RESUMEN
Objective: Both pulsatile gonadotropin-releasing hormone (GnRH) and combined gonadotropin therapy are effective to induce spermatogenesis in men with congenital hypogonadotropic hypogonadism (CHH). This study aimed to evaluate the effect of pulsatile GnRH therapy on spermatogenesis in male patients with CHH who had poor response to combined gonadotropin therapy. Materials and methods: Patients who had poor response to combined gonadotropin therapy ≥ 6 months were recruited and shifted to pulsatile GnRH therapy. The rate of successful spermatogenesis, the median time to achieve spermatogenesis, serum gonadotropins, testosterone, and testicular volume were used for data analysis. Results: A total of 28 CHH patients who had poor response to combined gonadotropin (HCG/HMG) therapy for 12.5 (6.0, 17.75) months were recruited and switched to pulsatile GnRH therapy for 10.0 (7.25, 16.0) months. Sperm was detected in 17/28 patients (60.7%). The mean time for the appearance of sperm in semen was 12.0 (7.5, 17.5) months. Compared to those who could not achieve spermatogenesis during pulsatile GnRH therapy, the successful group had a higher level of LH60min (4.32 vs. 1.10 IU/L, P = 0.043) and FSH60min (4.28 vs. 1.90 IU/L, P = 0.021). Testicular size increased during pulsatile GnRH therapy, compared to previous HCG/ HMG therapy (P < 0.05). Conclusion: For CHH patients with prior poor response to one year of HCG/ HMG therapy, switching to pulsatile GnRH therapy may induce spermatogenesis.

OBJECTIVE: To compare the effects of combined gonadotropin and pulsatile gonadotropin-releasing hormone (GnRH) therapy on spermatogenesis in patients with pituitary stalk interruption syndrome (PSIS). METHODS: Male patients with PSIS (N = 119) were retrospectively studied. Patients received pulsatile GnRH therapy (N = 59) were divided into response and poor-response groups based on luteinizing hormone (LH) levels after 1-month treatment with a cutoff value of 1 or 2 IU/L. Participants with gonadotropin therapy were divided into human menopausal gonadotropin (hMG)/human chorionic gonadotropin (hCG) group (N = 60), and patients with pulsatile GnRH therapy were classified into GnRH group (N = 28) with treatment duration ≥6 months. RESULTS: The overall success rates of spermatogenesis for hMG/hCG and GnRH therapy were 51.67% (31/60) vs 33.90% (20/59), respectively. GnRH group required a shorter period to induce spermatogenesis (8 vs 15 months, P = .019). hMG/hCG group had higher median total testosterone than GnRH group [2.16, interquartile range(IQR) 1.06-4.89 vs 1.31, IQR 0.21-2.26 ng/mL, P = .004]. GnRH therapy had a beneficial effect on spermatogenesis compared to hMG/hCG therapy (hazard ratio 1.97, 95% confidence interval 1.08-3.57, P = .026). In patients with pulsatile GnRH therapy, compared with the poor-response group, the response group had a higher successful spermatogenesis rate (5.00% vs 48.72%, P = .002) and higher median basal total testosterone (0.00, IQR 0.00-0.03 vs 0.04, IQR 0.00-0.16 ng/mL, P = .026) with LH = 1 IU/L as the cutoff value after 1-month pulsatile GnRH therapy. CONCLUSIONS: Pulsatile GnRH therapy was superior to hMG/hCG therapy for spermatogenesis in patients with PSIS. Earlier spermatogenesis and higher concentrations of sperm could be obtained in the GnRH group if patients received therapy over 6 months.

PURPOSE: We have previously published a retrospective matched-case control study comparing the effect of recombinant LH (r-hLH) versus highly purified human menopausal gonadotropin (hMG) supplementation on the follicle-stimulating hormone (FSH) during controlled ovarian hyperstimulation (COH) in the GnRH-antagonist protocol. The result from that study showed that the cumulative live birth rate (CLBR) was significantly higher in the r-hLH group (53% vs. 64%, p = 0.02). In this study, we aim to do a cost analysis between these two groups based on our previous study. METHODS: The analysis consisted of 425 IVF and ICSI cycles in our previous study. There were 259 cycles in the r-hFSH + hMG group and 166 cycles in the r-hFSH + r-hLH group. The total cost related to the treatment of each patient was recorded. Probabilistic sensitivity analysis (PSA) and a cost-effectiveness acceptability curve (CEAC) were performed and created. RESULTS: The total treatment cost per patient was significantly higher in the r-hFSH + r-hLH group than in the r-hFSH + hMG group ($4550 ± 798.86 vs. $4290 ± 734.6, p = 0.003). However, the mean cost per live birth in the r-hFSH + hMG group was higher at $8052, vs. $7059 in the r-hFSH + r-hLH group. The CEAC showed that treatment with hFSH + r-hLH proved to be more cost-effective than treatment with r-hFSH + hMG. Willingness-to-pay was evident when considering a hypothetical threshold of $18,513, with the r-hFSH + r-hLH group exhibiting a 99% probability of being considered cost-effective. CONCLUSION: The cost analysis showed that recombinant LH is more cost-effective than hMG supplementation on r-hFSH during COH in the GnRH-antagonist protocol.

The purpose of this research was to evaluate the efficacy of 3 ovulation induction therapies for treating infertility in patients with polycystic ovary syndrome (PCOS). In this retrospective study, we compared the success rates of 90 patients who underwent intrauterine insemination, who were randomly assigned to 1 of 3 treatment groups: letrozole (LE) + urinary gonadotropin (human menopausal gonadotropin [HMG]), clomiphene (CC) + HMG, or HMG alone. Using ultrasound scanning, we examined the number of mature follicles, ovulation rate, clinical pregnancy rate, endometrial thickness, and blood flow. When compared to the other 2 groups, the LE + HMG group had significantly higher levels of mature follicles, ovulation rate, clinical pregnancy rate, estradiol, and luteinizing hormone on the day of the human chorionic gonadotropin injection and endometrial receptivity (P < .05). There was no statistically significant difference between the 3 groups in terms of abortion rate, ectopic pregnancy rate, or adverse reactions. In this research, we found that infertility in patients with PCOS could be effectively treated by combining LE with HMG. This protocol increased ovulation, boosted fertility, and enhanced endometrial receptivity with no increase in adverse reactions. Therefore, it may be a useful clinical approach for inducing ovulation and treating infertility in patients with PCOS.

OBJECTIVES: The aim of the study was to evaluate dosing of recombinant human luteinizing hormone (r-hLH) or human menopausal gonadotrophin (hMG)-derived medications with LH activity in ovarian stimulation (OS) cycles for in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). DESIGN: A non-interventional study was performed to analyse data from the German RecDate database (January 2007-December 2011). PARTICIPANTS/MATERIALS, SETTING, METHODS: Starting/total r-hLH/hMG dose, OS duration/cycle number, r-hLH/hMG initiation day (first day of administration), and population/cycle characteristics were assessed in women (≥18 years) undergoing OS for IVF/ICSI using r-hLH or hMG-derived medications (excluding corifollitropin alfa, clomiphene citrate, letrozole, mini/micro-dose human chorionic gonadotrophin, and urofollitropin alone). Data were summarized descriptively. RESULTS: 67,858 identified cycles utilized medications containing r-hLH (10,749), hMG (56,432), or both (677). Mean (standard deviation) OS duration with r-hLH and hMG was 10.1 (4.43) and 9.8 (6.16) days, respectively. Median (25th-75th percentile) r-hLH starting dose (75.0 [75.0-150.0] IU) was consistent across patients regardless of age, infertility diagnosis, or gonadotrophin-releasing hormone (GnRH) protocol. Median (25th-75th percentile) hMG-derived LH activity starting dose was 225.0 (150.0-300.0) IU, regardless of GnRH protocol, but was lower in women aged <35 years and those with ovulation disorders/polycystic ovary syndrome. Median (25th-75th percentile) total dose for r-hLH (750.0 [337.5-1,125.0] IU) and hMG-derived LH activity (1,575.0 [750.0-2,625.0] IU) varied according to patients' age, infertility diagnosis, cycle number, and r-hLH/hMG initiation day. GnRH antagonist use resulted in a numerically higher median total hMG-derived LH activity dose than GnRH agonist use. LIMITATIONS: The data used in this study were taken from electronic medical records relating to a specific timeframe (2007-2011) and therefore may not accurately reflect current clinical practice; however, it is likely that the differences between the two compounds would be maintained. Additionally, secondary data sources may suffer from uniformity and quality issues. CONCLUSIONS: The standard of care for OS cycles is described with respect to IVF/ICSI treatment including an LH component in Germany during the specified timeframe.

PURPOSE: An impact of different gonadotrophins selection for ovarian stimulation (OS) on oocyte competence has yet to be defined. In this study, we asked whether an association exists between OS protocol and euploid blastocyst rate (EBR) per metaphase-II (MII) oocytes. METHODS: Cycles of first preimplantation genetic testing for aneuploidies conducted by women ≥ 35 years old with their own metaphase-II oocytes inseminated in the absence of severe male factor (years 2014-2018) were clustered based on whether recombinant FSH (rec-FSH) or human menopausal gonadotrophin (HMG) was used for OS, then matched for the number of fresh inseminated eggs. Four groups were outlined: rec-FSH (N = 57), rec-FSH plus rec-LH (N = 55), rec-FSH plus HMG (N = 112), and HMG-only (N = 127). Intracytoplasmic sperm injection, continuous blastocyst culture, comprehensive chromosome testing to assess full-chromosome non-mosaic aneuploidies and vitrified-warmed euploid single embryo transfers (SETs) were performed. The primary outcome was the EBR per cohort of MII oocytes. The secondary outcome was the live birth rate (LBR) per first SETs. RESULTS: Rec-FSH protocol was shorter and characterized by lower total gonadotrophin (Gn) dose. The linear regression model adjusted for maternal age showed no association between the Gn adopted for OS and EBR per cohort of MII oocytes. Similarly, no association was reported with the LBR per first SETs, even when adjusting for blastocyst quality and day of full blastulation. CONCLUSION: In view of enhanced personalization in OS, clinicians shall focus on different endpoints or quantitative effects related to Gn action towards follicle recruitment, development, and atresia. Here, LH and/or hCG was administered exclusively to women with expected sub/poor response; therefore, we cannot exclude that specific Gn formulations may impact patient prognosis in other populations.

RESEARCH QUESTION: Is sequential letrozole/human menopausal gonadotrophin (HMG) superior to letrozole alone in ovulation induction and pregnancy promotion among infertile women with polycystic ovary syndrome (PCOS)? DESIGN: This open-label randomized controlled trial comparing sequential letrozole/HMG and letrozole alone included 174 participants enrolled from August 2019 to January 2020 at the Union Hospital of Tongji Medical College, Huazhong University of Science and Technology. Infertile women aged between 18 and 40 years who met Rotterdam criteria for PCOS and without other known causes of infertility were selected for this study. Patients were randomly assigned at a 1:1 ratio to receive 2.5 mg letrozole on cycle days 3-7 (nâ¯=â¯87) or 2.5 mg letrozole on cycle days 3-7 with a sequential injection of 75 IU HMG on cycle days 8-10 for one treatment cycle (nâ¯=â¯87). The pregnancy outcome was recorded after one treatment cycle. RESULTS: Women receiving sequential treatment achieved a significantly higher ovulation rate than those in the letrozole group (90.8% versus 70.1%, Pâ¯=â¯0.001) and the live birth rate of the sequential group was significantly higher than that of the letrozole protocol (23.0% versus 10.3%, Pâ¯=â¯0.025); there was no statistical variation with respect to adverse events. CONCLUSIONS: The data suggest that the sequential letrozole/HMG protocol may be superior to the letrozole alone protocol in terms of ovulation induction and pregnancy promotion among infertile women with PCOS.

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a main cause of anovulatory infertility in women of reproductive age. About 30% to 50% of patients with PCOS has high serum basal luteinizing hormone (LH) levels, and almost 5% of PCOS women with high LH have poor ovarian response (POR). We reported a case of a PCOS woman with high basal LH levels who canceled due to POR during two consecutive controlled ovarian stimulation treatments, which was considered to be related to the suppression of LH levels during downregulation. Clomiphene citrate (CC) combined with human menopausal urinary gonadotropin (HMG) mild regimen did not affect LH levels and obtained good follicular development, providing a new treatment insight for patients with PCOS combined with POR. PATIENT CONCERNS: A 28-year-old PCOS woman with high basal LH levels, underwent IVF assisted pregnancy treatment in our hospital, whom canceled due to POR during two traditional controlled ovulation induction program. Follicular development was finally achieved with CC milder protocol. DIAGNOSIS: This patient with the diagnosis of PCOS was undergone IVF assisted pregnancy treatment in our hospital. INTERVENTIONS: CC protocol supports the development of follicular. OUTCOMES: CC protocol resulted in better follicular development and high-quality embryos due to the continuous maintenance of an elevated LH levels. CONCLUSION: PCOS women with poor ovarian response required relatively higher LH to maintain the normal development of follicles.

Research question: What does the evolution of serum luteinizing hormone (LH) levels look like throughout the follicular phase of cycles in which gonadotrophins and gonadotropin-releasing hormone (GnRH) analogues in the context of ovarian stimulation for assisted reproduction technologies (ART) were used?Design: This was a retrospective, observational cohort study in a tertiary infertility clinic. 1303 patients aged between 18 and 43 years of age were included with a total of 2200 cycles for ART, using GnRH-analogues for pituitary down-regulation stimulated with human menopausal gonadotropin (hMG) or recombinant follicle stimulating hormone (rec-FSH). Follicular evolution of LH during ovarian stimulation in different treatment protocols was modeled as repeated measures.Results: LH evolution showed a significant decrease in antagonist/hMG cycles of 0.17 IU/L per day (95% CI [-0.20, -0.12]) and 0.26 IU/L per day in rec-FSH cycles (95% CI [-0.29, -0.22]). This decrease was significantly stronger in rec-FSH cycles than in hMG cycles (estimated difference of 0.09 IU/L per day, 95% CI [0.04, 0.15]). Short agonist/hMG cycles showed a significant increase in LH of 0.04 IU/L per day (95% CI [0.01, 0.08]), while the increase of 0.01 IU/L per day in cycles with rec-FSH was not significant (95% CI [-0.08, 0.10]).Conclusion: Follicular evolution of LH during controlled ovarian stimulation differs between different GnRH analogue cycles. A statistically significant decrease in LH was shown in GnRH antagonist cycles being more pronounced with rec-FSH compared to hMG. This decrease in LH in antagonist cycles and the potential impact on estradiol levels and follicle growth needs further examination.

Aims: To ask lots of questions and try to find the truth about the medicine-based effectiveness of letrozole (LE) combined with human menopausal gonadotropin (HMG) in the treatment of inability to have children crops patients with endocrine (things that are different from what is usually expected and the effect on ovulation-related chemicals produced by the body). Materials and Methods: A total of 160 unable to have children crops patients with endocrine things that are different from what is usually expected who were treated in our hospital from March 2019 to March 2022 were selected as the subjects of this look at how things were in the past study and were divided into instance of watching, making a statement group was treated with human menopausal gonadotropin on the basis of the control group. The differences in serum related to the process of making children, chemical produced by the body levels, ovarian function, and ovulation induction effect between the two groups were watched and compared. Results: After treatment, LH, FSH, PRL, and E2 in the observation group were better than those in the control group. The ovarian volume, follicle size, follicle diameter, and endometrial thickness of the two groups of patients were significantly improved, and the observation group was better than the control group. Significance is P < 0.05. After treatment, the ovarian volume, follicle size, follicle diameter, and endometrial thickness in the two groups were significantly improved, and the observation group was better than the control group, and the difference was statistically significant (P < 0.05). The ovulation rate, pregnancy rate, singleton pregnancy rate, and multiple pregnancy rate of the observation group were higher than those of the control group, and the difference was statistically significant by the chi-square test (P < 0.05). Conclusion: Letrozole can promote the improvement of sex hormones in infertile patients. After being combined with human menopausal gonadotropin treatment, the follicle development and ovulation of patients are significantly improved, and infertility is improved to a certain extent. It has a certain reference value in the clinical treatment of endocrine abnormal infertility.

Background: To date, no consensus has been reached on whether to wait for spontaneous luteinizing hormone (LH) surge to occur or to trigger ovulation regardless of the presence of an LH surge for achieving higher success rate in intrauterine insemination (IUI) cycles. Therefore, we hope to investigate the effect of the presence of a spontaneous LH surge on pregnancy outcomes in letrozole-human menopausal gonadotropin (LE-HMG) IUI cycles. Methods: In this retrospective cohort study, a total of 6,285 LE-HMG IUI cycles were included between January 2010 and May 2021. Cycles were categorized into three groups: the trigger + LH surge group, the trigger only group, and the LH surge only group. The primary outcome measure was the clinical pregnancy rate. A logistic regression analysis was performed to explore other risk factors affecting the clinical pregnancy rate. Results: No significant differences were observed in biochemical pregnancy rate (P =0.640), clinical pregnancy rate (P =0.702), ongoing pregnancy rate (P =0.842), and live birth rate (P =0.951) among the three groups. The binary logistic regression analysis also confirmed that the existence of an LH surge was not associated with clinical pregnancy. There was a difference in ectopic pregnancy rates (P =0.045), but logistic regression showed that the presence of a spontaneous LH surge has no association with ectopic pregnancy. Nonetheless, patients with lead follicles within 18.1-20.0 mm/20.1-22.0 mm and a long duration of LE treatment were less likely to get ectopic pregnant compared with patients with 14.1-16.0 mm lead follicles and shorter LE treatment (OR: 0.142, 95% CI: 0.023-0.891, P =0.037; OR: 0.142, 95% CI: 0.022-0.903, P =0.039; OR: 0.445, 95% CI: 0.235-0.840, P = 0.013). Conclusions: The presence of a spontaneous LH surge in triggered LE-HMG IUI cycles does not appear to improve pregnancy rates. Thus, we suggest that waiting for an LH surge to occur is not necessary in triggered LE-HMG IUI cycles.

This was a retrospective real-world evidence analysis of the costs per live birth for reference recombinant human follicle-stimulating hormone alfa (r-hFSH-alfa) versus highly purified urinary human menopausal gonadotropin (hMG-HP), based on data from a German in vitro fertilization registry (RecDate). Pregnancy and live birth rates from the RecDate real-world evidence study over three complete assisted reproductive technology (ART) cycles using the same gonadotropin drug were used as clinical inputs. Costs related to ART treatment and to drugs were obtained from public sources. Treatment with r-hFSH-alfa resulted in higher adjusted cumulative live birth rates versus hMG-HP after one (25.3% vs. 22.3%), two (30.9% vs. 27.5%), and three (31.9% vs. 28.6%) ART cycles. Costs per live birth were lower with r-hFSH-alfa versus hMG-HP after one (17,938 vs. 20,054), two (18,251 vs. 20,437), and three (18,473 vs. 20,680) ART cycles. r-hFSH-alfa was found to be a cost-effective strategy compared with hMG-HP over three cycles.

Objective: To compare the effects of human menopausal gonadotropin (HMG) combined with letrozole (LE) to HMG only for ovarian stimulation on pregnancy outcome of infertile patients undergoing artificial insemination by husband (AIH) due to unexplained or mild male factors. Materials and methods: Infertile patients with unexplained or mild male factors treated from July 2015 to December 2021 were selected as subjects. The patients were divided into two groups according to the ovarian stimulation schemes they received, namely HMG combined with LE or HMG only. We analyzed the laboratory examination results before drug treatment (baseline) and during ovarian stimulation and compared the pregnancy outcomes of the two groups using univariable analysis and multivariable logistic regression analysis. Results: In total, 526 cycles of 372 couples were included. The univariate analysis showed that the clinical pregnancy rate of the HMG combined with LE group was 24.8%, significantly higher than that of the HMG group (14.8%, P = 0.007). The live birth rate (19.9%) of the HMG combined with LE group were also significantly higher than those of the HMG group (11.2%, respectively). In multivariate logistic analysis, the age of males was negatively associated with the clinical pregnancy rate (OR 0.874, 95% CI 0.793~0.963, P=0.006) and live birth (OR0.875, 95% CI 0.783~0.977, P=0.018). Moreover, ovarian stimulation with HMG+LE was the only beneficial factor significantly associated with clinical pregnancy (OR 1.929, 95% CI 1.068~3.485, P=0.029) and live birth (OR 2.255, 95% CI 1.188~4.282, P=0.013). Conclusion: Ovarian stimulation using HMG combined with LE can increase the clinical outcomes (live birth and clinical pregnancy) among infertile patients undergoing AIH due to explained or mild male factors.

BACKGROUND: Compared to adult studies, studies which involve the treatment of pediatric congenital hypogonadotropic hypogonadism (CHH) are limited and no universal treatment regimen is available. The aim of this study was to evaluate the feasibility of human chorionic gonadotropin (hCG)/human menopausal gonadotropin (hMG) therapy for treating male adolescents with CHH. METHODS: Male adolescent CHH patients were treated with hCG/hMG (nâ=â20) or a gonadotropin-releasing hormone (GnRH) pump (nâ=â21). The treatment was divided into a study phase (0-3 months) and a follow-up phase (3-12 months). The testicular volume (TV), penile length (PL), penis diameter (PD), and sex hormone levels were compared between the two groups. The TV and other indicators between the groups were analyzed using a t-test (equal variance) or a rank sum test (unequal variance). RESULTS: Before treatment, there was no statistical difference between the two groups in terms of the biochemistry, hormones, and other demographic indicators. After 3 months of treatment, the TV of the hCG/hMG and GnRH groups increased to 5.1â±â2.3âmL and 4.1â±â1.8âmL, respectively; however, the difference was not statistically significant (P > 0.05, tâ=â1.394). The PL reached 6.9â±â1.8âcm and 5.1â±â1.6âcm (Pâ<â0.05, tâ=â3.083), the PD reached 2.4â±â0.5âcm and 2.0â±â0.6âcm (Pâ<â0.05, tâ=â2.224), respectively, in the two groups. At the end of 6 months of treatment, biomarkers were in normal range in the two groups. Compared with the GnRH group, the testosterone (T) level and growth of PL and PD were significantly greater in the hCG/hMG group (all Pâ<â0.05). While the TV of both groups increased, the difference was not statistically significant (Pâ>â0.05, tâ=â0.314). After 9 to 12 months of treatment, the T level was higher in the hCG/hMG group. Other parameters did not exhibit a statistical difference. CONCLUSIONS: The hCG/hMG regimen is feasible and effective for treating male adolescents with CHH. The initial 3 months of treatment may be a window to optimally observe the strongest effects of therapy. Furthermore, results from the extended time-period showed positive outcomes at the 1-year mark; however, the long-term effectiveness, strengths, and weaknesses of the hCG/hMG regimen require further research.

Objective: To assess and compare the feasibility of progestin-primed ovarian stimulation (PPOS) protocol with mild stimulation protocol for advanced age women with diminished ovarian reserve (DOR) undergoing their first in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycle. Methods: Patients aged ≥35 years and DOR undergoing their first IVF/ICSI cycle were enrolled in this retrospective cohort study: 139 and 600 patients underwent the PPOS and mild stimulation protocols, respectively. The primary outcomes were cumulative clinical pregnancy rate (CCPR) and cumulative live birth rate (CLBR). The secondary outcomes were the number of oocytes retrieved and top-quality embryos. Results: There was nearly no significant difference of baseline characteristics between the two groups. Although a greater amount of total gonadotropin (1906.61 ± 631.04 IU vs. 997.72 ± 705.73 IU, P<0.001) and longer duration of stimulation (9 (10-7) vs. 6 (8-4), P<0.001) were observed in the PPOS group, the number of retrieved oocytes (3 (6-2) vs. 2 (4-1), P<0.001) and top-quality embryos (1 (2-0) vs. 1 (2-0), P=0.038) was greater in the PPOS group than the mild stimulation group. Meanwhile, the incidence of premature luteinizing hormone (LH) surge rate was significantly lower in the PPOS group (0.7% vs.8.3%, P=0.001) than the mild stimulation group. However, there was no significant difference in conservative CCPR, conservative CLBR, optimistic CCPR, and optimistic CLBR between the two groups (all P>0.05). A multivariate logistic regression model showed significant positive effects of the number of retrieved oocytes and number of top-quality embryos on conservative CCPR (OR=1.236, 95%CI: 1.048-1.456, P=0.012, OR=2.313, 95%CI: 1.676-3.194, P<0.001) and conservative CLBR (OR=1.250, 95%CI: 1.036-1.508, P=0.020, OR=2.634, 95%CI: 1.799-3.857, P<0.001) respectively, while significant negative effects of age were identified for conservative CCPR (OR=0.805, 95%CI: 0.739-0.877, P<0.001) and conservative CLBR (OR=0.797, 95%CI: 0.723-0.879, P<0.001). Conclusion: The PPOS protocol is an effective alternative to the mild stimulation protocol for advanced age patients with DOR, as it provides comparable reproductive outcomes and better control of premature LH surge. Further, more oocytes and top-quality embryos were obtained in the PPOS group, which had a positive association with conservative CCPR and CLBR.

INTRODUCTION: Turner syndrome (TS) is associated with hypergonadotropic hypogonadism due to gonadal dysgenesis, which results in premature ovarian failure and subsequent infertility. Therefore, counseling and evaluation for fertility preservation are required as early as possible for women with TS. CASE PRESENTATION: A 23-year-old unmarried woman with mosaic TS (45, X [4/30] 46, XX [26/30]) presented to the pediatric department of our hospital for fertility counseling; she was accompanied by her mother. She was referred to the reproduction center of our hospital for ovarian reserve assessment and counseling regarding fertility preservation. We decided to retrieve oocytes using DuoStim as the controlled ovarian stimulation protocol. During the first and second oocyte retrievals, a total of 17 (9 and 8, respectively) mature metaphase II oocytes were cryopreserved. CONCLUSION: DuoStim may be a useful option for fertility preservation for women with TS and reduced ovarian reserve. This new strategy may obtain the required number of oocytes in the shortest time and preserve the future fertility of women with TS.

OBJECTIVE: To systematically review the efficacy of a combination of recombinant follicle-stimulating hormone (rFSH) and recombinant luteinizing hormone (rLH) protocol versus human menopausal gonadotropin (hMG) protocol in controlled ovarian stimulation (COS). METHODS: PubMed, EMbase, The Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, and WanFang Data were searched to collect studies published prior to January 2019 on the efficacy of rFSH combined with rLH versus hMG alone in COS. Two reviewers independently screened the literature, conducted the data extraction, and assessed the risk of bias for all selected studies. Then, Review Manager 5.3 software was used for the meta-analysis. RESULTS: There were 2767 patients from 9 studies. The results showed that among patients aged >30 years for IUI, the combination of rFSH and rLH was superior to hMG alone in clinical pregnancy rate per patient (relative risk [RR] = 1.47, 95% confidence interval [CI] 1.02 to 2.12) and endometrial thickness (mean difference [MD] = 0.34, 95% CI 0.04 to 0.64). In patients over 30 years old who received IVF, the results tended to favor the combination of rFSH and rLH in clinical pregnancy rate per patient (RR = 4.48, 95% CI 1.15 to 17.46) and live birth rate per started cycle (RR = 1.69, 95% CI 1.96 to 2.71). In patients less than 30 years old who received IVF, the combination of rFSH and rLH was superior to hMG in the number of retrieved oocytes (MD = 3.70, 95% CI 3.27 to 4.13) and inferior to hMG in number of high-quality embryos (MD = -0.60, 95% CI -0.91 to -0.29). CONCLUSION: The combination of rFSH and rLH may have better efficacy than hMG alone in COS. However, considering the limited sample size of the included studies, the current evidence is not definitive.

OBJECTIVE: To evaluate the efficacy and safety of highly purified human menotropin (HP-hMG) and recombinant follicle-stimulating hormone (rFSH) for controlled ovarian stimulation in a population of patients predicted to be high responders. DESIGN: Randomized, open-label, assessor-blinded, parallel-group, noninferiority trial. SETTING: Fertility centers. PATIENT(S): A total of 620 women with serum antimüllerian hormone (AMH) ≥5 ng/mL. INTERVENTION(S): Controlled ovarian stimulation with HP-hMG or rFSH in a GnRH antagonist assisted reproductive technology (ART) cycle. Fresh transfer of a single blastocyst was performed unless ovarian response was excessive, in which all embryos were cryopreserved. Subjects could undergo subsequent frozen blastocyst transfer within 6 months of randomization. MAIN OUTCOME MEASURE(S): Ongoing pregnancy rate (OPR) after fresh transfer (primary endpoint), as well as cumulative live birth, ovarian hyperstimulation syndrome (OHSS), and pregnancy loss rates. RESULTS: OPR/cycle start after fresh transfer was 35.5% with HP-hMG and 30.7% with rFSH (difference: 4.7%, 95% CI -2.7%, 12.1%); noninferiority was established. Compared to rFSH, HP-hMG was associated with significantly lower OHSS (21.4% vs. 9.7% respectively; difference: -11.7%, 95% CI -17.3%, -6.1%) and cumulative early pregnancy loss rates (25.5% vs. 14.5% respectively; difference: -11.0%, 95% CI -18.8%, -3.14%). Despite 43 more transfers in the rFSH group, cumulative live birth rates were similar with HP-hMG and rFSH at 50.6% and 51.5% respectively (difference: -0.8%, 95% CI -8.7%, 7.1%). CONCLUSION(S): In high responders, HP-hMG provided comparable efficacy to rFSH with fewer adverse events, including pregnancy loss, suggesting its optimized risk/benefit profile in this population. CLINICAL TRIAL REGISTRATION NUMBER: NCT02554279 (clinicaltrials.gov).

This study aims at detecting and evaluating differences in quantitative response to controlled ovarian stimulation (COS) with high doses of gonadotropins in women with low serum anti-Müllerian hormone (AMH). About 369 first cycles in a real-life scenario in women between 21 and 43 years old and with AMH ≤0.9 ng/ml were analyzed. Older women had a significantly worse outcome with respect to young women, not only qualitatively, but also in terms of quantitative ovarian response to COS [odd ratio (OR) to obtain at least three MII oocytes with each increasing year of female age: 0.89, 95% CI: 0.85 - 0.94; p < .001]. This study endorses that age is a significant factor when counseling patients with low AMH. AMH levels per se are not a reason to exclude patients from a COS treatment, since pregnancy and live birth can be achieved, especially in younger patients. However, with an AMH equally low, the ovarian response worsens with age, making questionable the effectiveness of a stimulation with high-dose gonadotropins in the older subgroup.

OBJECTIVE: To compare the effects of letrozole and human menopausal gonadotropin (HMG) in the treatment of patients with polycystic ovary syndrome (PCOS) resistant to clomiphene citrate (CC). METHODS: A total of 96 clomiphene resistance polycystic ovary syndrome patients infertility were randomly divided into an LE group, and HMG group (nâ=â48). LE group orally received letrozole at 5.0âmg/d on the 3rd-5th days of menstrual cycle for 5 consecutive days, and 75âU/d HMG was given through intramuscular injection for 5 days starting from the third day of menstrual cycle in HMG group. Number of growing and mature follicles, serum E2â(pg/mL), serum P (ng/mL), endometrial thickness, occurrence of pregnancy and miscarriage were observed. RESULTS: There was no significant difference in the number of ovulation cycles between the 2 groups (53.6% vs 64.7%, Pâ>â.05). The number of mature follicular cycles in the HMG group was higher than that of the letrozole group (Pâ<â.01). There were no significant differences in the clinical pregnancy rate (22.9% vs 27.1%, Pâ>â.05) and abortion rate (6.2% vs 10.4%, Pâ>â.05). There was no significant difference in the endometrial thickness between the 2 groups on the day of HCG injection [(9.1â±â0.2)âmm vs (10.7â±â1.6)âmm, Pâ>â.05]; the serum estradiol (E2) was lower in the letrozole group. The incidence of ovarian cysts was lower than that of HMG group (Pâ<â.05). There was2 ovarian hyperstimulation syndrome in the letrozole group; the incidence of ovarian hyperstimulation syndrome in the HMG group was 12.5%. CONCLUSION: Letrozole-induced ovulation can obtain ovulation rate and pregnancy rate similar to gonadotropin, but reduce the risk associated with treatment. It can be used as an effective ovulation option for patients with polycystic ovary syndrome who are resistant to clomiphene.
