long GnRH agonist protocol) ovarian stimulation cycles. In addition, oocytes were recovered in a natural cycle from naturally conceived cows aged 4-13.5 years (n = 10) to provide a heterogeneous cohort for mtDNA deletion studies. The presence or absence of mtDNA deletions were investigated using long-range PCR in individual oocytes (n = 62). To determine the detection threshold for mtDNA heteroplasmy levels in individual oocytes, a novel NGS methodology was validated; artificial mixtures of the Bos taurus and Bos indicus mitochondrial genome were generated at 1, 2, 5, 15 and 50% ratios to experimentally mimic different levels of heteroplasmy. This NGS methodology was then employed to determine mtDNA heteroplasmy levels in single oocytes (n = 24). Oocyte mtDNA deletion and heteroplasmy data were analysed by binary logistic regression with respect to the effects of ovarian ageing and ovarian stimulation regimens. MAIN RESULTS AND THE ROLE OF CHANCE Ovarian ageing, but not ovarian stimulation, increased the number of oocytes exhibiting mtDNA deletions (P = 0.04). A minimum mtDNA heteroplasmy level of 2% was validated as a sensitive (97-100%) threshold for variant detection in individual oocytes using NGS. Few mtDNA heteroplasmies were detected across the individual oocytes, with only 15 oocyte-specific variants confined to two of the 24 oocytes studied. There was no relationship (P > 0.05) evident between ovarian ageing or ovarian stimulation and the presence of mtDNA heteroplasmies. LIMITATIONS, REASON FOR CAUTION The low number of oocytes collected from the natural ovarian cycles limited the analysis. Fertilization and developmental potential of the oocytes was not assessed as the oocytes were destroyed for mtDNA deletion and heteroplasmy analysis. WIDER IMPLICATIONS OF THE FINDINGS If the findings of this model apply to the human, this study suggests that the incidence of mtDNA deletions increases with age, but not with degree of ovarian stimulation, while the frequency of mtDNA heteroplasmies may be low regardless of ovarian ageing or level of ovarian stimulation. STUDY FUNDING AND COMPETING INTERESTS Funding was provided by Fertility Associates, the Nurture Foundation for Reproductive Research, the Fertility Society of Australia, and the Auckland Medical Research Foundation. J.C.P. is a shareholder of Fertility Associates and M.P.G. received a fellowship from Fertility Associates. The other authors of this manuscript declare no conflict of interest that could be perceived as prejudicing the impartiality of the reported research.

Abstract
Luteal phase deficiency (LPD) is described as a condition of insufficient progesterone exposure to maintain a regular secretory endometrium and allow for normal embryo implantation and growth. Recently, scientific focus is turning to understand the physiology of implantation, in particular the several molecular markers of endometrial competence, through the recent transcriptomic approaches and microarray technology. In spite of the wide availability of clinical and instrumental methods for assessing endometrial competence, reproducible and reliable diagnostic tests for LPD are currently lacking, so no type-IA evidence has been proposed by the main scientific societies for assessing endometrial competence in infertile couples. Nevertheless, LPD is a very common condition that may occur during a series of clinical conditions, and during controlled ovarian stimulation (COS) and hyperstimulation (COH) programs. In many cases, the correct approach to treat LPD is the identification and correction of any underlying condition while, in case of no underlying dysfunction, the treatment becomes empiric. To date, no direct data is available regarding the efficacy of luteal phase support for improving fertility in spontaneous cycles or in non-gonadotropin induced ovulatory cycles. On the contrary, in gonadotropin in vitro fertilization (IVF) and non-IVF cycles, LPD is always present and progesterone exerts a significant positive effect on reproductive outcomes. The scientific debate still remains open regarding progesterone administration protocols, specially on routes of administration, dose and timing and the potential association with other drugs, and further research is still needed.

Why more is less and less is more when it comes to ovarian stimulation. J Assist Reprod Genet 2015; 32:1713-9. [PMID: 26481501 DOI: 10.1007/s10815-015-0599-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2015] [Accepted: 10/08/2015] [Indexed: 12/21/2022] Open
Abstract
PURPOSE The purpose of the present study is to describe the possible mechanisms which may explain the apparent paradox of "less is more." Mild ovarian stimulation for in vitro fertilization (IVF) minimizes ovarian hyperstimulation syndrome (OHSS) and multiple gestations without compromising the pregnancy rate (PR). METHODS The pertinent English literature (PubMed) addressing mild stimulation for IVF/assisted reproductive technology (ART) and publications addressing "mild" or "soft" controlled ovarian stimulation (COS) vs conventional COS for IVF, OHSS, natural cycle IVF, and IVF outcome in association with COS was searched. RESULTS Four possible mechanisms can be put forward to explain the apparent paradox of "less is more." (1) In the natural or mild stimulation cycles, the healthiest follicles are selected by the principle of "quality for quantity"; (2) high estradiol (E2) in the late follicular phase significantly correlated with higher rates of small for gestational age (SGA) and low-birth-weight (LBW) neonates; (3) anti-Mullerian hormone (AMH), LH, testosterone, and E(2) are significantly higher in natural cycle (NC)-IVF than in stimulated IVF follicles, suggesting an alteration of the follicular metabolism in stimulated cycles; and (4) supraphysiological E(2) may increase the growth hormone-binding protein (GH-BP) bio-neutralizing GH and diminishing the resultant insulin-like growth factor (IGF) levels, necessary for optimal synergism with follicle-stimulating hormone (FSH). CONCLUSIONS It is suggested to aim at the retrieval of around eight to ten eggs. Mild stimulation should be the common practice for IVF. In cases where more than ten ova are retrieved or high E(2) levels are reached, either intentionally or unintentionally, "freeze-all policy" should be considered and embryo transfer (ET) done in a subsequent natural cycle.

Abstract
OBJECTIVE To evaluate the correlation between total gonadotropin dose and live birth rate. DESIGN Retrospective analysis. SETTING Not applicable. PATIENT(S) A total of 658,519 fresh autologous cycles of in vitro fertilization (IVF) reported to the Society for Assisted Reproductive Technology from 2004 to 2012. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Logistic regression models were fitted to live birth rates with the use of categorized values for total FSH dose and number of oocytes retrieved as the primary predictor variables. To reduce the effect of the most significant confounders that may lead physicians to prescribe higher doses of FSH, additional analyses were performed limited to good-prognosis patients (<35 years of age, body mass index <30 kg/m(2), and no diagnosis of diminished ovarian reserve, endometriosis, or ovulatory disorder) and including duration of gonadotropin treatment. RESULT(S) Live birth rate significantly decreased with increasing FSH dose, regardless of the number of oocytes retrieved. The statistically significant decrease in live birth rate with increasing FSH dose remained in patients with good prognosis, and regardless of female age, except for women aged ≥ 35 years with 1-5 oocytes retrieved. CONCLUSION(S) This analysis suggests that physicians may wish to avoid prescribing a high dose of FSH. However, the results of this study do not justify the use of minimal-stimulation or natural-cycle IVF.

Abstract
STUDY QUESTION Does maternal ageing and ovarian stimulation alter mitochondrial DNA (mtDNA) copy number and gene expression of oocytes and cumulus cells from a novel bovine model for human IVF? SUMMARY ANSWER Oocytes collected from females with identical nuclear genetics show decreased mtDNA copy number and increased expression of an endoplasmic reticulum (ER) stress gene with repect to ovarian stimulation, whilst differences in the expression of genes involved in mitochondrial function, antioxidant protection and apoptosis were evident in relation to maternal ageing and the degree of ovarian stimulation in cumulus cells. WHAT IS KNOWN ALREADY Oocyte quality declines with advancing maternal age; however, the underlying mechanism, as well as the effects of ovarian stimulation are poorly understood. Human studies investigating these effects are often limited by differences in age and ovarian stimulation regimens within a patient cohort, as well as genetic and environmental variability. STUDY DESIGN, SIZE, DURATION A novel bovine cross-sectional maternal age model for human IVF was undertaken. Follicles were aspirated from young (3 years of age; n = 7 females) and old (10 years of age; n = 5 females) Holstein Freisian clones following multiple unstimulated, mild and standard ovarian stimulation cycles. These bovine cloned females were generated by the process of somatic cell nuclear transfer (SCNT) from the same founder and represent a homogeneous population with reduced genetic and environmental variability. Maternal age and ovarian stimulation effects were investigated in relation to mtDNA copy number, and the expression of 19 genes involved in mitochondrial function, antioxidant protection, oocyte-cumulus cell signalling and follicle development in both oocytes and cumulus cells. MATERIALS, SETTING, METHODS Young (3 years of age; n = 7 females) and old (10 years of age; n = 5 females) Holstein Freisian bovine clones were maintained as one herd. Stimulation cycles were based on the long GnRH agonist down-regulation regimen used in human fertility clinics. Follicle growth rates, numbers and diameters were monitored by ultrasonography and aspirated when the lead follicles were >14 mm in diameter. Follicle characteristics were analysed using a mixed model procedure. Quantitative PCR (qPCR) was used to determine mtDNA copy number and reverse transcriptase-qPCR (RT-qPCR) was used to measure gene expression in oocytes and cumulus cells. MAIN RESULTS AND THE ROLE OF CHANCE Method of ovarian stimulation (P = 0.04), but not maternal age (P > 0.1), was associated with a lower mtDNA copy number in oocytes. Neither factor affected mtDNA copy number in cumulus cells. In oocytes, maternal age had no effect on gene expression; however, ovarian stimulation in older females increased the expression of GRP78 (P = 0.02), a gene involved in ER stress. In cumulus cells, increasing maternal age was associated with the higher expression of genes involved in mitochondrial maintenance (TXN2 P = 0.008 and TFAM P = 0.03), whereas ovarian stimulation decreased the expression of genes involved in mitochondrial oxidative stress and apoptosis (TXN2 P = 0.002, PRDX3 P = 0.03 and BAX P = 0.03). LIMITATIONS, REASON FOR CAUTION The low number of oocyte and cumulus cell samples collected from the unstimulated cycles limited the analysis. Fertilization and developmental potential of the oocytes was not assessed because these were used for mtDNA and gene expression quantification. WIDER IMPLICATIONS OF THE FINDINGS Delineation of the independent effects of maternal age and ovarian stimulation regimen on mtDNA copy number gene expression in oocytes and cumulus cells was enabled by the removal of genetic and environmental variability in this bovine model for human IVF. Therefore, these extend upon previous knowledge and findings provide relevant insights that are applicable for improving human ovarian stimulation regimens.

Abstract
OBJECTIVE To investigate efficacy and safety of a controlled ovarian stimulation (COS) protocol in which a single dose of Corifollitropin-alfa (CFα) was administered on day 4 of a GnRH-antagonist cycle. DESIGN Cohort case-control study. SETTING University Hospital. PATIENTS One hundred twenty-two normally cycling women expected to be normal responders to COS. INTERVENTIONS In 61 patients, CFα (100-150 μg) was injected subcutaneously on day 4 of a spontaneous menstrual cycle; a GnRH-antagonist was added from day 8 (fixed protocol; 0.25 mg/day). If needed to complete follicular maturation, recombinant FSH (rFSH) daily injections (150/200 IU/day) were given from day 11. A control group of 61 matched women was stimulated with daily subcutaneous injections of rFSH (100-150 U/day) from day 4 of the cycle, and received GnRH-antagonist (0.25 mg/day) from day 8. IVF or ICSI was performed according to the sperm characteristics, and 1-2 embryos were transferred in utero under US guidance on day 2. MAIN OUTCOME MEASURES Number of retrieved cumulus-oocyte complexes (COCs), clinical pregnancy rate (PR), implantation rate (IR), ongoing PR at 10 weeks, number of injections/cycle, ovarian hyperstimulation syndrome (OHSS) rate. RESULTS No cycle was cancelled and the mean number of retrieved COCs was comparable in patients and controls. About 60% of CF-alfa treated women had no need of daily rFSH addition, and the mean number of injections/cycle was significantly lower in the CF-alfa group than in controls (p < 0.05). The ongoing PR/transfer was 36.8% in CF-alfa group and 37.5% in controls. No patient developed severe OHSS, and the incidence of moderate OHSS was similar in cases and controls. CONCLUSIONS CFα may be started on day 4 of the cycle obtaining results comparable to those of a COS using day 4-start daily rFSH, with significantly less injections and a similar risk of OHSS.

Abstract
OBJECTIVES To compare the effectiveness of in vitro fertilisation with single embryo transfer or in vitro fertilisation in a modified natural cycle with that of intrauterine insemination with controlled ovarian hyperstimulation in terms of a healthy child. DESIGN Multicentre, open label, three arm, parallel group, randomised controlled non-inferiority trial. SETTING 17 centres in the Netherlands. PARTICIPANTS Couples seeking fertility treatment after at least 12 months of unprotected intercourse, with the female partner aged between 18 and 38 years, an unfavourable prognosis for natural conception, and a diagnosis of unexplained or mild male subfertility. INTERVENTIONS Three cycles of in vitro fertilisation with single embryo transfer (plus subsequent cryocycles), six cycles of in vitro fertilisation in a modified natural cycle, or six cycles of intrauterine insemination with ovarian hyperstimulation within 12 months after randomisation. MAIN OUTCOME MEASURES The primary outcome was birth of a healthy child resulting from a singleton pregnancy conceived within 12 months after randomisation. Secondary outcomes were live birth, clinical pregnancy, ongoing pregnancy, multiple pregnancy, time to pregnancy, complications of pregnancy, and neonatal morbidity and mortality RESULTS 602 couples were randomly assigned between January 2009 and February 2012; 201 were allocated to in vitro fertilisation with single embryo transfer, 194 to in vitro fertilisation in a modified natural cycle, and 207 to intrauterine insemination with controlled ovarian hyperstimulation. Birth of a healthy child occurred in 104 (52%) couples in the in vitro fertilisation with single embryo transfer group, 83 (43%) in the in vitro fertilisation in a modified natural cycle group, and 97 (47%) in the intrauterine insemination with controlled ovarian hyperstimulation group. This corresponds to a risk, relative to intrauterine insemination with ovarian hyperstimulation, of 1.10 (95% confidence interval 0.91 to 1.34) for in vitro fertilisation with single embryo transfer and 0.91 (0.73 to 1.14) for in vitro fertilisation in a modified natural cycle. These 95% confidence intervals do not extend below the predefined threshold of 0.69 for inferiority. Multiple pregnancy rates per ongoing pregnancy were 6% (7/121) after in vitro fertilisation with single embryo transfer, 5% (5/102) after in vitro fertilisation in a modified natural cycle, and 7% (8/119) after intrauterine insemination with ovarian hyperstimulation (one sided P=0.52 for in vitro fertilisation with single embryo transfer compared with intrauterine insemination with ovarian hyperstimulation; one sided P=0.33 for in vitro fertilisation in a modified natural cycle compared with intrauterine insemination with controlled ovarian hyperstimulation). CONCLUSIONS In vitro fertilisation with single embryo transfer and in vitro fertilisation in a modified natural cycle were non-inferior to intrauterine insemination with controlled ovarian hyperstimulation in terms of the birth of a healthy child and showed comparable, low multiple pregnancy rates.Trial registration Current Controlled Trials ISRCTN52843371; Nederlands Trial Register NTR939.

Abstract
In contrast to current approaches, the aim of mild stimulation is to develop safer and more patient-friendly protocols in which the risks of the treatment as a whole are minimized. Mild stimulation is defined as the method when exogenous gonadotropins are administered at lower doses, and/or for a shorter duration in GnRH antagonist co-treated cycles, or when oral compounds (antiestrogens, aromatase inhibitors) are used for ovarian stimulation for IVF, with the aim of limiting the number of oocytes obtained to fewer than eight. In this chapter we discuss the relevant physiology of follicle development, the development of milder stimulation protocols, the implications of mild stimulation, the current state of affairs, and future developments.

Abstract
Despite the development of in vitro fertilization (IVF) more than 30 years ago, the cost of treatment remains high. Furthermore, over the years, more sophisticated technologies and expensive medications have been introduced, making IVF increasingly inaccessible despite the increasing need. Globally, the option to undergo IVF is only available to a privileged few. In recent years, there has been growing interest in exploring strategies to reduce the cost of IVF treatment, which would allow the service to be provided in low-resource settings. In this review, we explore the various ways in which the cost of this treatment can be reduced.

Abstract
STUDY QUESTION Does the initiation of corifollitropin alfa administration on cycle day 4 instead of cycle day 2 result in a reduced total rFSH consumption in a GnRH antagonist protocol? SUMMARY ANSWER Initiation of corifollitropin alfa on cycle day 4 compared with day 2 results in significantly reduced total rFSH consumption at the end of the follicular phase. WHAT IS KNOWN ALREADY In vitro fertilization treatment is associated with significant physical, psychological and emotional stress in infertile patients. This notion has fuelled the search for simplified treatment approaches that may reduce the treatment burden. The introduction of corifollitropin alfa has provided a more patient-friendly treatment protocol because it obviates the need for daily hormonal injections. In addition, postponing the initiation of hormonal stimulation should also reduce the total gonadotrophin consumption and the number of injections needed. STUDY DESIGN, SIZE, DURATION A prospective randomized controlled pilot study was conducted in a university centre in Belgium. Between December 2011 and March 2013, 59 patients were randomized in the study and 52 of these patients received the allocated intervention. PARTICIPANTS/MATERIALS, SETTING, METHODS All patients were randomly assigned to the control group (CD2), with initiation of corifollitropin alfa on cycle day 2, or to the study group (CD4) with initiation of stimulation on day 4. The GnRH antagonist was administered from cycle day 7 onwards in both treatment arms. The main outcome measure was the total rFSH consumption at the end of the follicular phase after corifollitropin alfa treatment. MAIN RESULTS AND THE ROLE OF CHANCE The total dose of rFSH at the end of the follicular phase was significantly reduced in the CD4 group compared with the CD2 group (324 (276) IU in the CD2 group versus 173 (255) IU in the CD4 group, P = 0.015, mean difference -151, 95% confidence interval (CI) -301 to -1). A significant reduction of total duration of rFSH stimulation in the CD4 group was also observed (8.6 (1.4) days in CD2 group versus 7.8 (1.2) days in the CD4 group, P = 0.008, mean difference -0.8, 95% CI -1.6 to -0.1). The number of cumulus-oocyte-complexes was comparable in both treatment groups (12.8 (7.3) in CD2 group versus 14.7 (8.8) in the CD4 group, P = 0.461, mean difference 1.8, 95% CI -2.7 to 6.4). Ongoing pregnancy rates of 48% in the CD2 group and 41% in the CD4 group were achieved (P = 0.60, relative risk (RR) 0.85, 95% CI 0.46-1.56). Final oocyte maturation was triggered with GnRH agonist instead of hCG in two patients in the CD2 group and in eight patients in the CD4 group, because of an increased risk of ovarian hyperstimulation syndrome (P = 0.078, RR 3.7 (95% CI 0.88-15.8). LIMITATIONS, REASONS FOR CAUTION Before general implementation can be advised, this trial should be validated in a much larger randomized trial. WIDER IMPLICATIONS OF THE FINDINGS If the approach of starting ovarian stimulation on Day 4 of the cycle could be implemented in a large population of infertile patients, it would result in a significant reduction of gonadotrophin consumption. STUDY FUNDING/COMPETING INTEREST(S) No external finance was involved in this study. C.B and N.P.P. have received fees from MSD. Otherwise the authors declare no conflict of interest regarding this study. TRIAL REGISTRATION NUMBER The trial was registered at clinicaltrials.gov (NCT01633580).
