A prospective study on the endometrium properties and the pregnancy rate of infertile women with thin endometrium receiving Fructus ligustri lucidi used in traditional Chinese medicine.

OBJECTIVE: To evaluate whether Zi Gui Nv Zhen capsules (ZGNZC) can increase the fertility rate of Chinese women with infertility due to thin endometrium. METHODS: Prospective, randomized, open-labeled 3-monthly study; 104 patients (aged 20-40 years) receiving either ZGNZC (experimental group, n = 55) or not (control group, n = 49). Main outcomes: thickness/type of the endometrium during ovulation and pregnancy rate. Between-group analysis (A) compares the experimental vs. control group, and within-group analysis (B) compares data at baseline and after study in the experimental group. RESULTS: (A) Between-group-analysis: Patients with ZGNZC had a higher endometrium thickness (0.8 ± 0.27 vs. 0.68 ± 0.10; p < .05) and higher type A endometrium rates (34.2% vs. 13.2%; p < .05) than the control group. Pregnancy rates were higher in the experimental than in the control group (43.6% vs. 22.4%; p < .05). (B) Within-group-analysis: ZGNZC increased endometrium thickness (0.58 ± 0.13 vs. 0.87 ± 0.24 vs. 0.83 ± 0.26 vs. 0.80 ± 0.27), and type A endometrium rates (10.9% vs. 60.0% vs. 49.0% vs. 34.2%) (all p < .05). Univariate analysis of pregnancy with other study parameters showed positive and significant correlations between pregnancy and administration of ZGNZC (p < .05). All hepato-renal biomarkers remained within the norm. There were no adverse events. CONCLUSIONS: In infertile women with thin endometrium who wish to conceive, two months' application of ZGNZC can improve endometrial properties and proliferation, which is necessary for a healthy pregnancy, and increase the clinical pregnancy rate in our prospective randomized observational study.

The effect of Kuntai capsule on ovarian function in cisplatin-induced premature ovarian insufficiency rats.

Objective: This study aims to evaluate the effect of Kuntai capsule on ovarian function in cisplatin-induced premature ovarian insufficiency rats and to explore the mechanism of Kuntai capsule on the ovarian function of rats. Methods: Seventy-four female Sprague-Dawley rats were used for this study. Eight of the rats were randomly assigned to the Control group. The remaining sixty-six rats were utilized to establish the POI model via Cisplatin and then randomly divided into four groups: the model Control group, the Estradiol group, and groups treated with low and high doses of Kuntai capsule. For the 28-day administration, the Control and model Control groups were intragastrically administered with 2.0 mL of 0.9% sodium chloride daily, the Estradiol group with 2.0 mL of Estradiol suspension (0.2mg/kg/d), and the low dose Kuntai capsule group and the high dose Kuntai capsule group with 2.0 mL of Kuntai capsule suspension (0.6g/kg/d, 1.8g/kg/d, respectively). Sex hormone levels, estrous cycle, and ovarian coefficient of the five groups were compared, histological sections analyzed follicle counts, and the protein expressions of growth differentiation factor 9, light chain 3 A-II, and Beclin 1 in the ovarian tissue were detected by Western blotting. Results: After the 28-day administration, the serum Estradiol and Follicle-Stimulating Hormone levels of the group treated with low dose of Kuntai capsule were not significantly different from the Control group, the serum anti-Müllerian Hormone level of the group treated with high dose of Kuntai capsule was significantly higher than the Estradiol group. The estrous cycle of the group treated with low dose of Kuntai capsule was significantly lower than the model Control group. Regarding ovarian coefficient, resting and growing follicles, growth differentiation factor 9, light chain 3 A-II, and Beclin 1 expression, both Kuntai capsule groups outperformed the model Control group with the statistical difference (P<0.05). Conclusion: Kuntai capsule can improve the estrous cycle and ovarian coefficient of rats with premature ovarian insufficiency, maintain the number of resting and growing follicles, and up-regulate the protein expression of growth differentiation factor 9, light chain 3 A-II, and Beclin 1 of rats' ovaries.

Efficacy and safety of Zi Gui Nv Zhen® capsules used in TCM for fertility preservation in patients with diminished ovarian reserve.

OBJECTIVE: To evaluate for the first time whether Zi Gui Nv Zhen® capsules (ZGNZC), until now used in traditional Chinese medicine (TCM) for menopausal complaints, can increase the fertility of Chinese women with diminished ovarian reserve (DOR). METHODS: Prospective, randomized, open-labeled 3-monthly study; 109 DOR patients (aged 20-40 years) receiving either ZGNZC (experimental group, n = 75) or not (control group, n = 34). Main outcomes: markers for ovarian function, thickness/type of the endometrium during ovulation, and pregnancy rate. Between-group analysis (A) comparing experimental vs. control group and within-group analysis (B) comparing data at baseline and after study in each of both groups. RESULTS: (A) Between-group-analysis: patients with ZGNZC had a higher endometrium thickness (0.75 vs. 0.62; p<.05) and higher anti-Müllerian hormone (AMH, 0.50 vs. 0.40; p<.05) than control group. Pregnancy rates were higher in the experimental than the control group (26.7% vs. 14.7%; n.s.). (B) Within-group-analysis: ZGNZC decreased levels of follicle-stimulating hormone (FSH, 11.42 vs. 8.69), increased estradiol-levels (E2, 56.09 vs. 73.36), and type A endometrium rates (5.3% vs. 39.7%) (all p< .05) and increased antral follicle count (AFC, 2 vs. 3). All hepato-renal biomarkers remained within the norm. The tolerability was good. There were no adverse events. CONCLUSIONS: In women with DOR who wish to conceive, three months' application of ZGNZC can improve ovarian function and oocyte quality by adjusting the neuroendocrine system, can improve endometrial properties and proliferation, necessary for a healthy pregnancy, and increased the clinical pregnancy rate in our prospective randomized observational study.
