Abstract
STUDY QUESTION Can pregnancy outcomes following fresh elective single embryo transfer (eSET) in gonadotropin-releasing hormone (GnRH) antagonist protocols increase using a gonadotropin (Gn) step-down approach with cessation of GnRH antagonist on the day of hCG administration (hCG day) in patients with normal ovarian response? SUMMARY ANSWER The modified GnRH antagonist protocol using the Gn step-down approach and cessation of GnRH antagonist on the hCG day is effective in improving live birth rates (LBRs) per fresh eSET cycle. WHAT IS KNOWN ALREADY Currently, there is no consensus on optimal GnRH antagonist regimens. Studies have shown that fresh GnRH antagonist cycles result in poorer pregnancy outcomes than the long GnRH agonist (GnRHa) protocol. Endometrial receptivity is a key factor that contributes to this phenomenon. STUDY DESIGN, SIZE, DURATION An open label randomized controlled trial (RCT) was performed between November 2021 and August 2022. There were 546 patients allocated to either the modified GnRH antagonist or the conventional antagonist protocol at a 1:1 ratio. PARTICIPANTS/MATERIALS, SETTING, METHODS Both IVF and ICSI cycles were included, and the sperm samples used were either fresh or frozen from the partner, or from frozen donor ejaculates. The primary outcome was the LBRs per fresh SET cycle. Secondary outcomes included rates of implantation, clinical and ongoing pregnancy, miscarriage, and ovarian hyperstimulation syndrome (OHSS), as well as clinical outcomes of ovarian stimulation. MAIN RESULTS AND THE ROLE OF CHANCE Baseline demographic features were not significantly different between the two ovarian stimulation groups. However, in the intention-to-treat (ITT) population, the LBRs in the modified antagonist group were significantly higher than in the conventional group (38.1% [104/273] vs. 27.5% [75/273], relative risk 1.39 [95% CI, 1.09-1.77], P = 0.008). Using a per-protocol (PP) analysis which included all the patients who received an embryo transfer, the LBRs in the modified antagonist group were also significantly higher than in the conventional group (48.6% [103/212] vs. 36.8% [74/201], relative risk 1.32 [95% CI, 1.05-1.66], P = 0.016). The modified antagonist group achieved significantly higher implantation rates, and clinical and ongoing pregnancy rates than the conventional group in both the ITT and PP analyses (P < 0.05). The two groups did not show significant differences between the number of oocytes retrieved or mature oocytes, two-pronuclear zygote (2PN) rates, the number of embryos obtained, blastocyst progression and good-quality embryo rates, early miscarriage rates, or OHSS incidence rates (P > 0.05). LIMITATIONS, REASONS FOR CAUTION A limitation of our study was that the subjects were not blinded to the treatment allocation in the RCT trial. Only women under 40 years of age who had a good prognosis were included in the analysis. Therefore, use of the modified antagonist protocol in older patients with a low ovarian reserve remains to be investigated. In addition, the sample size for Day 5 elective SET was small, so larger trials will be required to strengthen these findings. WIDER IMPLICATIONS OF THE FINDINGS The modified GnRH antagonist protocol using the Gn step-down approach and cessation of GnRH antagonist on hCG day improved the LBRs per fresh eSET cycle in normal responders.

Bosch E, Alamá P, Romero JL, Marí M, Labarta E, Pellicer A. Serum progesterone is lower in ovarian stimulation with highly purified HMG compared to recombinant FSH owing to a different regulation of follicular steroidogenesis: a randomized controlled trial. Hum Reprod 2024; 39:393-402. [PMID: 38037188 DOI: 10.1093/humrep/dead251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 10/30/2023] [Indexed: 12/02/2023] Open
Abstract
STUDY QUESTION Does ovarian stimulation with highly purified (hp)-HMG protect from elevated progesterone in the follicular phase compared to recombinant FSH (r-FSH) cycles through a different regulation of follicular steroidogenesis? SUMMARY ANSWER hp-HMG enhanced the Δ4 pathway from pregnenolone to androstenodione leading to lower serum progesterone at the end of the cycle, while r-FSH promoted the conversion of pregnenolone to progesterone causing higher follicular phase progesterone levels. WHAT IS KNOWN ALREADY Elevated progesterone in the follicular phase has been related to lower clinical outcome in fresh IVF cycles. Progesterone levels are positively correlated to ovarian response, and some studies have shown that when r-FSH alone is used for ovarian stimulation serum progesterone levels on the day of triggering are higher than when hp-HMG is given. Whether this is caused by a lower ovarian response in hp-HMG cycles or to a difference in follicular steroidogenesis in the two ovarian stimulation regimens has not been well characterized. STUDY DESIGN, SIZE, DURATION A randomized controlled trial including 112 oocyte donors undergoing ovarian stimulation with GnRH antagonists and 225 IU/day of r-FSH (n = 56) or hp-HMG (n = 56) was carried out in a university-affiliated private infertility clinic. Subjects were recruited between October 2016 and June 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS The women were aged 18-35 years with a regular menstrual cycle (25-35 days) and normal ovarian reserve (serum anti-Müllerian hormone (AMH) = 10-30 pMol/l) undergoing ovarian stimulation for oocyte donation. FSH, LH, estradiol (E2), estrone, progesterone, pregnenolone, 17-OH-progesterone, androstenodione, dehidroepiandrostenodione, and testosterone were determined on stimulation Days 1, 4, 6, and 8 and on day of triggering in serum and in follicular fluid. Samples were frozen at -20°C until assay. Total exposures across the follicular phase were compared by polynomic extrapolation. MAIN RESULTS AND THE ROLE OF CHANCE Subjects in both groups were comparable in terms of age, BMI, and AMH levels. Ovarian response was also similar: 17.5 ± 7.9 (mean ± SD) versus 16.5 ± 7.5 oocytes with r-FSH and hp-HMG, respectively (P = 0.49). Serum progesterone (ng/ml) on day of trigger was 0.46 ± 0.27 in the hp-HMG group versus 0.68 ± 0.50 in the r-FSH group (P = 0.010). Differences for progesterone were also significant on stimulation days 6 and 8. The pregnenolone: progesterone ratio was significantly increased in the r-FSH group from stimulation day 8 to the day of trigger (P = 0.019). Serum androstenodione (ng/ml) on day of trigger was 3.0 ± 1.4 in the hp-HMG group versus 2.4 ± 1.1 in the r-FSH group (P = 0.015). Differences in adrostenodione were also significant on stimulation Day 8. The pregnenolone:androstenodione ratio was significantly higher in the hp-HMG group (P = 0.012) on Days 6 and 8 and trigger. There were no other significant differences between groups. Follicular fluid E2, FSH, LH, dehidroepioandrostenodione, androstenodione, and testosterone were significantly higher in the hp-HMG than r-FSH group. No differences were observed for progesterone, estrone, 17-OH-progesterone, and pregnenolone in follicular fluid. LIMITATIONS, REASONS FOR CAUTION All women included in the study were young, not infertile, and had a normal BMI and a good ovarian reserve. The findings might be different in other patient subpopulations. Hormone analyses with immunoassays are subject to intra-assay variations that may influence the results. WIDER IMPLICATIONS OF THE FINDINGS Stimulation with hp-HMG may prevent progesterone elevation at the end of the follicular phase because of a different follicular steroidogenesis pathway, regardless of ovarian response. This should be considered, particularly in patients at risk of having high progesterone levels at the end of the follicular phase when a fresh embryo transfer is planned.

BMC Pregnancy Childbirth 2023; 23:612. [PMID: 37626299 PMCID: PMC10464310 DOI: 10.1186/s12884-023-05943-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2023] [Accepted: 08/22/2023] [Indexed: 08/27/2023] Open
Abstract
OBJECTIVE To determine whether a reduced dose of follicle-stimulating hormone (FSH) before human chorionic gonadotropin (hCG) trigger during ovarian stimulation can affect in vitro fertilization (IVF) outcomes. METHODS This study included 347 patients with a normal ovarian response who received a reduced dose of FSH before hCG trigger for 2-3 days (Group A) and 671 patients who did not receive a reduced dose (Group B) from a university-affiliated IVF center between January 2021 and December 2022. The primary endpoint was estrogen (E2) and progesterone (P) levels on the day of hCG trigger, fresh embryo transfer cycles, laboratory outcomes, and clinical outcomes between the two groups. RESULTS On the day of hCG trigger, Group A had significantly lower E2 and P levels than those in Group B (3454.95 ± 1708.14 pg/mL versus 3798.70 ± 1774.26 pg/mL, p = 0.003; and 1.23 ± 0.53 ng/mL versus 1.37 ± 0.59 ng/mL, p < 0.001, respectively). The proportion of patients with P levels ≥ 1.5 ng/mL was 22.48% in Group A compared to 34.58% in Group B (p < 0.001), while the proportion of patients with E2 ≥ 5000 pg/mL was 15.27% in Group A compared to 25.93% in Group B (p < 0.001). The fresh embryo-transfer cycle rate in Group A was higher than that in group B (54.47% and 32.64%, respectively; p < 0.001). Despite the reduction in FSH dosage, there were no significant differences between groups regarding the number of oocytes retrieved, total number of mature oocytes, normal fertilization rate, cleavage rate, Day 3 top-quality rate, implantation rate, pregnancy rate per cycle, and early pregnancy loss rate. CONCLUSION While a reduced dose of FSH prior to hCG trigger during ovarian stimulation did not significantly affect IVF outcomes, it was associated with lower E2 and P levels, resulting in fewer cycles with E2 ≥ 5000 pg/mL and P ≥ 1.5 ng/mL on the day of the hCG trigger.

Abstract
BACKGROUND Luteinizing hormone (LH) is critical in follicle growth and oocyte maturation. However, the value of recombinant LH (r-LH) supplementation to recombinant follicle stimulating hormone (r-FSH) during controlled ovarian stimulation in the gonadotrophin releasing hormone (GnRH) antagonist regimen is controversial. METHODS This multicenter retrospective cohort study recruited 899 GnRH antagonist cycles stimulated with r-LH and r-FSH in 3 reproductive centers and matched them to 2652 r-FSH stimulating cycles using propensity score matching (PSM) for potential confounders in a 1:3 ratio. The primary outcome was the cumulative live birth rate (CLBR) per complete cycle. RESULTS The baseline characteristics were comparable in the r-FSH/r-LH and r-FSH groups after PSM. The r-FSH/r-LH group achieved a higher CLBR than the r-FSH group (66.95% vs. 61.16%, p = 0.006). R-LH supplementation also resulted in a higher 2-pronuclear embryo rate, usable embryo rate, and live birth rate in both fresh embryo transfer cycles and frozen-thawed embryo transfer (FET) cycles. No significant differences were found in the rate of moderate and severe ovarian hyperstimulation syndrome (OHSS), or cycle cancellation rate in the prevention of OHSS. CONCLUSIONS R-LH supplementation to r-FSH in the GnRH antagonist protocol was significantly associated with a higher CLBR and live birth rate in fresh and FET cycles, and improved embryo quality without increasing the OHSS rate and cycle cancellation rate.

Abstract
BACKGROUND Studies have suggested that controlled ovarian hyperstimulation adversely affects endometrial receptivity due to advanced endometrial maturation. This adverse effect is mainly attributed to supraphysiological levels of both estrogen and progesterone identified in stimulated cycles. There is a paucity of published data investigating the very early luteal steroid profile following hCG trigger. AIM OF THE STUDY This prospective, observational study was undertaken to determine the increase in serum progesterone levels after human chorionic gonadotrophin (hCG) trigger in stimulated IVF/ICSI cycles. MATERIALS AND METHODS This proof-of-concept study included 11 patients requiring ovarian stimulation for IVF/ICSI and who planned to avail of pre-implantation genetic screening with embryo vitrification of their biopsied embryos at blastocyst stage. For each study participant, five additional blood samples were drawn at the following specific times in the stimulation cycle, on the morning (10.00-12.00) of the assigned day to induce final oocyte maturation with hCG trigger, immediately prior to administration of hCG for final oocyte maturation, 1 h, 2 h, and 36 h post hCG trigger. A prediction model, the Gompertz curve, was used to determine serum progesterone levels at intervals between the 2 h post hCG trigger sample and the day of oocyte retrieval. RESULTS Statistically significant increases in serum progesterone levels were identified following hCG administration as early as 1 h following trigger (P4 0.57 ng/ml, p < 0.05), 2 h following trigger (P4 0.88 ng/ml, p < 0.001) and on the day of oocyte retrieval (P4 9.68 ng/ml, p < 0.001). According to our prediction model, the Gompertz curve, the projected serum progesterone level at 4 h post trigger would have achieved a level of 1.45 ng/ml, 8 h post trigger of 3.04 ng/ml, and 12 h post trigger of 4.8 ng/ml. The very early and significant increases in serum progesterone following hCG trigger are clearly demonstrated in this study. CONCLUSION The endometrium is undoubtedly exposed to rapidly increasing serum progesterone levels post hCG trigger that would not be identified until much later in natural menstrual cycles. TRIAL REGISTRATION NUMBER This study is registered with clinicaltrials.gov under the identifier NCT04417569.

Abstract
RESEARCH QUESTION What is the impact of systemic FSH concentrations during ovarian stimulation for IVF/intracytoplasmic sperm injection on systemic progesterone concentrations in the late follicular phase? DESIGN Post-hoc analysis of a previously performed randomized controlled trial (RCT) performed between November 2017 and February 2020 in a tertiary IVF centre. The RCT included patients with infertility undergoing ovarian stimulation in a gonadotrophin-releasing hormone (GnRH) antagonist protocol. The GnRH antagonist was administered at 08:00 h and recombinant FSH at 20:00 h. Ultrasound and blood tests were performed 3-5 h after the GnRH antagonist. RESULTS The subgroup analysis comprised 105 patients. Systemic FSH concentrations increased from Day 2/3 until initiation of GnRH antagonist and remained constant until the day of trigger (DoT). The total group was split according to the median FSH DoT concentration (12.95 IU/l; Group A <12.95 IU/l; Group B ≥12.95 IU/l). Significant differences, with the higher concentrations in Group B, were found for: systemic FSH concentration on Day 2/3 (P = 0.04), total gonadotrophin dosage (P = 0.03), progesterone on DoT (P = 0.001) and progesterone per follicle (P = 0.004). In the total group, systemic DoT FSH concentration was statistically significantly positively correlated with the DoT progesterone concentration and the ratio of progesterone per follicle (ρ = 0.37 and 0.38, respectively, both P < 0.001). No significant correlations were seen between the systemic DoT FSH concentration and the number of retrieved oocytes. CONCLUSION While ovarian response seems to be independent from the systemic FSH concentrations on the DoT, high concentrations of circulatory FSH augment the production of progesterone.

Abstract
Abstract
Background
Luteinizing hormone (LH) has the main role in ovarian function in both natural and artificial cycles. A normal LH concentration during controlled ovarian hyperstimulation is positively correlated to the number and quality of retrieved oocytes and resulting embryos.
Main body of the abstract
In this study, we reviewed whether rLH administration, adjunct to the ovarian stimulation regimen, could improve clinical outcomes. The literature review showed that rLH supplementation improves assisted reproductive technology (ART) outcomes among women with hypogonadotropic hypogonadism, and hyporesponsive women to follicle-stimulating hormone monotherapy. Besides, rLH supplementation has advantages for poor responder women 36–39 years of age. Even though the data suggested no priority regarding the LH source for improving ART outcome, women with different LH polymorphisms who did not respond similarly to ovarian stimulation may benefit from adjuvant rLH therapy.
Conclusion
rLH usage for improving ART outcome should be scrutinized via well-designed studies considering the subgroups of infertile women who benefit the most from rLH adjuvant therapy, the type of ovarian stimulation protocol to which rLH would be added, and also the exact dosage, as well as the proper timing (during or prior to a cycle).

Abstract
OBJECTIVE To evaluate the value of using both HMG and recombinant FSH (r-FSH) in the GnRH antagonist protocol for women with high AMH. MATERIALS AND METHODS This retrospective, single-center cohort study was conducted from January 2013 to December 2018. Of 277 GnRH antagonist IVF/ICSI cycles in women with anti-Mullerian hormone (AMH) ≥5 μg/L, 170 cycles receiving the combination of r-FSH and HMG (77 with HMG added at the beginning of the GnRH antagonist cycle and 93 with HMG added after GnRH antagonist administration) and 107 cycles receiving r-FSH alone were analyzed. The dynamic hormone profiles and embryonic and clinical outcomes of the patients were evaluated. RESULTS We observed significantly lower serum LH levels in the r-FSH + HMG groups during ovarian stimulation. The serum estradiol and progesterone levels were lower in the r-FSH + HMG groups on the trigger day. Nevertheless, there were no significant differences with respect to the number of oocytes retrieved, maturation, fertilization, blastocyst formation rate or ovarian hyperstimulation syndrome (OHSS). The implantation and live birth rates were increased in the r-FSH + HMG groups compared with the r-FSH alone group, with no statistical significance. CONCLUSIONS HMG for LH supplementation in the GnRH antagonist protocol for patients with high AMH is not significantly superior to r-FSH alone in terms of ovarian response and pregnancy outcome. Nevertheless, HMG supplementation might be appropriate for women with an initially inadequate response to r-FSH or intracycle LH deficiency.

Progesterone levels on the human chorionic gonadotropin trigger day affect the pregnancy rates for embryos transferred at different stages of development in both general and selected IVF/ICSI populations. BMC Pregnancy Childbirth 2021; 21:363. [PMID: 33957886 PMCID: PMC8101180 DOI: 10.1186/s12884-021-03832-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Accepted: 04/26/2021] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Two meta-analyses have shown that pregnancy and birth rates are significantly higher after blastocyst transfer than after cleaved embryo transfer. Other studies have revealed that a serum progesterone level > 1.5 ng/ml on the trigger day is responsible for premature luteinization and is associated with a low pregnancy rate. The objectives of this retrospective study were to determine whether blastocyst transfer gave higher pregnancy rates than cleaved embryo transfer at day 3 in both the general and selected IVF/ICSI populations, and whether the serum progesterone level influenced the pregnancy rate. METHOD We studied IVF/ICSI cycles with GnRH antagonist - FSH/hMG protocols in a general population (n = 1210) and a selected "top cycle" population (n = 677), after blastocyst transfer on day 5 or cleaved embryo transfer on day 3. The selected couples had to meet the following criteria: female age < 35, first or second cycle, and one or two embryos transferred. We recorded predictive factors for pregnancy and calculated the progesterone to oocyte index (POI), the progesterone:estradiol ratio (P:E2 ratio), and the progesterone to follicle (> 14 mm) index (PFI). RESULTS In the general population, the clinical pregnancy rate was significantly higher after blastocyst transfer (33.3%) than after cleaved embryo transfer (25.3%; p < 0.01); the same was true for the birth rate (32.1 and 22.8%, respectively, p < 0.01). The differences between blastocyst and embryo transfer groups were not significant in the selected population (respectively 35.7% vs. 35.8% for the clinical pregnancy rate, and 33.9 and 34.9% for the birth rate). The serum progesterone levels on the eve of the trigger day and on the day itself were significantly lower in the pregnant women (p < 0.01). We found a serum progesterone threshold of 0.9 ng/ml, as also reported by other researchers. The POI and the PFI appear to have predictive value for cleaved embryos transfers. CONCLUSIONS Blastocyst transfers were associated with higher clinical pregnancy and birth rates than cleaved embryo transfers in a general population but not in a selected population. The serum progesterone levels on the eve of the trigger day and on the day itself predicted the likelihood of pregnancy.

Abstract
STUDY QUESTION What is the early luteal phase hormonal profile in patients undergoing ovarian stimulation for IVF/ICSI followed by hCG trigger and a freeze-all strategy without luteal phase support? SUMMARY ANSWER The peak concentration of progesterone occurred 4 days after oocyte pick-up (OPU + 4), with an average 35% fall from OPU + 4 to OPU + 6, and progesterone levels before and 12 h after hCG administration predicted levels during the early luteal phase. WHAT IS KNOWN ALREADY The luteal phase during IVF differs from that during normal cycles, particularly with respect to the serum progesterone level profile. This can cause asynchrony between the embryo and the endometrium, potentially resulting in implantation failure and poor reproductive outcomes. STUDY DESIGN, SIZE, DURATION This prospective study included 161 women with normal ovarian reserve receiving GnRH antagonist co-treatment during ovarian stimulation with FSH who were followed up to 6 days after OPU in a single IVF cycle. PARTICIPANTS/MATERIALS, SETTING, METHODS Women aged 18-42 years undergoing IVF with ovarian stimulation using FSH were included. Ovulation was triggered with recombinant hCG 250 μg. Hormone levels were determined from blood samples taken on the day of trigger, before hCG, at 12, 24 and 36 h after hCG and at 1, 2, 3, 4, 5 and 6 days after OPU. The primary endpoint was early luteal phase serum concentrations of progesterone, LH, estradiol and hCG. MAIN RESULTS AND THE ROLE OF CHANCE One outlier with a pre-hCG serum progesterone level of 11.42 ng/mL was excluded, so all analyses included 160 subjects. Progesterone levels began to increase 1 day after OPU, peaked 4 days after OPU (114 ng/mL), then declined from OPU + 5 onwards. Peak progesterone levels were at OPU + 4, OPU + 5 or OPU + 6 in 38.8, 29.4 and 13.8% of patients, respectively. Approximately two-thirds of patients had a fall in serum progesterone from OPU + 4 to OPU + 6. Pre-hCG progesterone levels correlated significantly with those at 24 h after hCG (r2 = 0.28; P < 0.001), which in turn correlated significantly with progesterone at OPU + 4 (r2 = 0.32; P < 0.001). LH peaked (4.4 IU/L) 12 h after hCG trigger, persisting for 24 h but was barely elevated compared with physiological levels. Serum estradiol peaked twice: at 24 h post-trigger and at OPU + 4. Highest hCG levels (130 mIU/mL) occurred at 24 h post-injection. The best correlations between the number of follicles ≥11 mm and serum progesterone level were seen at 24 and 36 h after hCG and OPU + 1. LIMITATIONS, REASONS FOR CAUTION The influence of different profiles of serum progesterone on reproductive outcomes could not be determined because a freeze-all strategy was used in all patients. In addition, data were not available to relate serum hormone level findings with endometrial histology or endometrial receptivity analysis to clearly identify the relationship between serum hormones and the window of implantation. WIDER IMPLICATIONS OF THE FINDINGS Detailed information about early luteal phase hormone levels could be used to optimize and individualize luteal phase support to improve reproductive outcomes.

Abstract
A rise in serum progesterone in the late follicular phase is a well described adverse effect of ovarian stimulation for IVF/ICSI. Previous data suggest, that enhanced gonadotropin stimulation causes progesterone elevation and the incidence of premature progesterone elevation can be reduced by declining gonadotropin dosages. This randomized controlled trial (RCT) aimed to achieve a significant reduction of the progesterone level on the day of final oocyte maturation by a daily reduction of 12.5 IU rec-FSH from a follicle size of 14 mm in a GnRH-antagonist protocol. A total of 127 patients had been recruited (Control group (CG): 62 patients; Study group (SG): 65 patients). Due to drop out, data from 108 patients (CG: 55 patients; SG: 53 patients) were included into the analysis. Patients' basic parameters, gonadotropin (Gn)-starting dose, total Gn-stimulation dosage, the number of retrieved and mature oocytes as well as in the hormonal parameters on the day of trigger (DoT) were not statistically significantly different. However, through stepwise Gn-reduction of 12.5 IU/day in the SG, there was a statistically highly significant difference in the Gn-stimulation dosage on the day of trigger (p < 0.0001) and statistically significant associations for the DoT-P4-levels with the DoT-FSH-levels for both groups (CG: p = 0.001; SG: p = 0.0045). The herein described significant associations between DoT-P4-levels and DoT-FSH-levels confirm the theory that enhanced FSH stimulation is the primary source of progesterone elevation on the day of final oocyte maturation in stimulated IVF/ICSI cycles. Given the pathophysiologic mechanism of progesterone elevation during ovarian stimulation, the use of an increased FSH step-down dosage should be studied in future RCTs, despite the fact that a step-down approach of daily 12.5 IU rec-FSH did not achieve a significantly reduced progesterone level on the DoT.

Abstract
Unlike poor ovarian response, despite being predicted to be normal responders based on their ovarian reserve markers, many patients respond suboptimally to ovarian stimulation. Although we can improve the number of retrieved oocytes by increasing the recombinant FSH dose and adding LH, the effect of suboptimal ovarian response on cumulative live birth rate (CLBR) and offspring safety is unclear. This study focuses on the unexpected suboptimal response during ovulation induction, and its causes and outcomes are analysed for the first time with a large amount of data used to compare the cumulative pregnancy rate (CPR), CLBR and offspring safety of patients with one complete ART cycle with all embryos used. Our analysis included 5218 patients treated with the GnRH agonist long protocol for their first IVF-embryo transfer (ET) cycles. Patients were divided into two groups according to whether the ovarian response was suboptimal. Propensity score matching (PSM) was utilized for sampling at up to 1:1 nearest-neighbour matching with caliper 0.05 to balance the baseline and improve comparability between the groups. Results showed that age, BMI and basal FSH were independent risk factors for slow response; the initial dosage of Gn, FSH on the first day of Gn, and LH on the first day of Gn were independent protective factors for suboptimal response. Suboptimal responders were also more likely to have irregular menses. Regarding the clinical pregnancy rate of the fresh IVF/ICSI-ET cycles, the adjusted results of the two groups were not significantly different. There was no difference in the CPR, CLBR, or offspring safety-related data, such as gestational age, preterm delivery rate, birthweight, birth-height and Apgar Scores between the two groups after PSM. Age-related changes in the number of oocytes retrieved from women aged 20-40 years old between the two groups were different, indicating that suboptimal response in elderly patients suggests a decline in ovarian reserve. Although we can now improve the outcomes of suboptimal responders, it increases the cost to the patients and the time to live birth, which requires further attention.

Abstract
STUDY QUESTION Is there an association between progesterone (P4) levels on the day of hCG or GnRH trigger and on the day of oocyte retrieval in IVF/ICSI cycles? SUMMARY ANSWER A significant positive correlation between P4 levels on the day of trigger and the day of oocyte retrieval is seen; HCG trigger induces a steeper P4 increase than GnRHa trigger. WHAT IS KNOWN ALREADY FSH induces LH receptor (LHR) expression on granulosa cells, and LHR produces progesterone when exposed to LH-like activity. FSH per se also to some extent induces P4 secretion. Late follicular phase progesterone rise has been associated with reduced reproductive outcomes. STUDY DESIGN, SIZE, DURATION This study is based on data from a previously published RCT conducted from 2009 to 2011. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 384 participants were enrolled; 199 received 5000 IU hCG and 185 received buserelin 0.5 mg for triggering ovulation. P4 was measured on the day of ovulation induction and on the day of oocyte retrieval. FSH consumption and number of retrieved follicles were recorded. MAIN RESULTS AND THE ROLE OF CHANCE A significant linear relationship between P4 on the day of ovulation induction and oocyte retrieval was seen in the hCG trigger group (P < 0.00001) as well as in the GnRHa trigger group (P < 0.00001). The P4 ratio (the increase in P4 between ovulation induction and oocyte retrieval) was significantly higher in the group of patients with <5 follicles compared to those with 5-15 and >15 follicles (P < 0.0001). The FSH consumption per follicle was significantly higher in the group of patients with <5 follicles compared to those with 5-15 and >15 follicles (P < 0.0001). LIMITATIONS, REASONS FOR CAUTION Although the study demonstrates a significant correlation between P4 levels before and after ovulation trigger, it does not demonstrate a causal relation to the number of LHRs present on granulosa cells. WIDER IMPLICATIONS OF THE FINDINGS The findings of this study support the proposed hypothesis that follicles exposed to high levels of FSH during ovarian stimulation will respond with an inappropriately high LHR expression. This in turn causes a high P4 output in response to the trigger. This study further expands our understanding of the underlying mechanisms affecting reproductive outcomes in relation to ovarian stimulation. STUDY FUNDING/COMPETING INTEREST(S) The authors received no specific funding for this work and disclose no conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
OBJECTIVE Progesterone elevation on the day of human chorionic gonadotropin (hCG) administration remains one of the most controversial topics in reproductive endocrinology. Factors associated with these increases have not been fully determined. The purpose of our study is to investigate factors associated with extreme progesterone elevation on the day of human chorionic gonadotropin (hCG) administration. MATERIALS AND METHODS This retrospective observational, single-center cohort study recruited 2000 fresh in vitro fertilization (IVF) and/or intracytoplasmic sperm injection(ICSI)-embryo transfer cycles from January 2000 to December 2014 in our institution. RESULTS When cycles were divided into those with progesterone <1.94 ng/mL (n = 1791) and ≧1.94 ng/mL (n = 209) on the day of hCG administration, five factors were positively associated with highly elevated progesterone concentration: protocol (GnRH agonist versus antagonist; odds ratio [OR = 2.786]), number of dominant follicles (OR = 1.098), total dose of follicle stimulating hormone (FSH) used (OR = 1.023), elevated luteinizing hormone (LH) (OR = 1.085) and estradiol (E2; OR = 1.001) concentrations on the day of hCG administration (p < 0.001 each). After omitting the protocol effect, the remaining factors showed limited contributions to highly elevated progesterone (ORs = 0.95-1.2). CONCLUSIONS The factor showing the greatest association with extreme progesterone elevation was use of the GnRH agonist protocol.

Abstract
Background It is debated whether the use of recombinant follicle-stimulating hormone (r-FSH) or human menopausal gonadotropin (HMG) is associated with progesterone (P) elevation in the late follicular phase. Aims The aim is to determine whether the type of gonadotropin used for controlled ovarian stimulation (COS) in in vitro fertilization (IVF) is associated with P elevation in the late follicular phase using antagonist protocol. Setting and Design This was a retrospective data analysis in the IVF unit. Methods Data of women who underwent COS between January 2005 and December 2017. Statistical Analysis Chi-square and unpaired Student's t-test in SPSS 20. Results Data of 439 women was analyzed. Mean age was 31.45 ± 4.6 years. HMG was used in 193 (44%), r-FSH in 232 (52.8%), and a combination of both in 14 (3.2%) women. Proportion of women with elevated P was significantly higher in r-FSH group as compared to HMG group (19/232 [8.2%] vs. 6/193 [3.1%]; P = 0.027). Mean P levels were significantly higher in r-FSH group (0.75 ng/ml vs. 0.59 ng/ml; P = 0.049). Mean estradiol (E2) levels at trigger were significantly higher in women with elevated P as compared to normal P (2893.4 ± 2091.8 pg/ml vs. 1668.3 ± 1508.6 pg/ml respectively; P < 0.000). Fresh embryo transfers performed in 18/27 women with elevated P resulted in pregnancy in three (16.7%) women. Two had biochemical pregnancies and one was lost to follow-up. Conclusions Use of r-FSH and E2 levels at trigger are associated with elevated P levels in the late follicular phase. Fresh embryo transfers performed in spite of elevated P levels were associated with low pregnancy rates and unfavorable outcomes.

Abstract
Elevated progesterone levels on the day of trigger negatively impact the outcome of assisted reproductive technique (ART) treatment and forced ovarian stimulation might be a cause of progesterone elevation during ovarian stimulation. To analyze the impact of forced and prolonged stimulation on the progesterone elevation, this data analysis from the Ensure study compared hormonal stimulation with corifollitropin alpha (CFA)-only with CFA plus recombinant (rec) follicle-stimulating hormone (FSH) after day 8 (CFA-plus group) of ovarian stimulation. In the Ensure study, 268 patients underwent ovarian stimulation with 100 µg CFA and 128 patients with recombinant FSH. A total of 35 patients (13.1%) from the CFA-arm received the hCG trigger after stimulation with CFA-only, 233 patients (86.9%) needed additional rec FSH from day 8 onwards to meet the criteria for trigger. Progesterone levels >0.8 ng/ml on the trigger day occurred in 90 patients (38.6%) from the CFA plus FSH group and only in one patient (2.8%) in the CFA-only group (p < .001). The ongoing pregnancy rate (OPR) was 31.4% (11/35) for patients in the CFA-only group and 24.5% (57/233) for patients CFA-plus group with additional recFSH after day 8 (p = .378). This set of data demonstrates that prolongation of stimulation in combination with intense stimulation leads to a statistically significant increased incidence of progesterone elevation on the day of trigger.

Abstract
'Poor responders' is a term used to describe a subpopulation of IVF patients who do not respond well to ovarian stimulation with gonadotrophins. While there is no standard definition of a poor responder, these patients tend to be of advanced maternal age (≥40 years), have a history of poor ovarian response with conventional stimulation protocols, and/or have low ovarian reserve. Despite the heterogeneity of this patient group, there are characteristics and needs common to many poor responders that can be addressed through a holistic approach. Stimulation during the earlier stages of follicle maturation may help synchronize follicle development for improved response to later gonadotrophin stimulation, and supplementation with dehydroepiandrosterone or human growth hormone may promote early follicle development in poor responders. IVF protocols should be specifically tailored to poor responders to complement the patient's natural cycle. Because poor responders tend to have high levels of stress and anxiety, patients should receive psychological counselling and support, both prior to and during IVF cycles, to ensure optimal outcomes and improve patients' experience. It is important to set realistic expectations with poor responders and their partners to help patients make informed decisions and better manage their distress and anxiety.

Abstract
SETTING Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) act on the same receptor, activating different signal transduction pathways. The role of LH or hCG addition to follicle-stimulating hormone (FSH) as well as menopausal gonadotropins (human menopausal gonadotropin; hMG) in controlled ovarian stimulation (COS) is debated. OBJECTIVE To compare FSH + LH, or FSH + hCG or hMG vs. FSH alone on COS outcomes. DESIGN A meta-analysis according to PRISMA statement and Cochrane Collaboration was performed, including prospective, controlled clinical trials published until July 2016, enrolling women treated with FSH alone or combined with other gonadotropins. Trials enrolling women with polycystic ovarian syndrome were excluded (PROSPERO registration no. CRD42016048404). RESULTS Considering 70 studies, the administration of FSH alone resulted in higher number of oocytes retrieved than FSH + LH or hMG. The MII oocytes number did not change when FSH alone was compared to FSH + LH, FSH + hCG, or hMG. Embryo number and implantation rate were higher when hMG was used instead of FSH alone. Pregnancy rate was significantly higher in FSH + LH-treated group vs. others. Only 12 studies reported live birth rate, not providing protocol-dependent differences. Patients' stratification by GnRH agonist/antagonist identified patient subgroups benefiting from specific drug combinations. CONCLUSION In COS, FSH alone results in higher oocyte number. HMG improves the collection of mature oocytes, embryos, and increases implantation rate. On the other hand, LH addition leads to higher pregnancy rate. This study supports the concept of a different clinical action of gonadotropins in COS, reflecting previous in vitro data.

Abstract
Objective Elevated serum progesterone (P) levels on triggering day have been known to affect the pregnancy rate of in vitro fertilization (IVF). This study aimed to identify the possible factors influencing serum P levels on triggering day in stimulated IVF cycles. Methods Three hundred and thirty consecutive fresh IVF cycles were included in the study. All cycles were first attempts and were performed in a single infertility center. The indications for IVF were male factor infertility (n=114), ovulatory infertility (n=84), endometriosis (n=61), tubal infertility (n=59), unexplained infertility (n=41), and uterine factor infertility (n=39). A luteal long protocol of a gonadotropin-releasing hormone (GnRH) agonist (n=184) or a GnRH antagonist protocol (n=146) was used for pituitary suppression. Ovarian sensitivity was defined as the serum estradiol level on triggering day per 500 IU of administered gonadotropins (OS[a]) or the retrieved oocyte number per 500 IU of administered gonadotropins (OS[b]). Results Univariate analysis revealed that the serum P level on triggering day was associated with the serum estradiol level on triggering day
(r=0.379, p<0.001), the number of follicles ≥14 mm (r=0.247, p<0.001), the number of retrieved oocytes (r=0.384, p<0.001), and ovarian sensitivity (OS[a]: r=0.245, p<0.001; OS[b]: r=0.170, p=0.002). The woman's age, body mass index, antral follicle count, and basal serum follicle stimulating hormone and estradiol levels were not associated with serum P level on triggering day. The serum P level on triggering day did not show significant variation depending on the type or cause of infertility, pituitary suppression protocol, or the type of gonadotropins used. Conclusion The serum P level on triggering day was closely related to the response to ovarian stimulation.

Abstract
INTRODUCTION Advanced fertilization techniques like frozen embryo transfer (FET) and assisted reproductive technology have become popular and commonly used methods to treat patients suffering from infertility. Incidences of infertility are on a rise due to increased representation of females in the work place, delay in marriages, stress, and ignorance. METHODS We performed this prospective therapeutic study to compare FET and fresh embryo transfer in the treatment of infertility in terms of conception rate, patient acceptance, complications, and patient's compliance. A prospective screening therapeutic study on 108 patients, from September 2013 to September 2014 in Karnataka, India, randomized the patients into 2 groups (n = 54), Group-I treated with day-3 FET while Group-II was treated with fresh embryo transfer, after performing ICSI. RESULTS In 108 patients, 45 % patients were within 35 years of age, 35 % were in the age group 35-39. Significantly, 22 (40.75 %) patients treated with FET conceived (P = 0.022), whereas 16 (29.63 %) patients treated with fresh embryo transfer conceived (P = 0.59). DISCUSSION There is limited published literature from the subcontinent, comparing techniques like FET and embryo transfers in the treatment of infertility. Awareness and economic reforms must be formulated in India to facilitate individuals facing infertility problems to conceive. CONCLUSION FET has better and significant conception rates compared to fresh embryo transfers. FET shares an advantage of providing good quality embryos for future and subsequent implantations in cases of failure. Patient counseling and motivation play a pivotal role in the success of therapeutic procedure.

Abstract
OBJECTIVES Clarifying whether the addition of recombinant LH (rLH) to recombinant FSH (rFSH) leads to progesterone (P4) levels on dhCG comparable to those obtained with stimulation with FSH and hCG (HP-hMG) MATERIALS AND METHODS: Pituitary-desensitized patients, matched for age and follicle reserve, received rFSH+LH (n=729) or HP-hMG (n=729). In the rFSH+rLH group, rLH (75 UI/day) was started at day 6. To control for the influence of ovarian response on P4, we divided serum P4 levels by the number of growing follicles (13-22 mm; "per follicle" P4 levels) and performed a multivariate analysis. RESULTS Serum P4 levels on dHCG were lower in the HP-hMG (median: 0.63 ng/mL, max-min: 0.10-2.97) than in the rFSH+rLH group (0.91 ng/mL; 0.10-4.65, P<0.0001), as well as "per-follicle" P4 levels (0.055 ng/mL/growing follicle, 0.006-0.284 vs 0.077 ng/mL/growing follicle, 0.003-0.336; P<0.0001). CONCLUSIONS HP-hMG led to lower P4 levels on day hCG than rFSH+rLH irrespective of the intensity of the ovarian response and the adjunction of rLH (75 IU/day from day 6 onward).

Abstract
Luteinizing hormone (LH) in synergy with follicle stimulating hormone (FSH) stimulates normal follicular growth and ovulation. FSH is frequently used in assisted reproductive technology (ART). Recent studies have facilitated better understanding on the complementary role of the LH to FSH in regulation of the follicle; however, role of LH in stimulation of follicle, optimal dosage of LH in stimulation and its importance in advanced aged patients has been a topic of discussion among medical fraternity. Though the administration of exogenous LH with FSH is obligatory for controlled ovarian stimulation in patients with hypogonadotropic hypogonadism, there is still a paucity of information of its usage in other patient population. In this review we looked in to the multiple roles that LH plays complementary to FSH to better understand the LH requirement in patients undergoing ART.

Abstract
OBJECTIVE To examine the available evidence to assess if cryopreservation of all embryos and subsequent frozen embryo transfer (FET) results in better outcomes compared with fresh transfer. DESIGN Systematic review and meta-analysis. SETTING Centers for reproductive care. PATIENT(S) Infertility patient(s). INTERVENTION(S) An exhaustive electronic literature search in MEDLINE, EMBASE, and the Cochrane Library was performed through December 2011. We included randomized clinical trials comparing outcomes of IVF cycles between fresh and frozen embryo transfers. MAIN OUTCOME MEASURE(S) The outcomes of interest were ongoing pregnancy rate, clinical pregnancy rate, and miscarriage. RESULT(S) We included three trials accounting for 633 cycles in women aged 27-33 years. Data analysis showed that FET resulted in significantly higher ongoing pregnancy rates and clinical pregnancy rates. CONCLUSION(S) Our results suggest that there is evidence that IVF outcomes may be improved by performing FET compared with fresh embryo transfer. This could be explained by a better embryo-endometrium synchrony achieved with endometrium preparation cycles.

Abstract
STUDY QUESTION During controlled ovarian stimulation (COS), does the duration of premature serum progesterone (P) elevation before administration of hCG affect the outcomes of IVF/ICSI embryo transfer (-ET) cycles? SUMMARY ANSWER The duration of the premature serum P elevation is inversely related to the clinical pregnancy rate of IVF/ICSI-ET cycles. WHAT IS KNOWN AND WHAT THIS PAPER ADDS The majority of the previous studies only considered a single serum P measurement made on the day of hCG administration and the results of attempts to relate this to IVF/ICSI-ET outcomes were controversial. However, the effect of the duration of premature serum P elevation before the hCG administration on the outcomes of IVF/ICSI-ET cycles has not been studied well. Here we demonstrate that the duration of premature serum P elevation has a more significant inverse correlation than the absolute serum P concentration on the day of hCG administration with IVF/ICSI-ET outcomes. DESIGN It is a retrospective, single-centre cohort study. A total of 1784 IVF and/or ICSI-ET cycles were included from October 2005 to June 2011. PARTICIPANTS AND SETTING A total of 1784 patients underwent their IVF and/or ICSI-ET cycles in a university hospital IVF unit. The inclusion criteria include (i) age between 20 and 42 years and (ii) eligible indications for COS before IVF/ICSI. MAIN RESULTS AND THE ROLE OF CHANCE The duration of premature serum P elevation to >1 ng/ml is significantly inversely associated with the probability of clinical pregnancy (odds ratio = 0.773, 95% confidence interval: 0.660-0.891, P < 0.001), after adjustment for possible confounders with multivariate logistic regression analysis. However, the significance of inverse correlation between the absolute serum P concentration on the day of hCG administration with clinical pregnancy rate decreased after adjustment. BIAS, CONFOUNDING AND OTHER REASONS FOR CAUTION The cutoff value we chose to define premature serum P elevation (P > 1.0 ng/ml) might not be able to be applied to different immunoassay kits and study population. The retrospective nature of this study inevitably might be influenced by some selection bias. GENERALIZABILITY TO OTHER POPULATIONS Older patients (>42 years) are excluded from our study.

Abstract
OBJECTIVE To evaluate the effect of recombinant LH in assisted reproduction technology (ART) cycles in patients of advanced reproductive age. DESIGN A systematic review and meta-analysis. SETTING Published randomized controlled clinical trials comparing recombinant LH plus recombinant FSH versus recombinant FSH only in patients of advanced reproductive age. PATIENT(S) Patients 35 years and older undergoing assisted reproduction. INTERVENTION(S) Recombinant LH plus recombinant FSH controlled ovarian hyperstimulation (COH) versus recombinant FSH stimulation only in assisted reproduction cycles. MAIN OUTCOME MEASURE(S) Implantation and clinical pregnancy. RESULT(S) Seven trials were identified that met inclusion criteria and comprised 902 assisted reproduction technology cycles. No differences in serum E(2) on the day of hCG administration were reported in any trials. Two trials reported lower oocyte yield and one trial reported lower metaphase II oocyte yield in the recombinant LH-supplemented group. One trial reported higher fertilization rates in the recombinant LH-supplemented group. In a fixed effect model, implantation was higher in the recombinant LH-supplemented group (odds ratio 1.36, 95% confidence interval 1.05-1.78). Similarly, clinical pregnancy was increased in the recombinant LH-supplemented group (odds ratio 1.37, 95% confidence interval 1.03-1.83). CONCLUSION(S) The addition of recombinant LH to ART cycles may improve implantation and clinical pregnancy in patients of advanced reproductive age.

Abstract
OBJECTIVE To compare the efficacy and safety of highly purified menotropin (hphMG) and recombinant FSH (rFSH) for controlled ovarian stimulation in a GnRH antagonist cycle with compulsory single-blastocyst transfer. DESIGN Randomized, open-label, assessor-blind, parallel groups, multicenter, noninferiority trial. SETTING Twenty-five infertility centers in seven countries. PATIENT(S) Seven hundred forty-nine women. INTERVENTION(S) Controlled ovarian stimulation with hphMG or rFSH in a GnRH antagonist cycle with compulsory single-blastocyst transfer on day 5 in one fresh or subsequent frozen blastocyst replacement in natural cycles initiated within 1 year of each patient's start of treatment. MAIN OUTCOME MEASURE(S) Ongoing pregnancy (primary end point) and live birth rates, as well as pharmacodynamic parameters. RESULT(S) The ongoing pregnancy rate after a fresh cycle was 30% with hphMG versus 27% with rFSH for the per-protocol (PP) population and 29% versus 27% for the intention-to-treat (ITT) population. Noninferiority of hphMG compared to rFSH was established. Considering frozen cycles initiated within 1 year, the cumulative live birth rate for a single stimulation cycle was 40% and 38% for women treated with hphMG and rFSH, respectively (both PP and ITT). Significant differences in pharmacodynamic end points were found between the two gonadotropin preparations. CONCLUSION(S) Highly purified hMG is at least as effective as rFSH in GnRH antagonist cycles with compulsory single-blastocyst transfer. CLINICAL TRIAL REGISTRATION NUMBER NCT00884221.

Abstract
During recent decades minor innovative drugs have been developed for the female contraceptive market and they all contain steroidal progestagens (and estrogens) that act centrally and have side effects that can be attributed to this central action. In this study, we present an innovative tissue-specific approach for female contraception by low molecular weight (LMW) FSH receptor (FSHR) agonists, which interact with the FSHR that is dominantly expressed in the granulosa cells. The oral administration of LMW FSHR agonists with a short circulation time, induced formation of luteinized unruptured follicles (LUFs) from the Graafian follicles, thereby preventing the release of the oocyte. The short-acting LMW FSHR compounds were fully agonistic to FSHR (EC50=4–5 nM). In an isolated mouse follicle culture, a short incubation period (2 h) resulted in inhibition of follicular rupture, where continuous incubation induced follicle growth. Pharmacokinetics after oral administration showed a surge-like exposure in rats and monkeys. Oral administration of short-acting LMW FSHR agonists inhibited ovulation at 10 mg/kg in rats and guinea pigs by generating LUFs without affecting cyclicity. Also, inhibition of follicular rupture was shown to be reversible within one cycle. Finally, LUFs were induced without affecting the hormonal cyclicity in cynomolgus monkeys, a mono-ovulatory species. In healthy women LUF formation occurs naturally, with a LUF acting as corpus luteum that produces enough progesterone to ensure normal menstrual cyclicity. Together with the presented data this indicates that the innovative approach with short-acting LMW FSHR agonists could lead to oral contraception for females at the ovarian level.

Abstract
BACKGROUND The influence of LH on serum progesterone rise during gonadotrophin stimulation is a matter of debate. The purpose of this analysis was to assess the impact of supplementation with 'LH activity' products on serum progesterone changes before hCG administration in GnRH analog-treated women. METHODS A computerized literature search was performed to identify studies comparing FSH treatment alone to those that provided supplementation with 'LH activity' using hMG, recombinant (r)LH (rLH) or hCG in GnRH analog protocols. Data regarding stimulation regimens were extracted from those that reported serum progesterone levels at the time of hCG in order to assess the specific role of LH activity products. RESULTS Serum progesterone determination at the time of hCG administration was performed in 34 out of 108 studies comparing the effects of FSH alone or in combination with LH activity products. In a vast majority, no significant difference in serum progesterone could be found between stimulation regimens. However, in four studies where LH activity (three hMG and one rLH) was administered from the beginning of ovarian stimulation, serum P-values were significantly decreased. In contrast, in two studies where LH activity (hCG) was provided during the late follicular phase, serum P-values were significantly increased. Analysis of confounding factors showed that the intensity of ovarian stimulation is the most important determining factor to explain serum progesterone elevation at the time of hCG administration, CONCLUSIONS This systematic review shows that providing LH activity supplementation in combination with FSH during ovarian stimulation does not have a consistent effect on serum progesterone concentrations at the time of hCG administration. However, these data also suggest that, in accordance with physiological concept, the timing of LH activity administration could influence the impact on serum progesterone changes.

Abstract
Aim of this study was to assess the efficacy of recombinant luteinizing hormone (rLH) supplementation in late follicular phase in multiple follicular stimulation with recombinant follicle stimulating hormone (rFSH) in Triptoreline down-regulated patients undergoing IVF, on preventing clinical OHSS and cycles cancellation for OHSS risk. Nine hundred ninety-nine patients aged ≤ 40 with basal FSH ≤ 12 mUI/Ml were down-regulated before starting rFSH stimulation for oocytes recovery. Patients were allocated in two groups: (A) (501 patients) treated with 150 IU of rFSH eventually adjusting rFSH dosage day 7 of stimulation until recombinant human chorionic gonadotropin (rhCG) administration, (B) (498 patients) treated with 150 IU of rFSH and 75 IU of rLH since day 7 of stimulation until rhCG administration and adjusting rFSH at the same day. E2 the day of rhCG was higher in group B (p < 0.0001); number of cycles cancelled in group A (42/8.3%) for risk of ovarian hyperstimulation syndrome (OHSS) was higher than group B (12/2.4%) (p < 0.000001). We observed an increase in pregnancies in group B compared with group A (16.8% vs 11.9%) (p < 0.05) and we observed also a larger number of clinical OHSS in group A than in group B (p < 0.05).

Abstract
OBJECTIVE Gonadotropins used in controlled ovarian stimulation have been increasing in number. Beside the recombinant preparations such as rec-FSH, rec-LH and h-hMG human-derived preparations have entered the market. We decided to compare the effects of rec-FSH and HP-hMG with GnRHa on embryo quality and pregnancy outcome in women undergoing an IVF cycle. MATERIAL AND METHODS In this study, data of 87 patients who had applied to our center from 2007 to 2008 and who had met all inclusion criteria, were analyzed. The patients underwent controlled ovarian hyperstimulation with HP-hMG, rec-FSH following down-regulation with a GnRHa in a long protocol, selected according to determined criteria and acquired embryo via IVF transfer. RESULTS Of the 87 patients, 44 were stimulated with rec-FSH and 43 with HP-hMG. Distribution of infertility causes was similar between the groups. Duration of gonadotropin administration (p=0.677, Student's t-test) and the total dose of gonadotropin received (p=0.392, Student's t-test) were similar between the two groups. The fertilization rate of the rec-FSH group was significantly higher than the HP-hMG group (p=0.001, Mann-Whitney U test). No significant differences were observed between the study groups in biochemical, clinical and ongoing pregnancy parameters. CONCLUSION The higher oocyte yield with rec-FSH does not result in higher quality embryos. LH activity in combination with FSH activity positively affected the oocyte and embryo maturation. Therefore, when we consider the clinical and ongoing pregnancy rates there is no inferiority of HP-hMG in controlled ovarian stimulation.

Abstract
OBJECTIVE In assisted reproductive techniques it is important to find a balance between high pregnancy and acceptable multiple pregnancy rates. In IVF treatment, stimulation with highly purified human menopausal gonadotropin (hMG) results in comparable or even higher pregnancy rates at lower oocyte yields compared to recombinant FSH. Since highly purified hMG contains LH activity, a number of the advantages of highly purified hMG may be attributed to this LH activity. In IUI treatment the effectiveness of highly purified hMG has been barely investigated. The aim of this study was to examine the effectiveness of highly purified hMG in IUI patients treated with a mild stimulation protocol. STUDY DESIGN In this retrospective study 378 patients were included, receiving 1400 IUI cycles between January 2006 and December 2007. Patients were first treated with three subsequent natural cycles without controlled ovarian hyperstimulation, followed by three subsequent cycles stimulated with highly purified hMG. Primary outcomes were ongoing pregnancy rate and multifollicular growth. Secondary outcomes were multiple pregnancy and miscarriage rates. Primary and secondary outcomes were expressed in percentages with associated 95% confidence intervals (95%CI). Differences in the outcomes between natural and stimulated cycles were calculated using χ(2) tests. Statistical differences were determined at P < 0.05. RESULTS Ongoing pregnancy rates increased from 6% (95%CI 4.7-7.7) per natural cycle to 7.4% (95%CI 5.2-10.3) per highly purified hMG stimulated cycle (p = 0.34). The highest ongoing pregnancy rate was observed in the fifth treatment cycle (10.8% (95%CI 6.6-17)), which is significantly higher than the ongoing pregnancy rate in the unstimulated group (p = 0.03). In the highly purified hMG group three (9.7% (95%CI 3.3-24.9)) of the ongoing pregnancies were twin pregnancies, in the unstimulated group there was one (1.7% (95%CI 0.3-9.0)) twin pregnancy (p = 0.08). CONCLUSION Our results indicate that mild stimulation with highly purified hMG in IUI treatment results in an acceptable balance between ongoing and multiple pregnancy rates. Future prospective trials should compare mild stimulation protocols to protocols directly starting with controlled ovarian hyperstimulation. Furthermore, these trials should compare other types and dosages of gonadotropins.

Abstract
OBJECTIVE To analyze the impact of LH administration on cycle outcome in ovarian stimulation with GnRH antagonists. DESIGN Randomized, open-label, controlled trial performed in two age subgroups. Recombinant (r) FSH versus rFSH + rLH administration was compared. SETTING University-affiliated private infertility clinic. PATIENT(S) Up to 35 years old (n = 380) and aged 36 to 39 years (n = 340), undergoing their first or second IVF cycle. INTERVENTION(S) Recombinant LH administration since stimulation day 1. MAIN OUTCOME MEASURE(S) Implantation rate, ongoing pregnancy rate. RESULT(S) In the young population, implantation rates were similar: 27.8% versus 28.6%, odds ratio (OR) 1.03 (95% confidence interval [CI] 0.73-1.47), as was the ongoing pregnancy rate per started cycle: 37.4% versus 37.4%, OR 1.0 (95% CI 0.66-1.52). In older patients, the implantation rate was significantly higher in the rFSH + rLH group: 26.7% versus 18.6%, OR 1.56 (95% CI 1.04-2.33). Ongoing pregnancy rates per started cycle were 33.5% versus 25.3%, OR 1.49 (95% CI 0.93-2.38). CONCLUSION(S) Recombinant LH administration significantly increased the implantation rate in patients aged 36 to 39 years. A clinically relevant better ongoing pregnancy rate per started cycle was observed, although the difference was not statistically significant. Patients younger than 36 years do not obtain any benefit from rLH administration.

Abstract
Premature luteinization (PL) refers to a rise in serum progesterone (P) levels on the day of hCG administration. Most studies used an absolute P level on the day of hCG administration as an indicator of PL, and the cutoff level differed from 0.8 to 2 ng/mL. Some authors defined PL as a P/E2 ratio of >1. There is a marked variation in the incidence (13% to 71%), of PL due to discrepancies in definition, population characteristics and/or treatment protocols. The pathogenesis of PL in COH is still poorly understood. Several hypotheses may be considered to explain this phenomenon: elevation of follicular LH levels, serum accumulation of HCG from HMG, increased LH receptor sensitivity of the granulosa cells to FSH, or poor ovarian response with increased LH sensitivity. The consequences of this premature elevation of serum P on IVF outcome remain controversial. Attempts to prevent COH include: use of Low-dose hCG alone in the late COH stages, flexible antagonist protocol, use of mifepristone, aspiration of a single leading follicle, hCG administration when the levels of serum P exceeded 1.0 ng/mL.
