aTo obtain serum anti-Müllerian hormone (AMH) in ng/mL, divide by 7.14.
bKruskal–Wallis test followed by Dunn’s multiple comparison test (Controls vs Unilateral vs Bilateral). In each age subgroup, a different letter indicates that there is a significant difference when comparing Controls vs Unilateral vs Bilateral (P < 0.05).
