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

Abstract
OBJECTIVE To investigate whether patients with a previous recombinant follicle stimulating hormone (rFSH)-stimulated cycle would have improved outcomes with rFSH + recombinant luteinizing hormone (rLH) stimulation in the following cycle. METHODS For the present retrospective case-control study, 228 cycles performed in 114 patients undergoing intracytoplasmic sperm injection (ICSI) between 2015 and 2018 in an in vitro fertilization (IVF) center were evaluated. Controlled ovarian stimulation (COS) was achieved with rFSH (Gonal-f, Serono, Geneva, Switzerland) in the first ICSI cycle (rFSH group), and with rFSH and rLH (Pergoveris, Merck Serono S.p.A, Bari, Italy) in the second cycle (rFSH + rLH group). The ICSI outcomes were compared among the groups. RESULTS Higher estradiol levels, oocyte yield, day-3 high-quality embryos rate and implantation rate, and a lower miscarriage rate were observed in the rFSH + rLH group compared with the rFSH group. In patients < 35 years old, the implantation rate was higher in the rFSH + rLH group compared with the rFSH group. In patients ≥ 35 years old, higher estradiol levels, oocyte yield, day-3 high-quality embryos rate, and implantation rate were observed in the rFSH + rLH group. In patients with ≤ 4 retrieved oocytes, oocyte yield, mature oocytes rate, normal cleavage speed, implantation rate, and miscarriage rate were improved in the rFSH + rLH group. In patients with ≥ 5 retrieved oocytes, higher estradiol levels, oocyte yield, and implantation rate were observed in the rFSH + rLH group. CONCLUSION Ovarian stimulation with luteinizing hormone (LH) supplementation results in higher implantation rates, independent of maternal age and response to COS when compared with previous cycles stimulated with rFSH only. Improvements were also observed for ICSI outcomes and miscarriage after stratification by age and retrieved oocytes.

Recombinant luteinizing hormone supplementation in assisted reproductive technology: a review of literature. MIDDLE EAST FERTILITY SOCIETY JOURNAL 2021.

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
Studies on the role of LH supplementation in patients undergoing assisted reproductive technique use different sources of LH bioactivity-containing preparations, daily doses and modes of administration. This review aims to critically present the available evidence comparing the effect of the two commercially available LH preparations (human menopausal gonadotrophin [HMG] and recombinant FSH + recombinant LH) with different sources of intrinsic LH bioactivity (HCG versus LH, respectively) on ovarian stimulation characteristics and IVF cycle outcomes. A literature review was conducted for all relevant articles reporting on IVF and intracytoplasmic sperm injection treatment outcome after ovarian stimulation using HMG or recombinant FSH plus recombinant LH. The available studies are mostly observational, using different daily doses and modes of administration. No statistically significant differences were observed in ovarian stimulation variables and clinical pregnancy and live birth rates when HMG was compared with recombinant FSH + recombinant LH. Moreover, combined analysis of all the available prospective and retrospective studies produced no firm conclusions in favour of either source of LH bioactivity. Further large randomized controlled studies are needed to investigate the effect of the LH source on IVF outcome and to identify patients who are most likely to benefit from the addition of LH bioactivity supplementation.

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

Abstract
PURPOSE To explore serum endocrine dynamics, specifically LH levels, following rLH supplementation to rFSH following GnRH-antagonist treatment in the advance reproductive age. METHODS Women were prospectively and similarly treated employing rFSH and the flexible GnRH-antagonist protocol, while rLH was supplemented only to the study group. Serum FSH, LH, E2, and P were evaluated throughout the follicular phase. Three strategies were a priori planned to examine endocrine dynamics among women enrolled. RESULTS While serum LH drop were similar before GnRH-antagonist stimulation, it dropped more times in the control group compared to the study group. Among women receiving rFSH only, serum LH levels dropped ≤2, ≤1 and ≤0.5 mIU/mL in 71.4, 46.4, and 28.6% of cases, while this occurred only in 38.7% (P = 0.01), 6.5% (P = 0.0004) and 3.2% (P = 0.007) of women receiving combined rFSH and rLH treatment, respectively. The same trend was found when serum LH dropped in at least two occasions following the GnRH-antagonist administration. Conversely, serum LH diagrams throughout the follicular phase did not differ between the two groups. Furthermore, individual area under the curve values of LH, E2, and P was similar between the two groups following GnRH-antagonist initiation. CONCLUSIONS Different strategies to explore LH dynamics following the GnRH-antagonist administration have resulted in diverse results, implying the need for a consensus definition of LH threshold for adequate folliculogenesis and steroidogenesis. Such action would pave the way for understanding which groups of patients may benefit from rLH supplementation.

Abstract
OBJECTIVE Although the fundamental significance of both LH and FSH for adequate ovarian folliculogenesis and steroidogenesis has been extensively discussed, the clinical implication of recombinant (r) LH to rFSH for ovarian stimulation employing the GnRH antagonist protocol remains to be elucidated. The aim of this prospective randomized controlled study was to explore whether rLH supplementation to rFSH following GnRH antagonist has an added value to the late follicular ovarian steroidogenesis in the advanced reproductive aged women. DESIGN AND SUBJECTS Sixty-three consecutive infertile women above 35 years of age and/or with a previous low ovarian response admitted for IVF/ICSI treatment were prospectively randomized. Women in the study and control groups were similarly treated employing the rFSH 300 IU/day and the flexible GnRH antagonist 0·25 mg/day protocol. On the day of antagonist initiation, rLH 150 IU/day was added only to the study group and continued till the hCG day. RESULTS Serum E2 level on hCG day did not significantly differ between the study and control groups, corresponding to 1268 ± 1006 and 1113 ± 669 pg/mL, respectively (P = 0·9). In the study group, the duration of GnRH antagonist administration was significantly lower than the control group corresponding to 5·0 ± 1·5 to 4·0 ± 1·5 days, respectively (P < 0·05). The total dosage of rFSH administration did not differ between the two groups. CONCLUSIONS rLH supplementation to rFSH following GnRH antagonist administration employing the flexible protocol does not seem to significantly augment serum E2 level on the day of hCG administration in the advanced reproductive ageing women. This suggests that endogenous serum LH levels following GnRH antagonist initiation are sufficient for adequate late follicular ovarian steroidogenesis in this setting.

Abstract
INTRODUCTION The results of a recent meta-analysis showed that adding recombinant human luteinising hormone (r-hLH) to recombinant human follicle-stimulating hormone (r-hFSH) for ovarian stimulation was beneficial in poor responders, resulting in a 30% relative increase in the clinical pregnancy rate compared with r-hFSH monotherapy. However, a limitation of the meta-analysis was that the included studies used heterogeneous definitions of poor ovarian response (POR). Furthermore, the use of r-hLH supplementation during ovarian stimulation is a topic of ongoing debate, and well-designed, adequately powered, multicentre, randomised controlled trials in this setting are warranted. Therefore, the objective of the ESPART trial is to explore the possible superiority of a fixed-dose combination of r-hFSH plus r-hLH over r-hFSH monotherapy in patients with POR, as per a definition aligned with the European Society of Human Reproduction and Embryology (ESHRE) Bologna criteria. METHODS AND ANALYSIS Phase III, randomised, single-blind, parallel-group trial in women undergoing in vitro fertilisation and/or intracytoplasmic sperm injection. Approximately 946 women aged 18-<41 years from 18 countries will be randomised (1:1) to receive a fixed-dose combination of r-hFSH plus r-hLH in a 2:1 ratio (Pergoveris) or r-hFSH monotherapy (GONAL-f). The primary end point is the total number of retrieved oocytes per participant. Secondary end points include: ongoing pregnancy rate, live birth rate, implantation rate, biochemical pregnancy rate and clinical pregnancy rate. Safety end points include: incidence and severity of ovarian hyperstimulation syndrome, and of adverse events and serious adverse events. ETHICS AND DISSEMINATION The study will be performed in accordance with ethical principles that have their origin in the Declaration of Helsinki, with the International Conference on Harmonisation-Good Clinical Practice guidelines and all applicable regulatory requirements. All participants will provide written informed consent prior to entry. The results of this study will be publically disseminated. TRIAL REGISTRATION NUMBERS ClinicalTrials.gov identifier: NCT02047227; EudraCT Number: 2013-003817-16; Clinical Trial Protocol Number: EMR200061-005 V.3.0, 15 April 2014.

Abstract
Assisted reproduction technologies require ovarian stimulation to increase the number of oocytes and embryos. Currently, superstimulation is achieved by gonadotropin treatment, but the embryo yield and quality are highly variable. Commonly, commercial preparations derived from pituitary and urinary origin are used to superovulate. Hence, ovarian superstimulation protocols have usually included both FSH and LH. The appearance of recombinant gonadotropins manufactured by genetic engineering techniques has ensured high quality and batch-to-batch consistency. Moreover, this enables us to assess the importance of LH in the ovarian stimulation. The main aim of this study was to evaluate the effect of recombinant human LH supplementation (10%) on embryonic development produced by rabbit does superovulated with low or high concentration (18.75 or 37.50 IU) of recombinant human FSH (rhFSH). Females treated with rhFSH increased the ovulation rate, and it was significantly higher when the high FSH dose was supplemented with LH. The superstimulation treatment used did not significantly affect in vitro development rate until the expanded blastocyst stage. The results of this study seem to suggest that, in terms of superovulatory response, when rabbit does are treated with 37.5-IU rhFSH, the use of LH supplementation allows an increase in the number of follicles recruited and the quality of embryos, in terms of ability to develop in vitro until blastocyst, and the expression profile of OCT4, NANOG, and SOX2 genes is not affected.

Reprod Biol Endocrinol 2014; 12:17.

Abstract
BACKGROUND The potential benefit of adding recombinant human luteinizing hormone (r-hLH) to recombinant human follicle-stimulating hormone (r-hFSH) during ovarian stimulation is a subject of debate, although there is evidence that it may benefit certain subpopulations, e.g. poor responders. METHODS A systematic review and a meta-analysis were performed. Three databases (MEDLINE, Embase and CENTRAL) were searched (from 1990 to 2011). Prospective, parallel-, comparative-group randomized controlled trials (RCTs) in women aged 18-45 years undergoing in vitro fertilization, intracytoplasmic sperm injection or both, treated with gonadotrophin-releasing hormone analogues and r-hFSH plus r-hLH or r-hFSH alone were included. The co-primary endpoints were number of oocytes retrieved and clinical pregnancy rate. Analyses were conducted for the overall population and for prospectively identified patient subgroups, including patients with poor ovarian response (POR). RESULTS In total, 40 RCTs (6443 patients) were included in the analysis. Data on the number of oocytes retrieved were reported in 41 studies and imputed in two studies. Therefore, data were available from 43 studies (r-hFSH plus r-hLH, n=3113; r-hFSH, n=3228) in the intention-to-treat (ITT) population (all randomly allocated patients, including imputed data). Overall, no significant difference in the number of oocytes retrieved was found between the r-hFSH plus r-hLH and r-hFSH groups (weighted mean difference -0.03; 95% confidence interval [CI] -0.41 to 0.34). However, in poor responders, significantly more oocytes were retrieved with r-hFSH plus r-hLH versus r-hFSH alone (n=1077; weighted mean difference +0.75 oocytes; 95% CI 0.14-1.36). Significantly higher clinical pregnancy rates were observed with r-hFSH plus r-hLH versus r-hFSH alone in the overall population analysed in this review (risk ratio [RR] 1.09; 95% CI 1.01-1.18) and in poor responders (n=1179; RR 1.30; 95% CI 1.01-1.67; ITT population); the observed difference was more pronounced in poor responders. CONCLUSIONS These data suggest that there is a relative increase in the clinical pregnancy rates of 9% in the overall population and 30% in poor responders. In conclusion, this meta-analysis suggests that the addition of r-hLH to r-hFSH may be beneficial for women with POR.

Abstract
BACKGROUND Based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) put on their main effects on the granulosa and theca cells. LH is essential for androgens production. Androgens are used for estradiol production by granulosa cells. Profound suppression of LH concentrations in some normogonadotropic patients can cause several adverse effects. OBJECTIVE The main clinical purpose of this study was that normoresponder women treated with controlled ovarian super ovulation for IVF or ICSI may benefit from co-administration of rLH. MATERIALS AND METHODS 40 patients who were candidates for assisted reproductive technology (ART) were randomly selected. In all patients long luteal protocol was used for ovulation induction. Patients were randomly divided into two groups: Group 1 (n=20) with standard long protocol (GnRH agonist) and r-FSH alone, Group 2 (n=20) with standard long protocol (GnRH agonist) and r-FSH with r-LH. RESULTS were statistically analyzed and compared in two groups. RESULTS The number of retrieved oocytes, mature oocytes, cleaved embryos, transferred embryos, estradiol levels in Human chorionic gonadotropin (hCG) administration day, implantation rate and clinical pregnancy rate in group 2 were higher but not significantly different. CONCLUSION Administration of rLH in late follicular phase had no beneficial effect on outcomes in young women with mean age of 31 years. Maybe a greater sample size should be used to see the effects more accurately; also it is possible that rLH will be useful in older patients. Registration ID in IRCT: IRCT201304302575N4.

Abstract
Gonadotropin therapy plays an integral role in ovarian stimulation for infertility treatments. Efforts have been made over the last century to improve gonadotropin preparations. Undoubtedly, current gonadotropins have better quality and safety profiles as well as clinical efficacy than earlier ones. A major achievement has been introducing recombinant technology in the manufacturing processes for follicle-stimulating hormone, luteinizing hormone, and human chorionic gonadotropin. Recombinant gonadotropins are purer than urine-derived gonadotropins, and incorporating vial filling by mass virtually eliminated batch-to-batch variations and enabled accurate dosing. Recombinant and fill-by-mass technologies have been the driving forces for launching of prefilled pen devices for more patient-friendly ovarian stimulation. The most recent developments include the fixed combination of follitropin alfa + lutropin alfa, long-acting FSH gonadotropin, and a new family of prefilled pen injector devices for administration of recombinant gonadotropins. The next step would be the production of orally bioactive molecules with selective follicle-stimulating hormone and luteinizing hormone activity.

A comparison of outcomes from in vitro fertilization cycles stimulated with either recombinant luteinizing hormone (LH) or human chorionic gonadotropin acting as an LH analogue delivered as human menopausal gonadotropins, in subjects with good or poor ovarian reserve: a retrospective analysis. Eur J Obstet Gynecol Reprod Biol 2013; 172:70-3. [PMID: 24314801 DOI: 10.1016/j.ejogrb.2013.10.027] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2012] [Revised: 10/10/2013] [Accepted: 10/27/2013] [Indexed: 11/30/2022]
Abstract
OBJECTIVES To compare rates of pregnancy and IVF parameters in subjects who were stimulated with FSH plus recombinant human luteinizing hormone or menopausal gonadotropins. To determine whether responses to type of LH differ in poor or good responders. STUDY DESIGN Retrospective analysis at a university-based fertility center. Subjects were women with good and poor ovarian reserve, who underwent in vitro fertilization during a 2 year period, as part of a long agonist (N=122), or microdose flair (N=79) protocol. Measurements included FSH and LH dose, number of oocytes collected, number of embryos obtained, and pregnancy and clinical pregnancy rates. RESULTS Patients treated with r-hLH (n=105) had higher numbers of eggs retrieved and of embryos while using less FSH than their hMG-treated (n=96) counterparts. Pregnancy and clinical pregnancy rates were significantly higher with r-hLH than with hMG protocols (p=0.008 and 0.009, respectively). If patients had a baseline serum FSH level ≥10IU/L, clinical pregnancy rates were higher when r-hLH was used. When the antral follicle count was below 6 no significant differences in stimulation parameters or outcomes were detected between the groups. CONCLUSION r-hLH may be beneficial when compared to hMG and used for in-vitro fertilization, except in subjects with baseline follicle counts less than 6. Further data should be obtained.

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
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
OBJECTIVE To determine the efficacy of the flare-up agonist and the antagonist protocols in patients with poor prognosis for ovarian response. METHODS A randomised trial was conducted on two hundred and twenty-one women considered as having poor prognosis for ovarian response to stimulation, based on previous cycles or clinical criteria. All women were prospectively randomised into two groups of treatment (flare-up group and antagonist group) by computer-assisted randomisation in a 1:1 ratio. The main outcome measure was clinical pregnancy rate. RESULTS Groups were homogeneous in age and baseline characteristics. Duration of stimulation, gonadotropin consumption, number of oocytes retrieved and number and quality of embryos transferred did not differ significantly between the groups. E(2) level the day of hCG administration was significantly higher in the flare-up group. Pregnancy rates per started cycle were 15% in the flare-up group and 14.1% in the antagonist group. Cancellation rates were 12.5% in the flare-up group and 16.3% in the antagonist group. None of these differences reached statistical significance. CONCLUSIONS No statistically significant differences were observed between the two protocols regarding clinical pregnancy rates. In patients with poor prognosis for ovarian response, the flare-up agonist and the antagonist protocols were comparable regarding clinical pregnancy rates.

Abstract
Recombinant human follicle stimulating hormone (rFSH) and luteinizing hormone (LH), also known as follitropin alpha and lutropin alpha, are manufactured by genetic engineering techniques which ensure high quality and batch to batch consistency. Follitropin alpha can be used for controlled ovarian hyperstimulation in assisted reproduction, ovulation induction for WHO group I and II anovulatory infertility and in men with hypogonadotrophic hypogonadism (HH) or idiopathic oligo-asthenospermia. Current evidence suggests superiority of urinary human menopausal gonadotropin (HMG) over follitropin alpha in controlled ovarian hyperstimulation for IVF in terms of live birth rate per couple. Addition of lutropin to follitropin alpha in an unselected IVF population does not appear to confer any benefit; however, it may have a role in ovulation induction in women with hypothalamic hypogonadism. Urinary HMG preparations (especially currently available highly purified preparations) are more cost effective than rFSH in terms of cost per ongoing pregnancy. However, women using rFSH injection pen devices have higher levels of satisfaction as compared to those using urinary HMG by means of conventional syringes.

Abstract
Second cycle outcomes of 75 patients who had previous inadequate ovarian response with recombinant FSH (rFSH)-only ovarian stimulation during gonadotrophin-releasing hormone analogue (GnRHa) down-regulated cycles were evaluated retrospectively. In these second cycles, both rFSH and human menopausal gonadotrophin (HMG) in GnRHa long down-regulation were given to all patients, HMG initiated either on day 1 (group A, n=37) or day 5-6 of the ovarian stimulation (group B, n=38). Total HMG dose was higher (1198+/-514 IU versus 726+/-469 IU; P<0.001), cumulative rFSH consumption was lower (1823+/-804 IU versus 2863+/-1393 IU; P=0.001) and duration of stimulation was shorter (8.94+/-1.15 days versus 10.37+/-1.80 days; P<0.001) in group A than in group B. No significant differences were found regarding fertilization, implantation or pregnancy rates and embryo quality between the groups. Further analysis by supplementary HMG dose (75 IU versus 150 IU) revealed that total gonadotrophin and HMG consumption was lower in 75 IU-supplemented subgroups. Notably, pregnancy rate was higher in patients where 75 IU HMG was supplemented on day 5-6 of ovarian stimulation, which deserves further evaluation.

Abstract
BACKGROUND Some studies have suggested that the suppression of endogenous LH secretion does not seem to affect the majority of patients who are undergoing assisted reproduction and stimulation with recombinant FSH (r-FSH). Other studies have indicated that a group of normogonadotrophic women down-regulated and stimulated with pure FSH preparations may experience low LH concentrations that compromise the IVF parameters. The present study aimed to compare the efficacy of recombinant LH (r-LH) supplementation for controlled ovarian stimulation in r-FSH and GnRH-agonist (GnRH-a) protocol in ICSI cycles. METHODS A total of 244 patients without ovulatory dysfunction, aged <40 years and at the first ICSI cycle were divided into two groups matched by age according to an ovarian stimulation scheme: Group I (n = 122): Down-regulation with GnRH-a + r-FSH and Group II (n = 122): Down-regulation with GnRH-a + r-FSH and r-LH (beginning simultaneously). RESULT(S) The number of oocytes collected, the number of oocytes in metaphase II and fertilization rate were significantly lower in the Group I than in Group II (P = 0.036, P = 0.0014 and P = 0.017, respectively). In addition, the mean number of embryos produced per cycle and the mean number of frozen embryos per cycle were statistically lower (P = 0.0092 and P = 0.0008, respectively) in Group I than in Group II. Finally the cumulative implantation rate (fresh+thaw ed embryos) was significantly lower (P = 0.04) in Group I than in Group II. The other clinical and laboratory results analyzed did not show difference between groups. CONCLUSION These data support r-LH supplementation in ovarian stimulation protocols with r-FSH and GnRH-a for assisted reproduction treatment.
