OBJECTIVE: To explore the effects of Zishen Yutai Pills (ZYPs) on the quality of oocytes and embryos, as well as pregnancy outcomes in patients with diminished ovarian reserve (DOR) receiving in vitro fertilization-embryo transfer (IVF-ET). The possible mechanisms, involving the regulation of bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9), were also investigated. METHODS: A total of 120 patients with DOR who underwent their IVF-ET cycle were randomly allocated to 2 groups in a 1:1 ratio. The patients in the treatment group (60 cases) received ZYPs from the mid-luteal phase of the former menstrual cycle by using gonadotropin-releasing hormone (GnRH) antagonist protocol. The patients in the control group (60 cases) received the same protocol but without ZYPs. The primary outcomes were the number of oocytes retrieved and high-quality embryos. Secondary outcomes included other oocyte or embryo indices as well as pregnancy outcomes. Adverse events were assessed by comparison of the incidence of ectopic pregnancy, pregnancy complications, pregnancy loss, and preterm birth. Contents of BMP15 and GDF9 in the follicle fluids (FF) were also quantified with enzyme-linked immunosorbent assay. RESULTS: Compared with the control group, the numbers of oocytes retrieved and high-quality embryos were significantly increased in the ZYPs group (both P<0.05). After treatment with ZYPs, a significant regulation of serum sex hormones was observed, including progesterone and estradiol. Both hormones were up-regulated compared with the control group (P=0.014 and 0.008), respectively. No significant differences were observed with regard to pregnancy outcomes including implantation rates, biochemical pregnancy rates, clinical pregnancy rates, live birth rates, and pregnancy loss rates (all P>0.05). The administration of ZYPs did not increase the incidence of adverse events. The expressions of BMP15 and GDF9 in the ZYPs group were significantly up-regulated compared with the control group (both P<0.05). CONCLUSIONS ZYPs exhibited beneficial effects in DOR patients undergoing IVF-ET, resulting in increments of oocytes and embryos, and up-regulation of BMP15 and GDF9 expressions in the FF. However, the effects of ZYPs on pregnancy outcomes should be assessed in clinical trials with larger sample sizes (Trial reqistration No. ChiCTR2100048441).

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

OBJECTIVE: To evalvate efficacy of Qizi Yusi Pills (QYP), a Chinese medicine compound preparation, on in vitro fertilization-embryo transfer (IVF-ET) in women of advanced reproductive age. METHODS: This multicenter, randomized, double-blind, placebo-controlled trial was conducted from June 2018 to October 2019. A total of 124 patients were randomly allocated to either the QYP group or the placebo group using a stratified block randomization design, with 62 patients in each group. All patients completed controlled ovarian stimulation using a standard gonadotropin-releasing hormone agonist (GnRH-a) long protocol. As the QYP group, QYP was administered while the control group received placebo. QYP and placebo were administered for a total of 24 to 30 days from the day of GnRH-a pituitary downregulation to transvaginal oocyte retrieval. Both medications were taken orally at doses of 10 g three times each day. The primary outcome was cumulative pregnancy rate, and the secondary outcomes were periodic medication, follicular status, serum hormone and endometrial receptivity. Follow-up continued until 4 weeks after delivery. Maternal and neonatal complications, such as gestational diabetes, were also observed. RESULTS: Overall, 119 patients completed the study, 60 in the QYP group and 59 in the placebo group. Per protocol (PP) analysis revealed that 6-month cumulative pregnancy rate in the QYP group was significantly higher than that in the placebo group [43.33% (26/60) vs. 25.42% (15/59), P=0.040). Additionally, more oocytes were retrieved from the QYP group than those from the placebo group (8.95 ± 3.12 vs. 7.85 ± 1.91, P=0.022). Moreover, the endometrial thickness of HCG day in the QYP group was significantly higher than that in the placebo group (11.78 ± 2.27 mm vs. 10.68 ± 2.07 mm, P=0.012). Maternal and neonatal complications between the two groups were not significantly different (P>0.05). Intention-to-treat analysis was in line with PP results. CONCLUSIONS QYP can enhance ovarian reserve capacity and ovarian response, and possibly promote endometrial receptivity. QYP effectively improves cumulative pregnancy rates in older patients (⩾35 years) undergoing IVF-ET. (Registration No. ChiCTR1800014427).

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 (n = 20) or a gonadotropin-releasing hormone (GnRH) pump (n = 21). 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 5.1 ± 2.3 mL and 4.1 ± 1.8 mL, respectively; however, the difference was not statistically significant (P > 0.05, t = 1.394). The PL reached 6.9 ± 1.8 cm and 5.1 ± 1.6 cm (P < 0.05, t = 3.083), the PD reached 2.4 ± 0.5 cm and 2.0 ± 0.6 cm (P < 0.05, t = 2.224), 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 P < 0.05). While the TV of both groups increased, the difference was not statistically significant (P > 0.05, t = 0.314). 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.

To evaluate the efficacy and safety of aromatase inhibitor letrozole in treatment of male adolescents with idiopathic short stature (ISS). Seventy five boys with height less than 2 standard deviation (SD) below the mean who had entered puberty were enrolled in our study from 2004 to 2017, in the Pediatric Department of the First Affiliated Hospital, Sun Yat-Sen University. Among 75 patients, 28 in letrozole group received letrozole and spironolactone, 30 in gonadotrophin releasing hormone analogue (GnRHa) group received GnRHa injection and 17 had no intervention. Height velocity (HV), increment of bone age/chronological age (ΔBA/ΔCA), the final adult height (FAH) were compared among groups and the safety of letrozole treatment was evaluated. HV maintained faster during letrozole treatment when compared with other groups. HV during GnRHa treatment showed slightly decline in the first 6 months, but decreased remarkably after 6 months, and was significantly lower than that in letrozole group ( < 0.05). The maturation of BA slowed down in both letrozole and GnRHa groups. But the ΔBA/ΔCA in letrozole group during the first and the second year of treatment were significantly higher (0.67±0.09, 0.50±0.15, respectively) when compared with GnRHa group (0.59±0.16, 0.44±0.13, respectively) ( =2.78 and 2.20, all < 0.05). FAH in letrozole group and GnRHa group were (170±4) cm and (170±6)cm, there was no significant differences between the two groups ( >0.05), and both were higher than that in no intervention group (162±4 cm, < 0.01). After 6 months of letrozole treatment, testicular volumes and serum testerone levels increased; 39.2% (11/28) boys had clinical manifestations of hyperandrogenemia, and 82.1% (23/28) boys had decreased serum high-density lipoprotein (HDL) levels. Serum levels of HDL and testerone returned normal and the hyperandrogenemia disappeared after the cessation of letrozole treatment. No significant changes in serum triglyceride, serum low-density lipoprotein (LDL), fating serum levels of insulin and glucose, HOMA-IR were observed. No abnormal liver function, myalgia, scoliosis or aggravations of scoliosis was found. Long term letrozole therapy during puberty in boys with ISS can delay bone maturation without significant decrease of linear growth, and thus can improve the final adult height. No severe adverse reactions were found.

Pulsatile gonadotropin-releasing hormone (GnRH) may induce spermatogenesis in most patients with congenital hypogonadotropic hypogonadism (CHH) by stimulating gonadotropin production, while the predictors for a pituitary response to pulsatile GnRH therapy were rarely investigated. Therefore, the aim of our study is to investigate predictors of the pituitary response to pulsatile GnRH therapy. This retrospective cohort study included 82 CHH patients who received subcutaneous pulsatile GnRH therapy for at least 1 month. Patients were categorized into poor or normal luteinizing hormone (LH) response subgroups according to their LH level (LH <2 IU l^-1 or LH ≥2 IU l^-1) 1 month into pulsatile GnRH therapy. Gonadotropin and testosterone levels, testicular size, and sperm count were compared between the two subgroups before and after GnRH therapy. Among all patients, LH increased from 0.4 ± 0.5 IU l^-1 to 7.5 ± 4.4 IU l^-1 and follicle-stimulating hormone (FSH) increased from 1.1 ± 0.9 IU l^-1 to 8.8 ± 5.3 IU l^-1. A Cox regression analysis showed that basal testosterone level (β = 0.252, P = 0.029) and triptorelin-stimulated FSH_60min(β = 0.518, P = 0.01) were two favorable predictors for pituitary response to GnRH therapy. Nine patients (9/82, 11.0%) with low LH response to GnRH therapy were classified into the poor LH response subgroup. After pulsatile GnRH therapy, total serum testosterone level was 39 ± 28 ng dl^-1 versus 248 ± 158 ng dl^-1 (P = 0.001), and testicular size was 4.0 ± 3.1 ml versus 7.9 ± 4.5 ml (P = 0.005) in the poor and normal LH response subgroups, respectively. It is concluded that higher levels of triptorelin-stimulated FSH_60minand basal total serum testosterone are favorable predictors of pituitary LH response to GnRH therapy.

PURPOSE: Docetaxel-based chemotherapy (DTX) improves overall survival (OS) of men with metastatic castration-resistant prostate cancer (mCRPC). Considering the potential existence of androgen receptors that remain active at this stage, we aimed to assess the impact of the combined use of androgen deprivation therapy (ADT) with DTX for mCRPC. MATERIALS AND METHODS: We performed a single-institutional retrospective analysis of patients with mCRPC who received either DTX alone (DTX group, n=21) or concurrent DTX and ADT (DTX+ADT group, n=26) between August 2006 and February 2014. All patients received DTX doses of 75 mg/m2 every three weeks for at least three cycles. In the DTX+ADT group, all patients used luteinizing hormone releasing hormone agonist continuously as a concurrent ADT. RESULTS: The median follow-up period was 24.0 months (interquartile range 12.0-37.0) for the entire cohort. The median radiographic progression-free survival (rPFS) was 9.0 months and 6.0 months in the DTX+ADT and DTX groups, respectively (log-rank p=0.036). On multivariable Cox regression analysis, concurrent administration of ADT was the only significant predictor of rPFS [hazard ratio (HR)=0.525, 95% confidence intervals (CI) 0.284-0.970, p=0.040]. The median OS was 42.0 and 38.0 months in the DTX+ADT and DTX groups, respectively (log-rank p=0.796). On multivariable analysis, hemoglobin level at the time of DTX initiation was associated with OS (HR=0.532, 95% CI 0.381-0.744, p<0.001). CONCLUSION: In chemotherapy-naive patients with mCRPC, the combined use of ADT with DTX improved rPFS. Our result suggests that the concurrent administration of ADT and DTX is superior to DTX alone.

Endometrial hyperplasia (EH) comprises a spectrum of changes in the endometrium ranging from a slightly disordered pattern that exaggerates the alterations seen in the late proliferative phase of the menstrual cycle to irregular, hyperchromatic lesions that are similar to endometrioid adenocarcinoma. Generally, EH is caused by continuous exposure of estrogen unopposed by progesterone, polycystic ovary syndrome, tamoxifen, or hormone replacement therapy. Since it can progress, or often occur coincidentally with endometrial carcinoma, EH is of clinical importance, and the reversion of hyperplasia to normal endometrium represents the key conservative treatment for prevention of the development of adenocarcinoma. Presently, cyclic progestin or hysterectomy constitutes the major treatment option for EH without or with atypia, respectively. However, clinical trials of hormonal therapies and definitive standard treatments remain to be established for the management of EH. Moreover, therapeutic options for EH patients who wish to preserve fertility are challenging and require nonsurgical management. Therefore, future studies should focus on evaluation of new treatment strategies and novel compounds that could simultaneously target pathways involved in the pathogenesis of estradiol-induced EH. Novel therapeutic agents precisely targeting the inhibition of estrogen receptor, growth factor receptors, and signal transduction pathways are likely to constitute an optimal approach for treatment of EH.

Long-term gonadotropin-releasing hormone agonist (GnRHa) administration before in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) in infertile women with endometriosis or adenomyosis significantly enhanced the chances of pregnancy in both fresh and frozen embryo transfer cycles. We hypothesized that long-term GnRHa treatment might also be beneficial for the idiopathic repeated implantation failure (RIF) patients. In the 21 patients receiving GnRHa and hormone replacement therapy (G-HRT) protocols for frozen embryo transfer, their data were compared with those of the 56 of frozen/fresh cycles they had previously undergone (previous protocols). Comparison showed that the finial results were significantly better with G-HRT protocols than with their previous protocols, with pregnancy rate, clinical pregnancy rate, implantation rate and on-going pregnancy rate being 70%, 60%, 40% and 38% respectively with G-HRT protocols, against 17%, 11%, 6.3% and 5% with previous protocols. The results showed that hormonally controlled endometrial preparation with prior GnRHa suppression could be used for patients who had experienced repeated failures of IVF treatment despite having morphologically optimal embryos, and the treatment may help increase the receptivity of the endometrium in these patients.
