Ovarian reserve evaluation by anti-mullerian hormone in women undergoing laparoscopic cystectomy of endometrioma.

OBJECTIVE To study the serial changes of serum AMH to determine ovarian reserve recovery after laparoscopic cystectomy of endometrioma. MATERIAL AND METHOD Forty-three endometrioma patients who underwent laparoscopic cystectomy of endometrioma were tested for levels of serum AMH at preoperation, 1 week, and 3 months postoperation. RESULTS Median serum AMH was 2.11 ng/mL (range = 0.22 to 9.24 ng/mL) before surgery. This level also reduced at first week postoperation (p < 0.01) but did not reach a significant difference between the first week and the third month (1.02 ng/mL and 1.06 ng/mL, respectively). The recovery rate of AMH level in unilateral endometrioma was higher than bilateral endometrioma (32.4% vs. -3.6%, p = 0.02). CONCLUSION Ovarian reserve was decreased after laparoscopic cystectomy of endometrioma and did not significantly restore after three months of postoperation. The recovery of ovarian reserve after unilateral endometriotic cystectomy was faster than that after bilateral endometriotic cystectomy.
