OBJECTIVE: To study the clinical efficacy of Wenyang Lishui Formula (WYLSF) in preventing ovarian hyperstimulation syndrome (OHSS) and explore the suitable range of estradiol (E₂) on the human chorionic gonadotropin (HCG) day in patients with OHSS using WYLSF. METHODS: Part I: eligible patients at high risk for OHSS undergoing ovulation induction between January and December, 2023 were randomized into 2 groups based on the actual treatment. The treatment group received 200 mL WYLSF formula twice daily for 5 days after oocyte retrieval in a combination of lifestyle coaching (LC) intervention including regular diet and exercise, whereas the LC group received LC intervention alone. The incidence of OHSS, OHSS self-assessment scales, changes in E₂ levels on HCG day and 5 days after oocyte retrieval, ovarian morphology changes, and menstrual recovery were compared between the two groups. Part II: patients at high risk for OHSS treated with WYLSF were studied. The optimal E₂ threshold on the HCG day was determined using the maximum selection test, and a multivariate analysis was adopted to compare the relationship between different E₂ levels on HCG day and hospitalization rate, incidence of moderate to severe OHSS, and self-assessment scales, to explore the preventive effect of WYLSF on OHSS in patients with varying E₂ levels. RESULTS: A total of 120 patients were included in the Part I analysis. The treatment group (60 cases) showed a significant reduction in the incidence, duration, and severity of abdominal distension, as well as the incidence of vomiting compared with the LC group (P<0.05). The post-retrieval E₂ levels in the treatment group decreased significantly more (P=0.032). Among 1,652 patients treated with WYLSF in the Part II, 90 patients with ⩽ 10092 pmol/L, 159 with >31074 pmol/L, and 1,403 in the middle range group were formed based on E₂ levels on HCG day in Part two analysis. Univariate and regression analyses showed that patients with E₂ levels >31073 pmol/L had a significantly higher incidence of moderate to severe OHSS compared to those with E₂ levels ⩽ 10092 pmol/L (P<0.05). CONCLUSIONS WYLSF can effectively reduce specific symptoms in high-risk OHSS patients after ovulation induction and significantly lower E₂ levels. It may be more suitable for high-risk OHSS patients with E₂ levels <31073 pmol/L on HCG day. (Registration No. MR-11-23-032493, https://www.medicalresearch.org.cn/login ).

OBJECTIVES: Platelet-rich plasma (PRP) treatment has been reported to improve ovarian function in women, but the relationship between the dose and frequency of PRP treatment and its therapeutic effect remains unclear. This study aims to evaluate the efficacy of single and double PRP treatments for diminished ovarian reserve (DOR). METHODS: A total of 65 patients treated at the Reproductive Center of Xiangtan Central Hospital from September 2020 to October 2022 were randomly divided into 4 groups: A single PRP treatment group (21 patients, PRP treatment once), a double PRP treatment group (15 patients, PRP treatment twice), a blank control group (15 patients), and an artificial cycle control group (14 patients, treated with estrogen and progesterone). The differences in baseline follicle-stimulating hormone (FSH), antral follicle count (AFC), ovarian volume, number of oocytes retrieved, number of good quality embryos, and pregnancy outcomes before and after treatment were compared among the 4 groups. RESULTS: Compared to before treatment, both single and double PRP treatment groups showed a significant reduction in FSH, and an increase in AFC, ovarian volume, numbers of oocytes retrieved, and number of MII oocytes (all P<0.05). Compared to the blank control group, the single and double PRP groups showed a decrease in FSH, with an increase in AFC, number of oocytes retrieved, and number of MII oocytes (all P<0.05). The rates of good quality embryos, clinical pregnancy rate, and live birth rate in the single and double PRP groups were higher than those in the blank control group and artificial cycle control groups, but the differences were not statistically significant (all P>0.05). Compared to the single PRP treatment group, the double PRP group had lower FSH and higher AFC, but the differences were not statistically significant (both P>0.05). CONCLUSIONS Both single and double PRP ovarian injections can effectively improve ovarian reserve function in DOR patients and enhance ovarian response. Compared to single PRP ovarian injection, double PRP ovarian injection shows a trend of better improvement in ovarian reserve function.

OBJECTIVES: To evaluate the association of GGN repeat polymorphism of androgen receptor (AR) with ovarian reserve and ovarian response in controlled ovarian stimulation (COS). METHODS: This genetic association study was conducted among a total of 361 women aged ≤40 years with basal FSH≤12 U/L undergoing the GnRH-agonist long protocol for COS in a university-affiliated IVF center. GGN repeat in the AR gene was analyzed with Sanger sequencing. The primary endpoint was the number of antral follicle counts (AFCs), and the secondary endpoints were stimulation days, total dose of gonadotropin (Gn) used, total number of retrieved oocytes, ovarian sensitivity index, and follicular output rate. RESULTS: The GGN repeat in exon 1 of the AR gene ranged from 13 to 24, and the median repeat length was 22. Based on the genotypes (S for GGN repeats <22, L for GGN repeats ≥22), the patients were divided into 3 groups: SS, SL, and LL. Generalized regression analysis indicated that the number of AFCs in group SS was significantly lower than those in group SL (adjusted β=1.8, 95% CI: 0.2-3.4, P=0.024) and group LL (adjusted β=1.5, 95% CI: 0.2-2.7, P=0.021). No significant difference was observed in the number of AFCs between group SL and group LL (P>0.05). Generalized regression analysis indicated no significant differences in ovarian stimulation parameters among the 3 groups, either before or after adjusting for confounding factors (P>0.05). CONCLUSIONS GGN repeat length on the AR gene is associated with AFC but not with ovarian response in Chinese women, indicating that AR gene polymorphisms may affect ovarian reserve.

OBJECTIVES: To explore the effects of exogenous trigger (hCG/GnRHa) versus endogenous LH surge in natural cycle IVF/ICSI (NC-IVF/ICSI) for patients with diminished ovarian reserve (DOR). METHODS: A retrospective analysis was conducted on 1,118 NC-IVF/ICSI cycles from two reproductive centers between 2013 and 2024. Propensity score matching (PSM) and multivariate logistic regression were used to adjust for confounding factors. The trigger-day hormone threshold was determined using receiver operating characteristic (ROC) curve analysis. Outcome measures included oocyte retrieval rate, 2PN fertilization rate, clinical available embryo rate, high-quality embryo rate, fresh cycle clinical pregnancy rate (CPR), and live birth rate (LBR). RESULTS: After adjusting for confounders via PSM and logistic regression, the exogenous trigger group demonstrated significantly better outcomes across all the evaluated parameters (oocyte retrieval rate, 2PN fertilization rate, transferable embryo rate, high-quality embryo rate, fresh cycle CPR, and LBR) than the endogenous LH surge group (P<0.05). Age-stratified analysis revealed that for the entire cohort, exogenous triggering significantly increased the number of transferable embryos and high-quality embryos (P<0.001). In the 35-39 years old subgroup, exogenous triggering showed significant advantages in oocyte yield, high-quality embryo rate, CPR, and LBR (P<0.05) and resulted in the most pronounced improvement in LBR (OR=6.25, 95% CI: 1.34-29.23). ROC analysis established a decision-day LH threshold of 19.055 mIU/mL (AUC=0.945, specificity=93.3%) for precise stratification of the clinical pathways. CONCLUSIONS For DOR patients undergoing NC-IVF/ICSI, exogenous triggering comprehensively improves the treatment outcomes, particularly providing significant live birth benefits for women aged 35-40 years. An individualized protocol incorporating the LH threshold (19.055 mIU/mL) effectively enhances embryonic developmental potential and live birth rates.

Polycystic ovary syndrome (PCOS) is the predominant cause of subfertility in reproductive-aged women; however, its pathophysiology remains unknown. Neurotensin (NTS) is a member of the gut-brain peptide family and is involved in ovulation; its relationship with PCOS is unclear. Here, we found that NTS expression in ovarian granulosa cells and follicular fluids was markedly decreased in patients with PCOS. In the in vitro culture of cumulus-oocyte complexes, the neurotensin receptor 1 (NTSR1) antagonist SR48692 blocked cumulus expansion and oocyte meiotic maturation by inhibiting metabolic cooperation and damaging the mitochondrial structure in oocytes and surrounding cumulus cells. Furthermore, the ERK1/2-early growth response 1 pathway was found to be a key downstream mediator of NTS/NTSR1 in the ovulatory process. Animal studies showed that in vivo injection of SR48692 in mice reduced ovulation efficiency and contributed to irregular estrus cycles and polycystic ovary morphology. By contrast, NTS partially ameliorated the ovarian abnormalities in mice with dehydroepiandrosterone-induced PCOS. Our findings highlighted the critical role of NTS reduction and consequent abnormal NTSR1 signaling in the ovulatory dysfunction of PCOS, suggesting a potential strategy for PCOS treatment.

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).

Hypoxia inducible factor-1α (HIF-1α), as a hypoxia inducible factor, affects women's reproductive function by regulating the development and excretion of follicles. HIF-1α induces glycolysis and autophagy in the granule cells by promoting oocyte development, regulating the secretion of related angiogenic factors, and improving follicle maturity. In addition, HIF-1α promotes the process of luteinization of follicular vesicles, maintains luteal function, and finally completes physiological luteal atrophy through cumulative oxidative stress. Dysfunction of HIF-1α will cause a series of pathological consequences, such as angiogenesis defect, energy metabolism abnormality, excessive oxidative stress and dysregulated autophagy and apoptosis, resulting in ovulation problem and infertility. This article summarizes the previous studies on the regulation of follicle development and excretion and maintenance of luteal function and structural atrophy by HIF-1α. We also describe the effective intervention mechanism of related drugs or bioactive ingredients on follicular dysplasia and ovulation disorders through HIF-1α, in order to provide a systematic and in-depth insights for solving ovulation disorder infertility.

OBJECTIVE: To observe the effect of acupuncture on endometrium and pregnancy outcomes in patients with polycystic ovary syndrome (PCOS) infertility undergoing in vitro fertilization-embryo transfer (IVF-ET). METHODS: Eighty-three patients were randomly assigned to observation group (40 cases) and control group (43 cases) according to the random numbers generated by SPSS software. The patients of the two groups received GnRH agonist long protocol as a routine treatment. In the observation group, acupuncture was given at two acupoint groups for 30 min once every other day. Group 1 included Guanyuan (CV 4), Qihai (CV 6), Zhongji (CV 3), bilateral acupoints Zigong (EX-CA1). Group 2 included Mingmen (GV 4), Yaoyangguan (GV 3), bilateral Shenshu (BL 23) and Ciliao (BL 32). The two groups of acupoints were used alternately. The whole needling process was performed at the time of ovulation induction until the transplantation day and consisted of 3 courses, while the control group did not receive acupuncture interventions. The Gn dosage and Gn stimulation time, endometrial thickness and type (A, B, and C), serum oestradiol (E2) and progesterone (P) levels on the day of injection of human chorionic gonadotropin (hCG), clinical pregnancy rate, as well as live birth rate were observed. Adverse reactions were also be recorded. All patients were followed up for the pregnant rate 14 days after IVF-ET and live birth rate after pregnancy. All adverse reactions (AEs) of acupuncture were recorded during the trial. RESULTS: The Gn dosage and Gn stimulation time in the observation group were lower in the observation group than in the control group (P<0.01). The proportion of type A endometrium in the observation group were higher than that in the control group (P<0.05). The serum E₂ and P levels on the day of hCG injection was lower and the clinical pregnancy rate was higher in the observation group compared to those in the control group (P<0.05). There was no serious AEs during this trial. CONCLUSION Acupuncture can improve the proportion of type A endometrium, regulate the levels of serum E₂ and P on the day of hCG injection, and improve the pregnancy rate in patients with PCOS infertility undergoing IVF-ET.

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).

This paper discussed the guiding significance of "disease-syndrome-symptom" mode in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) for dealing with ovulation disorder infertility caused by hyperprolactinemia(HPRL). FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) concentrates on the disease entities, main symptoms, pathogenesis, and syndrome differentiation, based on which the prescriptions are prescribed. This reflects the "disease-syndrome-symptom" mode, with the core lying in the "combination of disease with syndrome". The contained Discussion on Menstruation Regulation(Tiao Jing Pian) and Discussion on Getting Pregnant(Zhong Zi Pian) have important reference significance for later doctors in the diagnosis and treatment of inferti-lity, and many prescriptions are still in use due to good effects. It is believed in traditional Chinese medicine(TCM) that HPRL results from kidney deficiency and liver depression, among which kidney deficiency is the main cause. Liver depression accelerates the onset of HPRL, so the kidney-tonifying and liver-soothing herbs were mainly selected. The "disease-syndrome-symptom" mode in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) sheds enlightenment on the diagnosis and treatment of ovulation infertility caused by HPRL, in that it is not confined to disease entity and syndrome type. The integration of "disease-syndrome-symptom" highlights the main complaint of patients and emphasizes the main pathogenesis, thus giving full play to the overall advantage of syndrome differentiation. For multiple diseases in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) such as infertility due to liver depression, infertility due to obesity, delayed menstruation, and irregular menstruation, although the typical lactation symptom of HPRL is not mentioned, the medication can still be determined according to the chief complaint, syndrome type, and symptoms and signs, making up for the defects of excessive reliance on serum biochemical indicators in modern Chinese medicine. We should learn its diagnosis and treatment thoughts of paying attention to liver, spleen, kidney, and heart, holism, and strengthening body resistance to eliminate pathogenic factors.
