Association between ovarian endometrioma and ovarian reserve

Endometrioma is one of the main pathologies of endometriosis, though its pathogenesis still remains enigmatic. Ovarian reserve is defined as the number and quality of the follicles left in the ovary at any given time. The cause of infertility in women with endometriosis is multifactorial. Diminished ovarian reserve is major concern in women with endometriosis-associated infertility. Cystectomy for endometriomas could negatively impact on post-operative ovarian reserve. Some women had surgery for endometriomas suffer from poor ovarian response, which directly affects treatment results. In addition, endometriomas themselves may be a cause of diminished ovarian reserve. Destruction of normal histological structure in ovarian cortex may affect dormancy of primordial follicles. Therefore, determination of ovarian reserve may serve as an important role in the management of reproductive health of women with endometriosis. Although the knowledge on the physiology of follicular development and mechanism of maintenance of ovarian reserve are rapidly accumulating, results obtained by ovarian reserve testing after surgery should be carefully evaluated according to the time-points and selected test. Further investigation on this issue is warranted.
