Results: Among all doses, the CTX 100 mg/kg + Bu 20 mg/kg regimen reliably induced POF within 3 weeks post-administration, as demonstrated by three key criteria: (1) persistent follicular decline in ovarian reserve (2) endocrine disruption (significantly elevated FSH and suppressed AMH/E2 levels and (3) sustained ovarian dysfunction throughout the 3-week post-induction observation period (until week 6 post-injection). This evidence concerns the gene BRD2 and ovarian dysfunction.
