The observation group exhibited lower FSH and LH levels while higher E2 and AMH levels compared with the control group one and three months after surgery, and the differences were statistically significant (p< 0.05), suggesting that both surgical procedures have a certain impact on ovarian reserve, and TU-LESS-E presents a smaller impact on the ovarian reserve of patients with giant ovarian cysts and huge cystic pelvic masses. Here, AMH is linked to Ovarian cyst.
