AMH and endometriosis: As we reviewed manuscripts for this article, the following results were demonstrated: 1) the influence of endometriosis/endometrioma itself on ovarian reserve remains controversial, 2) cystectomy for endometriomas tends to reduce AMH levels more severely than that for other types of benign ovarian tumors, especially for bilateral or severe disease, 3) cystectomy and bipolar coagulation in endometrioma surgery could be the factors that decrease ovarian reserve.
