Animal Models and Experimental Medicine, EarlyView.Brefeldin A (BFA) significantly inhibits oocyte release and induces apoptosis in ovarian granulosa cells by disrupting follicular development. It downregulates proliferation‐associated genes, reduces SIRT1/SIRT6 proteins, and upregulates cell cycle inhibitors P21 and P16. Additionally, BFA impairs estrogen synthesis and affects ovarian function through
