Treatment Progress in Diminished Ovarian Reserve: Western and Chinese Medicine

The effect and mechanism of Zigui-Yichong-Fang on improving ovarian reserve in premature ovarian insufficiency by activating SIRT1/Foxo3a pathway.

Abstract Our study aims to investigate the efficacy and clinical significance of the Zuogui pill (ZGP) on premature ovarian failure (POF) via the GDF-9/Smad2 pathway. Changes in clinical symptoms in the control group (treated with Femoston alone) and the treatment group (treated with ZGP combined with Femoston) were assessed before and after treatment. Sex hormone levels, serum inflammatory cytokine levels, and ultrasound parameters were measured before and after treatment. POF rat models were established using cyclophosphamide and the POF rats were treated with Femoston, or ZGP combined with Femoston. GDF-9 and Smad2 expression levels were determined by RT-qPCR. The follicle-stimulating hormone (FSH), luteinizing hormone (LH), interleukin (IL)-6, and IL-21 levels, and the pulsatility index (PI) and resistance index (RI) values were decreased, while the estradiol (E2) and anti-Mullerian hormone (AMH) levels, antral follicle count (AFC), ovarian volume (OV), mean ovarian diameter (MOD), and peak systolic velocity (PSV) values were increased in the treatment group compared to the control group. After treatment with ZGP combined with Femoston, GDF-9 and Smad2 expression in the ovarian tissues of POF rats increased. ZGP has a therapeutic effect on POF via modulation of the GDF-9/Smad2 pathway.

Efficacy and Clinical Significance of the Zuogui Pill on Premature Ovarian Failure via the GDF-9/Smad2 Pathway

This study aims to explore the impact of Rehmannioside D (RD) on ovarian functions of rats with diminished ovarian reserve (DOR) and its underlying mechanisms of action. A single injection of cyclophosphamide was performed to establish a DOR rat model, and fourteen days after the injection, the rats were intragastrically administrated with RD for two weeks. Rat estrus cycles were tested using vaginal smears. Ovarian tissues were histologically evaluated, the number of primordial, mature, and atretic follicles was calculated, and the apoptotic rate of granulosa cells. Follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels were determined by ELISA assays. Protein levels of Forkhead Box O1 (FOXO1), KLOTHO, Bcl-2, and Bax were investigated in ovarian tissues of DOR rats. The binding between FOXO1 and KLOTHO was verified by ChIP assay. High-dose administration of RD into DOR rats improved their estrus cycles, increased ovarian index, enhanced the number of primordial and mature follicles, reduced the number of atretic follicle number, and ovarian granulosa cell apoptosis in addition to inhibiting FSH and LH levels and upregulating E2 expression. FOXO1 and KLOTHO were significantly suppressed in DOR rats. FOXO1 knockdown partially suppressed the protective effects of RD on DOR rats, and KLOTHO overexpression could restore RD-induced blockade of DOR development despite knocking down FOXO1. FOXO1 antibody enriched KLOTHO promoter, and the binding between them was reduced in DOR group compared to that in sham group. RD improved ovarian functions in DOR rats and diminished granulosa cell apoptosis via the FOXO1/KLOTHO axis.

The role of Erzhi Tiangui formula in expected poor ovarian responders undergoing in vitro fertilization-embryo transfer: A multicenter, randomized, double-blind, placebo-controlled trial

To explore the therapeutic effect of Bushen Yiqi Huoxue Decoction (补肾益气活血方 BYHD) in patients with diminished ovarian reserve (DOR). A total of 180 patients with DOR diagnosed from December 2013 to December 2014 were equally assigned into progynova and duphaston (E+D) group, Zuogui Pill (左归丸) group and BYHD group with 60 cases in each by computerized randomization. Patients received E+D, Zuogui Pill or BYHD for 12 months, respectively. Follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), anti-Mullerian hormone (AMH), antral follicle count (AFC), ovarian volume, endometrial thickness, and the resistance indices (RIs) of ovarian arteries and uterine arteries were observed before and after treatment. Nine women (4 from the E+D group, 3 from the Zuogui Pill group, and 2 from the BYHD group) withdrew from the study. After 6 months, Zuogui Pill and BYHD significantly decreased FSH and LH and increased endometrial thickness and AMH (all P<0.01). BYHD also resulted in E2 elevation (P<0.05), ovary enlargement (P<0.05), AFC increase (P<0.01), and RI of ovarian arteries decrease (P<0.05). After 12 months, further improvements were observed in the Zuogui Pill and BYHD groups (all P<0.01), but BYHD showed better outcomes, with lower FSH, larger ovaries and a thicker endometrium compared with the Zuogui Pill group (all P<0.01). However, E+D only significantly increased endometrial thickness (P<0.01) and no significant improvements were observed in the RI of uterine arteries in the three groups. BYHD had a favorable therapeutic effect in patients with DOR by rebalancing hormone levels, promoting ovulation, and repairing the thin endometrium. The combination of tonifying Shen (Kidney), benefiting qi and activating blood circulation may be a promising therapeutic strategy for DOR.
