Impact of unilateral versus bilateral ovarian endometriotic cystectomy on ovarian reserve: a systematic review and meta-analysis.

Ovarian endometrioma is a frequent manifestation of endometriosis in women of reproductive age. Several issues related to its space occupying effects, local reactions and surgical removal continue to be actively debated today. The impact of ovarian endometrioma per se on ovarian reserve is still controversial and the effect of ovarian surgery is still actively discussed. Furthermore, the optimal biomarker of ovarian reserve estimation in women with ovarian endometrioma is still under examination. Additionally, there is no consistent agreement on the effect of endometrioma bilaterality on ovarian reserve.
