Objective: Premature ovarian failure (POF) leads to infertility. Numerous researchers have endeavored to enhance ovarian function through antioxidant interventions. Extract from Vitex agnus-castus (VAC) has demonstrated a protective effect. Therefore, the objective of this study was to investigate the amelioration of ovarian function following VAC treatment in a POF mouse model. Methods: In this investigation, 30 female NMRI mice were categorized into control, POF model (cyclophosphamide 120 mg/kg I.P), and experimental groups (100, 300, and 500 of VAC extract). Parameters such as body weight, vaginal smears, and follicular evaluation were examined. FSH, estradiol levels, free radicals, and the expression of the FMR1 gene were assessed. Results: The microscopic assessment revealed that POF induced morphological alterations in ovarian tissue, whereas VAC treatment significantly ameliorated ovarian tissue conditions. The follicles number exhibited a significant reduction in the POF group; however, VAC led to an increase in follicular count and elevated estradiol levels in the treatment groups. Serum FSH levels displayed an elevation in the POF group, whereas the treatment groups exhibited a substantial reduction in FSH levels compared to the POF group. The expression of the FMR1 gene demonstrated upregulation in the POF group compared to the control group (P<.05). Moreover, this expression significantly decreased in the 500-dose VAC group compared to the POF group (P<.001). ROS generation exhibited a significant increase in the POF group, which was conversely mitigated in all experimental groups. Conclusions: Our findings underscore the potential of this extract to ameliorate POF symptoms, however, further investigations are needed.
