Laparoscopic cystectomy for large endometriomas did not significantly decrease oocyte or embryo numbers compared to patients with endometriosis without endometriomas or tubal infertility.

Abstract

BACKGROUND: Ovarian response during IVF cycles after laparoscopic ovarian cystectomy for endometriotic cysts >3 cm is controversial. A retrospective study was designed to study this problem. METHODS: At laparoscopy, endometriomas >3 cm were treated by ovarian cystectomy, whilst adhesions and peritoneal endometriosis were treated using conventional techniques. Ovarian stimulation was achieved with clomiphene and gonadotrophins or with gonadotrophins after a desensitization with gonadotrophin-releasing hormone agonists. Three groups of patients were retrospectively selected from an IVF-embryo transfer database: patients who underwent laparoscopic ovarian cystectomy for an endometrioma >3 cm (Group A, n = 41), patients with endometriosis without ovarian endometrioma (Group B, n = 139) and patients with tubal infertility (Group C, n = 59). RESULTS: The groups did not differ in age. In the first IVF cycle, the mean (+/- SD) numbers of oocytes and of embryos were 9.4 +/- 6.2 and 4.7 +/- 3.6 respectively in group A and 11.6 +/- 7.5 and 5.1 +/- 4.9 in group B (not significant). The results did not differ in cycles 2 and 3 or when compared according to age. No difference was found when comparing patients with endometriosis and patients with tubal infertility. CONCLUSION: The number of oocytes and embryos obtained was not significantly decreased by laparoscopic cystectomy, suggesting that in experienced hands this procedure may be a valuable surgical tool for the treatment of large ovarian endometriomas. However, great care must be taken to avoid ovarian damage.
