Recombinant human luteinizing hormone increases endometrial thickness in women undergoing assisted fertility treatments: a systematic review and meta-analysis. Front Pharmacol 2024; 15:1434625. [PMID: 39135787 PMCID: PMC11317380 DOI: 10.3389/fphar.2024.1434625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2024] [Accepted: 07/11/2024] [Indexed: 08/15/2024] Open
Abstract
Introduction The optimal dosage of recombinant human luteinizing hormone (r-hLH) and its impact on endometrial thickness (EMT) when administered alongside recombinant human follicle-stimulating hormone (r-hFSH) during controlled ovarian stimulation (COS) for in vitro fertilization/intracytoplasmic sperm injection and embryo transfer are uncertain, which formed the aims of this systematic review and meta-analysis. Method A search was performed in PubMed, Cochrane Library, Web of Science, EMBASE, CNKI, and Wanfang from its inception to 10 July 2023. Twenty-seven Randomized controlled trials comparing r-hFSH/r-hLH co-treatment with r-hFSH alone during in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) were included. Pooled odds ratios (OR) for dichotomous data and mean differences (MD) for continuous data, with their respective 95% confidence intervals (CI), were generated. Meta-analysis employed fixed-effect or random-effect models based on heterogeneity, using Q-test and I2-index calculations. The main outcomes included EMT on trigger day, clinical pregnancy rate (CPR) and live birth rate (LBR). Results r-hFSH/r-hLH significantly increased EMT on trigger day (MD = 0.27; 95% CI, 0.11-0.42; I2 = 13%), but reduced oocyte number (MD = -0.60; 95% CI, -1.07 to -0.14; I2 = 72%) and high-quality embryos (MD = -0.76; 95% CI, -1.41 to -0.10; I2 = 94%) than r-hFSH alone, more pronounced with the gonadotrophin-releasing hormone agonist long protocol. A subgroup analysis showed r-hLH at 75 IU/day increased CPR (OR = 1.23; 95% CI, 1.02-1.49; I2 = 16%) and EMT on trigger day (MD = 0.40; 95% CI, 0.19-0.61; I2 = 0%). Participants ≥35 years of age exhibited decreased retrieved oocytes (MD = -1.26; 95% CI, -1.78 to -0.74; I2 = 29%), but an increase in EMT on trigger day (MD = 0.26; 95% CI, 0.11-0.42; I2 = 29%). Conclusion r-hFSH/r-hLH during COS significantly improved EMT compared to r-hFSH alone. An r-hLH dose of 75 IU/day may be considered for optimal pregnancy outcomes, which still require further clinical studies to support this dosing regime.

Recombinant LH supplementation improves cumulative live birth rates in the GnRH antagonist protocol: a multicenter retrospective study using a propensity score-matching analysis.

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

Abstract
Background This clinical trial aimed to compare the clinical efficacy of highly purified human menopausal gonadotropin (HP-HMG) plus recombinant human follicle-stimulating hormone (rFSH) versus rFSH alone on controlled ovarian stimulation (COS) in vitro fertilization-embryo transfer (IVF-ET). Methods A total of 610 women underwent long gonadotropin-releasing hormone (GnRH) agonist protocol for IVF treatment. The subjects were randomized into 2 groups: HP-HMG + rFSH group (n=305) and rFSH group (n=305). The main outcome was the progesterone (P) level on the day of HCG injection. Results There was no significant difference in terms of the demographic and baseline characters between the two groups. In rFSH group, the P level on the day of HCG trigger were significantly higher than that of HP-HMG+rFSH group (4.3±2.2 vs. 3.8±1.7 nmol/L, P<0.001). The fertilization rate in rFSH group was significantly lower than that of HP-HMG + rFSH group (69.2% vs. 73.9%, P<0.001). Simultaneously, the percentage of cycles with fresh embryo transfer in rFSH group was also significantly lower than that of HP-HMG + rFSH group (49.6% vs. 57.5%, P=0.007). However, there was no difference in terms of cleavage rate, implantation rate, clinical pregnancy rate and ovarian hyperstimulation syndrome (OHSS) rate between two groups. Conclusions The use of combined HP-HMG with FSH may be superior to rFSH alone in stimulating the ovary in normal responders undergoing IVF treatment. Furthermore, the further prospective studies with large sample are still needed to confirm the study.

Abstract
OBJECTIVE To study the role of recombinant human LH supplementation in women with hypo-response to ovarian stimulation. METHODS We performed a systematic review and meta-analysis of prospective clinical trials in which recombinant FSH monotherapy protocols were compared with LH-supplemented protocols in hypo-responders. A search was conducted of the Scopus, MEDLINE databases without time or language restrictions. Primary outcome was clinical pregnancy rate. RESULTS Significantly higher clinical pregnancy rates (odds ratio: 2.03, P = 0.003), implantation rates (odds ratio: 2.62, P = 0.004) and number of oocytes retrieved (weight mean differences: 1.98, P = 0.03) were observed in hypo-responders supplemented with recombinant LH versus hypo-responders who underwent FSH monotherapy. No differences in terms of mature oocytes or miscarriage rates were found between the two groups. CONCLUSION In conclusion, our analysis confirms that women with a hypo-response to exogenous gonadotropins might benefit from LH supplementation. However, more trials are required before a definitive conclusion can be drawn.

Abstract
OBJECTIVE To assess the role of recombinant human LH (r-hLH) supplementation in ovarian stimulation for ART in specific subgroups of patients. DESIGN Systematic review. SETTING Centers for reproductive care. PATIENT(S) Six populations were investigated: 1) women with a hyporesponse to recombinant human FSH (r-hFSH) monotherapy; 2) women at an advanced reproductive age; 3) women cotreated with the use of a GnRH antagonist; 4) women with profoundly suppressed LH levels after the administration of GnRH agonists; 5) normoresponder women to prevent ovarian hyperstimulation syndrome; and 6) women with a "poor response" to ovarian stimulation, including those who met the European Society for Human Reproduction and Embryology Bologna criteria. INTERVENTION(S) Systematic review. MAIN OUTCOME MEASURE(S) Implantation rate, number of oocytes retrieved, live birth rate, ongoing pregnancy rate, fertilization rate, and number of metaphase II oocytes. RESULT(S) Recombinant hLH supplementation appears to be beneficial in two subgroups of patients: 1) women with adequate prestimulation ovarian reserve parameters and an unexpected hyporesponse to r-hFSH monotherapy; and 2) women 36-39 years of age. Indeed, there is no evidence that r-hLH is beneficial in young (<35 y) normoresponders cotreated with the use of a GnRH antagonist. The use of r-hLH supplementation in women with suppressed endogenous LH levels caused by GnRH analogues and in poor responders remains controversial, whereas the use of r-hLH supplementation to prevent the development of ovarian hyperstimulation syndrome warrants further investigation. CONCLUSION(S) Recombinant hLH can be proposed for hyporesponders and women 36-39 years of age.

Abstract
The potential effects of high basal luteinizing hormone (LH) levels on human reproduction were controversial. To demonstrate the effects of elevated basal LH levels on the outcome of patients undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles, we performed a retrospective data analysis of 1011 polycystic ovarian syndrome (PCOS) patients treated with human menopausal gonadotropin and medroxyprogesterone acetate (hMG + MPA) protocol at our center between Nov. 2013 and Jun. 2017. PCOS patients with elevated basal LH levels had significantly higher LH exposure during the stimulation period. The group with LH ≥ 10 mIU/mL showed a lower mean total hMG dose used but higher numbers of oocytes retrieved, metaphase II oocytes, embryos and top-quality embryos developed than the groups with lower basal LH levels. Moreover, partial correlation analysis showed that the basal LH level was negatively correlated with the total hMG dose but positively correlated with the numbers of oocytes retrieved, metaphase II oocytes, embryos, and top-quality embryos. There were no significant differences in the rates of oocyte retrieval, fertilization, implantation, clinical pregnancy and miscarriage between the groups based on frozen embryo transfer (FET). We concluded that elevated basal LH level does not impair the final outcome of hMG + MPA-treated IVF/ICSI cycles in PCOS women.

Abstract
PURPOSE Premature luteinization (PL) affects 12.3-46.7% of fresh in vitro fertilization cycles, and there is accumulating evidence confirming its negative effect on success rates. However, despite its clinical significance, PL is poorly understood and defined. This narrative review aims to provide a fresh look at the phenomenon of PL by summarizing the existing evidence and re-evaluating fundamental issues. METHODS A thorough electronic search was conducted covering the period from 1978 until January 2018 in PubMed, Embase, and Medline databases, and references of relevant studies were cross-checked. Meeting proceedings of the European Society of Human Reproduction and Embryology and the American Society for Reproductive Medicine were also hand searched. RESULTS In the curious case of PL, one should go back to the beginning and re-consider every step of the way. The pathogenesis, definition, measurement methods, clinical implications, and management strategies are discussed in detail, highlighting controversies and offering "food for thought" for future directions. CONCLUSIONS Authors need to speak the same language when studying PL in order to facilitate comparisons. The terminology, progesterone cut-off, measurement methods and days of measurement should be standardized and globally accepted; otherwise, there can be no scientific dialog. Future research should focus on specific patient profiles that may require a tailored approach. Progesterone measurements throughout the follicular phase possibly depict the progesterone exposure better than an isolated measurement on the day of hCG. Adequately powered randomized controlled trials should confirm which the best prevention and management plan of PL is, before introducing any strategy into clinical practice.

Abstract
Basic research into a possible link between serum and follicular fluid androgen concentrations to detemine whether androgen supplementation in low responders affects follicular endocrine milieu is still lacking. Ninety-seven women (aged 28-43 years) undergoing one natural IVF cycle without any hormone stimulation were analysed. Serum and follicular fluid were collected at the time of follicle aspiration, and the concentrations of LH, total testosterone, oestradiol, dehydroepiandrosterone and anti-Mullerian hormone (AMH) were determined. Serum LH (P = 0.003) and AMH (P = 0.026) concentrations, and follicular fluid AMH (P = 0.015) decreased with increasing age. Within follicular fluid, total testosterone was correlated with oestradiol (P < 0.001) and AMH (P = 0.010); LH correlated with AMH (P = 0.005). Correlation analysis of serum and follicular fluid hormone concentrations revealed that LH, oestradiol and AMH correlated (P < 0.001), whereas testosterone did not. Testosterone serum concentrations did not correlate with other follicular fluid hormones, such as dehydroepiandrosterone, oestradiol and AMH, whereas serum LH correlated with follicular flulid AMH (P < 0.008). Follicular fluid hormone concentrations seem to be independent from serum testosterone. Therefore, it is questionable whether an increase in serum testosterone concentration by androgen supplementation could improve the follicular endocrine milieu.

Abstract
BACKGROUND One of the various ovarian stimulation regimens used for in-vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) cycles is the use of recombinant follicle-stimulating hormone (rFSH) in combination with a gonadotrophin-releasing hormone (GnRH) analogue. GnRH analogues prevent premature luteinizing hormone (LH) surges. Since they deprive the growing follicles of LH, the question arises as to whether supplementation with recombinant LH (rLH) would increase live birth rates. This is an updated Cochrane Review; the original version was published in 2007. OBJECTIVES To compare the effectiveness and safety of recombinant luteinizing hormone (rLH) combined with recombinant follicle-stimulating hormone (rFSH) for ovarian stimulation compared to rFSH alone in women undergoing in-vitro fertilisation/intracytoplasmic sperm injection (IVF/ICSI). SEARCH METHODS For this update we searched the following databases in June 2016: the Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO and ongoing trials registers, and checked the references of retrieved articles. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing rLH combined with rFSH versus rFSH alone in IVF/ISCI cycles. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias, and extracted data. We combined data to calculate odds ratios (ORs) and 95% confidence intervals (CIs). We assessed statistical heterogeneity using the I2 statistic. We assessed the overall quality of the evidence for the main comparisons using GRADE methods. Our primary outcomes were live birth rate and incidence of ovarian hyperstimulation syndrome (OHSS). Secondary outcomes included ongoing pregnancy rate, miscarriage rate and cancellation rates (for poor response or imminent OHSS). MAIN RESULTS We included 36 RCTs (8125 women). The quality of the evidence ranged from very low to moderate. The main limitations were risk of bias (associated with poor reporting of methods) and imprecision.Live birth rates: There was insufficient evidence to determine whether there was a difference between rLH combined with rFSH versus rFSH alone in live birth rates (OR 1.32, 95% CI 0.85 to 2.06; n = 499; studies = 4; I2 = 63%, very low-quality evidence). The evidence suggests that if the live birth rate following treatment with rFSH alone is 17% it will be between 15% and 30% using rLH combined with rFSH.OHSS: There may be little or no difference between rLH combined with rFSH versus rFSH alone in OHSS rates (OR 0.38, 95% CI 0.14 to 1.01; n = 2178; studies = 6; I2 = 10%, low-quality evidence). The evidence suggests that if the rate of OHSS following treatment with rFSH alone is 1%, it will be between 0% and 1% using rLH combined with rFSH.Ongoing pregnancy rate: The use of rLH combined with rFSH probably improves ongoing pregnancy rates, compared to rFSH alone (OR 1.20, 95% CI 1.01 to 1.42; participants = 3129; studies = 19; I2 = 2%, moderate-quality evidence). The evidence suggests that if the ongoing pregnancy rate following treatment with rFSH alone is 21%, it will be between 21% and 27% using rLH combined with rFSH.Miscarriage rate: The use of rLH combined with rFSH probably makes little or no difference to miscarriage rates, compared to rFSH alone (OR 0.93, 95% CI 0.63 to 1.36; n = 1711; studies = 13; I2 = 0%, moderate-quality evidence). The evidence suggests that if the miscarriage rate following treatment with rFSH alone is 7%, the miscarriage rate following treatment with rLH combined with rFSH will be between 4% and 9%.Cancellation rates: There may be little or no difference between rLH combined with rFSH versus rFSH alone in rates of cancellation due to low response (OR 0.77, 95% CI 0.54 to 1.10; n = 2251; studies = 11; I2 = 16%, low quality evidence). The evidence suggests that if the risk of cancellation due to low response following treatment with rFSH alone is 7%, it will be between 4% and 7% using rLH combined with rFSH.We are uncertain whether use of rLH combined with rFSH improves rates of cancellation due to imminent OHSS compared to rFSH alone. Use of a fixed effect model suggested a benefit in the combination group (OR 0.60, 95% CI 0.40 to 0.89; n = 2976; studies = 8; I2 = 60%, very low quality evidence) but use of a random effects model did not support the conclusion that there was a difference between the groups (OR 0.82, 95% CI 0.34 to 1.97). AUTHORS' CONCLUSIONS We found no clear evidence of a difference between rLH combined with rFSH and rFSH alone in rates of live birth or OHSS. The evidence for these comparisons was of very low-quality for live birth and low quality for OHSS. We found moderate quality evidence that the use of rLH combined with rFSH may lead to more ongoing pregnancies than rFSH alone. There was also moderate-quality evidence suggesting little or no difference between the groups in rates of miscarriage. There was no clear evidence of a difference between the groups in rates of cancellation due to low response or imminent OHSS, but the evidence for these outcomes was of low or very low quality.We conclude that the evidence is insufficient to encourage or discourage stimulation regimens that include rLH combined with rFSH in IVF/ICSI cycles.

Abstract
We aimed to evaluate the clinical efficacy of r-LH supplementation to r-FSH in patients with suboptimal response to ovarian stimulation undergoing assisted reproduction with GnRH-a downregulation and stimulation with r-FSH. One-hundred thirty-seven patients were included in the study; among them 52 showed normal ovarian response to stimulation and composed the control group (Group 1), and 85 showed suboptimal response to stimulation and were divided into two groups. For Group 2 (n = 50), 75 IU/L r-LH was added to the treatment, for Group 3 (n = 35) r-FSH dose was increased by 75 IU/L. IVF results were compared between the groups. Implantation rates were 34.8% in control group, and 36.1% and 15% in LH supplementation group and increased-dose r-FSH group, respectively. Implantation rates were statistically significantly higher in Groups 1 and 2 compared to Group 3 (p < 0.02). Pregnancy rate was noticed in 64.7% of Group 1, 57.8% of Group 2 and at 32.4% of Group 3. Pregnancy rate was significantly higher in Group 2 than Group 3 (p < 0.05). r-LH supplementation is an option for improving IVF outcome in patients with suboptimal ovarian response to ovulation induction with r-FSH during GnRH agonist down-regulation. Particularly, r-LH is recommended as it may have a beneficial action on implantation in selected group.

Abstract
The objective of this meta-analysis is to assess the impact of LH supplementation in women undergoing in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI) with gonadotropin releasing hormone (GnRH) antagonist protocol. No significant difference in outcomes between LH supplementation and r-FSH alone in women undergoing IVF/ICSI with GnRH antagonist protocol is currently present, and further studies are necessary for more solid conclusions on pregnancy likelihood to be drawn.

Abstract
PURPOSE Down-regulation with gonadodropin-releasing agonist (GnRH-a) protocol during IVF stimulation leads to a severe endogenous LH suppression, which may affect the follicular development. The aim of the study was to evaluate the effects of recombinant LH (r-LH) administration, during late follicular development stages, in recombinant FSH (r-FSH) stimulated cycles on follicular fluid (FF) parameters and on cumulus cell quality. METHODS Twenty patients undergoing IVF were stimulated in a long GnRH agonist protocol with r-FSH alone or with r-LH supplementation when the leading follicle reached diameter of 14 mm. FF was collected at the time of oocyte retrieval from 32 follicles ≥ 18 mm. Serum FSH, LH, estradiol (E(2)), and progesterone (P(4)) were evaluated on the day of hCG administration. Intra-follicular E(2), P(4), AMH and TGF-β were assayed. Total RNA from 18 individual cumuli was isolated for gene expression analyses. RESULTS R-LH increased FF P(4) levels. FF TGF-β levels and PTGS2 and HAS2 expression in cumulus cells (CCs) positively correlated with increased P(4) levels observed in FFs, while a negative correlation was found between P(4) and AMH levels. CONCLUSIONS FF positive correlation between P(4) and TGF-β levels and CC expression of PTGS2 and HAS2 suggest an association with a better follicle quality. In addition, our data suggest that late follicular phase r-LH supplementation leads to a more advanced stage of follicular maturation.

Abstract
Follicle development is controlled amongst other factors by pituitary gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH) that act in synergy in completing follicle maturation. Exogenous gonadotropins, combined with gonadotropin-releasing hormone agonists, have been successfully used in patients with ovulatory disorders undergoing assisted reproduction. There is some evidence of a beneficial role of androgens or LH administration before FSH stimulation. This study was designed to verify whether the addition of LH in the early follicular phase, in downregulated patients undergoing follicular stimulation for assisted reproduction, would add benefits in terms of general outcomes and pregnancy rates. We compared two groups of patients one of which was treated with recombinant FSH (rFSH) alone and the other with rFSH plus recombinant LH (rLH), in the early follicular phase only. The number of eggs recovered was higher in the group treated with FSH only; however, the number of embryos available at transfer was similar in the two groups and, more importantly, the number of Grades I and II embryos was higher in the group pretreated with LH. Similarly, although biochemical pregnancy rate and clinical pregnancy rates were similar in both groups, a beneficial role of LH priming was demonstrated by the higher implantation rate achieved in these patients.

Abstract
OBJECTIVE To compare highly purified human menopausal gonadotropin (HP-hMG) with recombinant follicle-stimulating hormone (rFSH) on ovarian response and pregnancy outcome in downregulated women of advanced reproductive age. DESIGN A prospective, randomized and controlled study of 127 consecutive normogonadotropic infertile women ≥ 35 years old undergoing their first in vitro fertilization/intracytoplasmic sperm injection cycles received ovarian stimulation with HP-hMG (n = 63) or with rFSH (n = 64) in a long gonadotropin-releasing hormone agonist protocol. RESULTS More leading (≥ 18 mm) follicles and oocytes were obtained in rFSH group (p = 0.008 and p < 0.001, respectively). The proportion of top-quality embryo from oocyte retrieval and live birth rate per started cycle trended towards improvement with HP-hMG (OR 1.3, 95% CI 0.9-1.8; OR 1.9, 95% CI 0.9-3.9; respectively), although they were not significant difference between two groups. At end of stimulation, higher serum progesterone level was found in rFSH group (p < 0.001). CONCLUSION Following downregulated women of advanced reproductive age, superiority of HP-hMG over rFSH in live birth rate could not be concluded from this study, but noninferiority was established. Pharmacodynamic differences in follicular development, oocyte/embryo quality and endocrine response exist between HP-hMG and rFSH, which may be relevant to treatment outcome.

Abstract
An observational, matched, case-control study was carried out to compare the efficacy of recombinant human luteinizing hormone (r-hLH) supplementation with that of urinary human menopausal gonadotrophin (u-hMG)-based LH activity during controlled ovarian stimulation (COS) for assisted reproductive technology (ART) using a long gonadotrophin-releasing hormone (GnRH)-agonist protocol. A total of 4719 women, 1573 per group, matched by age, body mass index, indication and number of previous ART cycles, were treated with either recombinant human follicle-stimulating hormone (r-hFSH) and r-hLH in a fixed 2:1 ratio or u-hMG, either alone or in combination with r-hFSH, after down-regulation in a long GnRH-agonist protocol. Compared with the two u-hMG groups (u-hMG alone or in combination with r-hFSH, respectively), r-hFSH consumption was significantly lower (p < 0.001; p < 0.001), and pregnancy rates per cycle (p = 0.006; p = 0.022) and per embryo transfer (p = 0.025; p = 0.008), and implantation rate per embryo transferred (p < 0.001; p < 0.001) were significantly higher in the group treated with the fixed combination of r-hFSH and r-hLH. In COS protocols with r-hFSH, supplementation with r-hLH appears to be more effective than supplementation with u-hMG using the long GnRH-agonist protocol for ART.

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.

Hill MJ, Levy G, Levens ED. Does exogenous LH in ovarian stimulation improve assisted reproduction success? An appraisal of the literature. Reprod Biomed Online 2011; 24:261-71. [PMID: 22285265 DOI: 10.1016/j.rbmo.2011.12.005] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2011] [Revised: 11/11/2011] [Accepted: 12/14/2011] [Indexed: 10/14/2022]
Abstract
A review of the scientific literature on the use of exogenous LH in assisted reproductive technology was performed by searching the MEDLINE, PubMed and Cochrane online databases. Scientific evidence was reviewed comparing recombinant FSH-only protocols to protocols supplemented with exogenous LH activity: human menopausal gonadotrophin (HMG), recombinant LH and mid-follicular human chorionic gonadotrophin (HCG). Studies were further compared based on pituitary suppression with gonadotrophin- releasing hormone (GnRH) antagonist and agonist protocols. Primary focus was given to randomized controlled trials and meta-analyses. Data from hypogonadotrophic hypogonadal patients demonstrated the importance of LH activity for success of assisted reproduction treatment. However, the majority of normogonadotrophic patients had adequate endogenous LH to successfully drive ovarian steroidogenesis and oocyte maturation. Exogenous LH supplementation was consistently associated with higher peak oestradiol concentrations. The use of HMG in long GnRH agonist cycles was associated with a 3–4% increase in live birth rate. There was insufficient evidence to make definitive conclusions on the need for exogenous LH activity in GnRH antagonist cycles or the benefit of recombinant LH and HCG protocols. Poor responders and patients 35 years of age and older may benefit from exogenous LH.

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 To evaluate the effect of low levels of endogenous luteinizing hormone (LH) and low-dose human chorionic gonadotropin (hCG) supplementation on in vitro fertilization (IVF) cycle outcomes in a gonadotropin-releasing hormone (GnRH) antagonist protocol. DESIGN Retrospective study. SETTING Military medical center. PATIENT(S) General in vitro fertilization/embryo transfer (IVF-ET) population. INTERVENTION(S) Addition of low-dose urinary hCG to IVF stimulations using a recombinant follicle-stimulating hormone (FSH) and GnRH antagonist protocol. MAIN OUTCOME MEASURE(S) Implantation and live-birth rates. RESULT(S) As part of a larger cohort of 239 patients, 42 patients with LH levels ≤ 0.5 mIU/mL were evaluated. In the larger cohort, there were no differences in implantation and pregnancy rates between the recombinant FSH only (n = 113) and the recombinant FSH with low-dose hCG supplementation (n = 126) groups. In the FSH-only group, patients with LH levels ≤ 0.5 mIU/mL had decreased implantation rates (19% vs. 42%) and live-birth rates (25% vs. 54%) as compared with patients with LH levels >0.5 mIU/mL. Low LH patients in the recombinant FSH with low-dose urinary hCG group had statistically significantly higher implantation rates (54% vs. 19%) and live-birth rates (64% vs. 25%) as compared with patients with similar low LH levels in the recombinant FSH-only group. CONCLUSION(S) Endogenous LH levels ≤ 0.5 mIU/mL after GnRH antagonist treatment are associated with statistically significantly lower implantation and pregnancy rates in recombinant FSH-only cycles. The addition of low-dose urinary hCG results in improved implantation and live-birth rates in patients with low LH levels.

Abstract
Objective To evaluate, retrospectively, the roles of endogenous and exogenous luteinising hormone (LH) activity on live birth rate in ovulation induction cycles. Methods Associations between LH activity at baseline, end of stimulation and live birth rate were analysed in relation to patient characteristics, baseline and end of stimulation variables in WHO group II anovulatory women (n=155) stimulated with recombinant follicle-stimulating hormone (rFSH) or highly purified human menopausal gonadotrophin (HP-hMG). HP-hMG provides FSH and exogenous LH activity mainly in the form of human chorionic gonadotrophin (hCG). Results Serum LH concentrations at baseline or end of stimulation were not predictive of live birth rate in the rFSH group (n=79) or HP-hMG group (n=76). Serum hCG concentration at end of stimulation was a significant positive predictor in HP-hMG-treated women. Other variables were not independently predictive of live birth in either of the groups, except for a negative association between serum FSH concentrations at the start of stimulation and live birth in the rFSH-treated group. Conclusions Endogenous LH concentrations are not predictive of live birth in anovulatory WHO group II patients undergoing ovulation induction with rFSH or HP-hMG. On the other hand, exogenous hCG activity during HP-hMG stimulation is positively associated with treatment outcome.

Abstract
BACKGROUND Administration of recombinant luteinizing hormone (rLH) in controlled ovarian hyperstimulation may benefit a subpopulation of patients. However, late follicular phase administration of high doses of rLH may also reduce the size of the follicular cohort and promote monofollicular development. METHODS To determine if rLH in late follicular development had a negative impact on follicular growth and oocyte yield, IVF patients in our practice who received rFSH and rLH for the entire stimulation were retrospectively compared with those that had the rLH discontinued at least two days prior to hCG trigger. RESULTS The two groups had similar baseline characteristics before stimulation with respect to age, FSH level and antral follicle count. However, the group which had the rLH discontinued at least two days prior to their hCG shot, had a significantly higher number of oocytes retrieved, including a higher number of MII oocytes and number of 2PN embryos. CONCLUSIONS When using rLH for controlled ovarian hyperstimulation, administering it from the start of stimulation and stopping it in the late follicular phase, at least two days prior to hCG trigger, may increase oocyte and embryo yield.

Abstract
BACKGROUND Women have been able to delay childbearing since effective contraception became available in the 1960s. However, fertility decreases with increasing maternal age. A slow but steady decrease in fertility is observed in women aged between 30 and 35 years, which is followed by an accelerated decline among women aged over 35 years. A combination of delayed childbearing and reduced fecundity with increasing age has resulted in an increased number and proportion of women of greater than or equal to 35 years of age seeking assisted reproductive technology (ART) treatment. METHODS Literature searches supplemented with the authors' knowledge. RESULTS Despite major advances in medical technology, there is currently no ART treatment strategy that can fully compensate for the natural decline in fertility with increasing female age. Although chronological age is the most important predictor of ovarian response to follicle-stimulating hormone, the rate of reproductive ageing and ovarian sensitivity to gonadotrophins varies considerably among individuals. Both environmental and genetic factors contribute to depletion of the ovarian oocyte pool and reduction in oocyte quality. Thus, biological and chronological ovarian age are not always equivalent. Furthermore, biological age is more important than chronological age in predicting the outcome of ART. As older patients present increasingly for ART treatment, it will become more important to critically assess prognosis, counsel appropriately and optimize treatment strategies. Several genetic markers and biomarkers (such as anti-Müllerian hormone and the antral follicle count) are emerging that can identify women with accelerated biological ovarian ageing. Potential strategies for improving ovarian response include the use of luteinizing hormone (LH) and growth hormone (GH). When endogenous LH levels are heavily suppressed by gonadotrophin-releasing hormone analogues, LH supplementation may help to optimize treatment outcomes for women with biologically older ovaries. Exogenous GH may improve oocyte development and counteract the age-related decline of oocyte quality. The effects of GH may be mediated by insulin-like growth factor-I, which works synergistically with follicle-stimulating hormone on granulosa and theca cells. CONCLUSION Patients with biologically older ovaries may benefit from a tailored approach based on individual patient characteristics. Among the most promising adjuvant therapies for improving ART outcomes in women of advanced reproductive age are the administration of exogenous LH or GH.

Abstract
The aim of this trial, comparing human follicle stimulating hormone (hFSH) and recombinant FSH (rFSH) was to evaluate the efficacy on oocyte and embryo quality in in vitro fertilisation/intracytoplasmic sperm injection cycles. Four-hundred and one women were randomised in two groups to receive or hFSH or rFSH in stimulation protocols. The primary end point of this study was the oocyte/embryo quality. No significant difference in oocyte/embryo quality was observed between the two groups. The number of oocytes retrieved was significantly higher in the hFSH group (6 +/- 2.8 in hFSH group vs. 5 +/- 2.6 in rFSH group; P = 0.003). A less amounts of gonadotropins consumed (2106 +/- 719 IU in hFSH group vs. 3536 +/- 1099 IU in rFSH group; P < 0.0001) and shorter duration of stimulation (human chorionic gonadotropin day of administration: Day 12.3 +/- 1.0 in hFSH and Day 13.3 +/- 1.2 in rFSH group, respectively; P < 0.0001) was registered in hFSH group. Fertilisation, cleavage and implantation rates, pregnancy and abortion rates were similar in both groups. However, lower clinical abortion rate (not significant) in hFSH group might be noteworthy. In our study, we demonstrated that hFSH and rFSH products are equivalent in terms of clinical efficacy.

Abstract
The objective of this study was to compare the live birth rates resulting from ovarian stimulation with highly purified human menopausal gonadotrophin (HP-HMG), which combines FSH and human chorionic gonadotrophin-driven LH activities, or recombinant FSH (rFSH) alone in women undergoing IVF cycles. An integrated analysis was performed of the raw data from two randomized controlled trials that were highly comparable in terms of eligibility criteria and post-randomization treatment regimens with either HP-HMG or rFSH for ovarian stimulation in IVF, following a long down-regulation protocol. All randomized subjects who received at least one dose of gonadotrophin in an IVF cycle (HP-HMG, n = 491; rFSH, n = 495) were included in the analysis. Subjects who underwent intracytoplasmic sperm injection cycles were excluded. The superiority of one gonadotrophin preparation over the other was tested using the likelihood ratio test in a logistic regression analysis. The live birth rate per cycle initiated was 26.5% (130/491) with HP-HMG and 20.8% (103/495) with rFSH (P = 0.041). The odds ratio in favour of HP-HMG was 1.36 (95% confidence interval: 1.01-1.83). Thus, the findings of this integrated analysis demonstrate that ovarian stimulation with HP-HMG, following a long down-regulation protocol, in IVF cycles results in significantly more live births than stimulation with rFSH alone.

Abstract
Lutropin alfa is the first and only recombinant human form of luteinizing hormone (LH) developed for use in the stimulation of follicular development. Dose-finding studies revealed a significant dose-dependent increase in the rate of optimal follicular development among women with hypogonadotropic hypogonadism and profound LH deficiency (<1.2 IU/L) who received subcutaneous lutropin alfa 0-225 IU/day plus follitropin alfa. Similarly, in a double-blind, randomized study, the rate of optimal follicular development was significantly higher in women with hypogonadotropic hypogonadism and profound LH deficiency receiving subcutaneous lutropin alfa 75 IU/day plus follitropin alfa than in those receiving placebo plus follitropin alfa. Lutropin alfa with follitropin alfa may also be of benefit in certain subgroups of normogonadotropic women (e.g. those with an inadequate response to prior follitropin alfa monotherapy, those aged >or=35 years, and those with profound LH downregulation or who required excessive exogenous follitropin alfa). However, one study in older women (>or=35 years) did not show any advantage of lutropin alfa supplementation. Once-daily subcutaneous lutropin alfa was generally well tolerated in hypogonadotropic hypogonadal women, with the majority of adverse events being of mild to moderate severity.

Abstract
PURPOSE OF REVIEW Although the key role of luteinizing hormone in ovarian function, the promotion of follicular growth and maturation, is widely acknowledged, its usefulness as a predictor of ovarian status, and as a supplement during fertility treatment, remains controversial. RECENT FINDINGS Luteinizing hormone alone is not an effective predictor of ovarian function. In combination with follicle-stimulating hormone, as the so-called follicle-stimulating hormone: luteinizing hormone ratio, it serves as a useful marker of ovarian status. Although published data on luteinizing hormone supplementation during ovarian hyperstimulation are somewhat limited, recent well-designed studies suggest a beneficial effect of: (1) luteinizing hormone supplementation for women with inadequate responses to follicle-stimulating hormone-only stimulation; (2) in primarily young patients with low baseline luteinizing hormone levels and, consequently, insufficient remaining endogenous luteinizing hormone concentration during pituitary suppression; and (3) in older women with higher baseline luteinizing hormone levels and age-appropriate ovarian function, who require higher luteinizing hormone thresholds, even during pituitary suppression. SUMMARY Luteinizing hormone levels, as a component of the follicle-stimulating hormone: luteinizing hormone ratio, contribute to the assessment of ovarian function, whereas the supplementation of luteinizing hormone on an individualized basis, in carefully selected patients, improves outcomes of ovarian stimulation with gonadotropins.

Abstract
The aim of this systematic review and meta-analysis was to assess whether the addition of recombinant luteinizing hormone (LH) increases live birth rate, among patients treated with follicle stimulating hormone (FSH) and gonadotrophin-releasing hormone (GnRH) analogues for in vitro fertilization (IVF). Eligible studies were randomized controlled trials (RCTs) answering the research question that contained sufficient information to allow ascertainment of whether randomization was true and whether equality was present between the groups compared, regarding baseline demographic characteristics, gonadotrophin stimulation protocol, number of embryos transferred and luteal phase support administered. A literature search identified seven RCTs (701 patients) that provided the information of interest, among which five reported agonist and two antagonist cycles. The reported outcome measure, clinical pregnancy, was converted to live birth using published data in one study. No significant difference in the probability of live birth was present with or without rLH addition to FSH (odds ratio [OR]: 0.92, 95% confidence interval (CI): 0.65-1.31; P = 0.65). This finding remained stable in subgroup analyses that ordered the studies by dose of rLH added, the type of analogue used to inhibit premature LH surge, the time rLH was added during the follicular phase, the age of patients analysed, the presence of allocation concealment and by the way the information on live birth was retrieved. In conclusion, the available evidence does not support the hypothesis that the addition of recombinant LH increases the live birth rate in patients treated with FSH and GnRH analogues for IVF.

Abstract
BACKGROUND During in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment cycles, controlled ovarian hyperstimulation (COH) is performed with recombinant follicle stimulating hormone (rFSH) in combination with a gonadotrophin-releasing hormone (GnRH) analogue for the prevention of premature luteinizing hormone (LH) surges. The use of GnRH analogues however deprives the growing follicles of LH. The effectiveness of co-administrating rLH to rFSH for COH is at present unclear. OBJECTIVES To compare the effectiveness and safety of a combination of recombinant LH and recombinant FSH with recombinant FSH alone in COH protocols in (IVF or ICSI followed by embryo transfer (ET). SEARCH STRATEGY We searched the MDSG Group Specialised Register (searched up to Nov 2006) and CENTRAL, MEDLINE and EMBASE (1980 to November 2006) and reference lists of articles. SELECTION CRITERIA Randomised controlled trials comparing COH with rFSH alone or in combination with rLH in IVF/ICSI were included. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trial quality and extracted data. We sought additional information if necessary. MAIN RESULTS Fourteen trials involving 2612 women were included. Eleven trials involving 2396 women used a GnRH agonist . There was no evidence of a statistical difference in live birth rate reported in two trials (OR 1.51, 95% CI 0.79 to 2.87). There was no evidence of a statistical difference in clinical pregnancy rates reported in seven trials OR 1.15, 95% CI 0.91 to 1.45. There was no evidence of a statistical difference or in ongoing pregnancy rates seven trials OR 1.22, 95% CI 0.95 to 1.56. Three trials used a GnRH antagonist. No data on live birth rates was available. There was no evidence of a statistical difference in clinical pregnancy rates (one trial: OR 0.79, 95% CI 0.26 to 2.43) or in ongoing pregnancy rates (two trials: OR 0.83, 95% CI 0.39 to 1.80) comparing both groups. The pooled pregnancy estimates of trials including only poor responders showed significant increase in pregnancy rate, in favour of co-administrating rLH (three trials: OR 1.85, 95% CI 1.10 to 3.11) AUTHORS' CONCLUSIONS There was no evidence of a statistical difference in pregnancy outcomes when rLH was used. Nevertheless, further large RCTs should be undertaken in long GnRH agonist down regulation protocols, since all pooled pregnancy estimates, although not statistically different probably due to the small numbers, point towards a beneficial effect of co-treatment with rLH, in particular with respect to pregnancy-loss and poor-responders.

Abstract
Low-dose hCG supplementation was administered at the start of ovarian stimulation, concomitantly with recombinant FSH (rFSH) in GnRH antagonist cycles, and these were compared with GnRH-a cycles that used rFSH alone. The low-dose hCG group had similar implantation and pregnancy rates but had significantly reduced rFSH requirements, allowing for an average cost savings of $600 per cycle.

Abstract
The objective of this retrospective analysis was to compare the clinical outcomes of recombinant FSH (r-FSH) with combination r-FSH plus human menopausal gonadotrophin (HMG) protocols in a large private practice using a single IVF laboratory, from 2001 to 2003. Patients underwent ovarian stimulation by standard gonadotrophin-releasing hormone (GnRH) antagonist protocol using r-FSH or combination r-FSH plus HMG. When two or more follicles had attained a minimum mean diameter of 20 mm, follicular triggering was achieved with either recombinant HCG (r-HCG; Ovidrel, 250 microg s.c.) or urinary HCG (u-HCG; 10,000 IU i.m.). The main outcome measures were number of oocytes retrieved and clinical pregnancy rate. There was a lower percentage of cancelled cycles and an increased number of oocytes retrieved, mature oocytes, oocytes that fertilized, embryo that cleaved and a tendency towards higher clinical pregnancy rates in patients treated with r-FSH alone compared with those treated with r-FSH plus HMG. Patients treated with r-FSH plus HMG had lower miscarriage rates and the live birth rate was similar in both treatment groups. In conclusion, irrespective of age, using a treatment regimen consisting of a combination of HMG plus r-FSH was not beneficial compared with r-FSH alone in patients using a GnRH antagonist protocol.

Abstract
BACKGROUND LH activity may influence treatment response and outcome in IVF cycles. METHODS A randomized, assessor-blind, multinational trial compared ongoing pregnancy rates (primary end-point) in 731 women undergoing IVF after stimulation with highly purified menotrophin (HP-hMG) (n = 363) or recombinant FSH (rFSH) (n = 368) following a long GnRH agonist protocol. Patients received identical pre- and post-randomization interventions. One or two embryos were transferred on day 3. RESULTS More oocytes were retrieved (P < 0.001) after rFSH treatment (11.8) compared with HP-hMG treatment (10.0), but a higher proportion developed into top-quality embryos (P = 0.044) with HP-hMG (11.3%) than with rFSH (9.0%). At the end of stimulation, lower estradiol (E(2)) (P = 0.031) and higher progesterone (P < 0.001) levels were found with rFSH, even after adjusting for follicular response. The distribution of hypo-, iso- and hyper-echogenic endometrium showed a significant (P = 0.023) shift towards the hyperechogenic pattern after rFSH treatment. The ongoing pregnancy rate per cycle was 27% with HP-hMG and 22% with rFSH [odds ratio (95% confidence interval): 1.25 (0.89-1.75)]. CONCLUSION Superiority of HP-hMG over rFSH in ongoing pregnancy rate could not be concluded from this study, but non-inferiority was established. Pharmacodynamic differences in follicular development, oocyte/embryo quality, endocrine response and endometrial echogenicity exist between HP-hMG and rFSH preparations, which may be relevant for treatment outcome.

Abstract
Adequate ovarian response, essential for successful IVF, cannot be accurately predicted. This study retrospectively reviewed all patients undergoing IVF from 1998 to 2001. Inclusion criteria were age <41 years at treatment onset and a basal day 3 serum FSH concentration <12 IU/l. Women with FSH <or=8 IU/l underwent a secondary analysis. Two groups emerged according to basal day 3 serum FSH/LH ratio: >or=3 in group 1 and <3 in group 2 (controls). Age at treatment initiation, basal serum day 3 FSH and LH concentrations, peak serum oestradiol concentration, number of retrieved and fertilized oocytes and pregnancy rate were analysed. Groups 1 (n = 41, 111 IVF treatment cycles) and 2 (n = 596, 1,434 IVF treatment cycles) were similar in term of woman's mean age. Group 1 had significantly higher mean basal day 3 FSH concentration (P < 0.01) and significantly lower oestradiol concentrations at oocyte retrieval (P < 0.01), mean number of oocytes retrieved and fertilized (P < 0.01) and pregnancy rate (P = 0.016). The same trend persisted after excluding 98 patients with basal FSH concentrations >8 IU/l. In conclusion, elevated day 3 FSH/LH ratio is associated with an inferior outcome in IVF treatment cycles and may be used as an additional predictor for decreased ovarian response.

Abstract
Human reproductive evolution, involving a complex interaction of the hypothalamic-pituitary-ovarian axis, the release of pulsatile and threshold concentrations of gonadotrophins and positive and negative feedback systems, has ensured the release of a single viable egg and functioning corpora lutea in the natural menstrual cycle. The use of follicular stimulation regimens to obtain multiple eggs has resulted in a compromise - in terms of the risk of ovarian hyperstimulation, cost, multiple pregnancies, wastage of or the need for cryopreservation of surplus embryos. Even some women with apparently normal menstrual cycles might become 'poor responders' when administered with follicular stimulants, and we still do not know if the incidence of oocyte aneuploidy is artificially raised after stimulation. After the advent of recombinant FSH and LH, the precise roles of these hormones individually needs to be elucidated to understand the physiological requirements for successful ovarian stimulation in each woman undergoing IVF, to maximize her chance and minimise attendant risks. One of the key debates is the role of LH, which in the natural cycle is significant, but may be redundant during ovarian stimulation for IVF. Current outcome indicators are crude when attempting to understand the physiology, and more basic research and randomized, focused clinical trials are needed.

Abstract
To allow selection of embryos for transfer after in vitro fertilization, ovarian stimulation is usually carried out with exogenous gonadotropins. To compensate for changes induced by stimulation, GnRH analog cotreatment, oral contraceptive pretreatment, late follicular phase human chorionic gonadotropin, and luteal phase progesterone supplementation are usually added. These approaches render ovarian stimulation complex and costly. The stimulation of multiple follicular development disrupts the physiology of follicular development, with consequences for the oocyte, embryo, and endometrium. In recent years, recombinant gonadotropin preparations have become available, and novel stimulation protocols with less detrimental effects have been developed. In this article, the scientific background to current approaches to ovarian stimulation for in vitro fertilization is reviewed. After a brief discussion of the relevant aspect of ovarian physiology, the development, application, and consequences of ovarian stimulation strategies are reviewed in detail.

Abstract
OBJECTIVE To evaluate the effects of recombinant human luteinizing hormone (rhLH) supplementation on ovarian stimulation and implantation rate in down-regulated women of advanced reproductive age. DESIGN Prospective randomized study. SETTING University teaching hospital. PATIENT(S) A total of 120 consecutive normogonadotropic infertile women > or = 35 years old undergoing their first cycle of IVF or intracytoplasmic sperm injection (ICSI) treatment. INTERVENTION(S) Ovarian stimulation in a long agonist protocol with a combination of recombinant human follicle-stimulating hormone (rhFSH) and rhLH (group 1, n = 60) starting on day 6 of FSH stimulation until hCG at a daily fixed dose of 150 IU of rhLH, or with rhFSH alone (group 2, n = 60). MAIN OUTCOME MEASURE(S) Ovarian stimulation characteristics, ovum retrieval, and IVF/ICSI outcome. RESULT(S) The mean number of intermediate (10-14 mm) and large (> 14- < 18 mm) but not leading (> or = 18 mm) follicles was significantly lower in group 1 on the day of hCG injection. The oocyte yield and maturity as well as the number of oocytes fertilized were significantly higher in group 2 than in group 1. However, the number of patients having embryo transfer (n = 55 in both treatment groups), the number and quality of embryos replaced, the implantation rate (20.6% vs. 21.7%) and clinical pregnancy rates per embryo transfer (44% vs. 45%) were similar in groups 1 and 2. CONCLUSION(S) The rhLH supplementation does not increase ovarian response and implantation rates in patients of older reproductive age stimulated with rhFSH under pituitary suppression for assisted reproductive technologies (ARTs).

Abstract
BACKGROUND Down-regulation with GnRH agonist has been suggested to result in a profound suppression of LH bioactivity, reduced estradiol synthesis, and thus impaired IVF and pregnancy outcome. The aims of this study were: (i) to assess the usefulness of serum LH measurement on stimulation day 1 as a predictor of ovarian response, conception and pregnancy outcome in patients treated with long-term down-regulation with GnRH agonist and recombinant FSH, and (ii) to define the best threshold LH value, if any, to discriminate between women with different outcomes of IVF. METHODS Records of 2625 cycles in 1652 infertile women undergoing IVF (n = 1856) and/or ICSI (n = 769) treatment were reviewed. RESULTS The range of LH concentrations on stimulation day 1 overlapped among non-conception cycles, conception cycles, ongoing pregnancies and early pregnancy losses. Receiver operating characteristic (ROC) analysis showed that serum LH concentrations on stimulation day 1 were unable to discriminate between conception and non-conception cycles (AUC(ROC) = 0.51; 95% CI: 0.49-0.54) or ongoing pregnancies versus early pregnancy loss groups (AUC(ROC) = 0.52; 95% CI: 0.47-0.57). Stratification for various low serum levels of LH did not reveal significant differences with respect to conception or pregnancy outcome among different LH levels on stimulation day 1. CONCLUSIONS Serum LH concentration on stimulation day 1 cannot predict ovarian response, conception and pregnancy outcome in women receiving long-term down-regulation during assisted reproduction treatment.

Abstract
The availability of recombinant FSH and LH opens an opportunity to individualize ovarian stimulation. While the need for FSH is universal, a question remains whether exogenous LH is beneficial. Previous research on adding LH to an unselected group of patients failed to demonstrate any advantage. Indeed, it may seem presumptuous to expect that all patients will respond in the same manner. Recent studies hint that LH supplementation should be individualized. These studies indirectly suggest that the changes in LH concentration may be more important than the concentration per se. The growing follicle, and particularly oestradiol biosynthesis, may be sensitive to decreases in LH concentrations. The challenge is to identify the patient whose LH will drop during stimulation. This individualized approach will assure that supplemented LH will only be given to those who need it.
