Official Title: The Predictive Value of Serum Inhibin B/FSH Ratio in Estimating Pathology Results in Patients Undergoing Micro-TESE Due to Azoospermia

Brief Summary: This retrospective observational study evaluated the diagnostic and predictive value of serum Inhibin B (INHB), follicle-stimulating hormone (FSH), and the INHB/FSH ratio in differentiating histopathological subtypes of non-obstructive azoospermia (NOA) in men undergoing microdissection testicular sperm extraction (micro-TESE).Seventy-three patients treated at a single tertiary referral center between January 2023 and September 2025 were included.Hormonal parameters were assessed preoperatively, and…
