Abstract
OBJECTIVE: To investigate the follicular response to controlled ovarian hyperstimulation (COH) in IVF-ET cycles after laparoscopic ovarian cystectomy for large endometriomas. PATIENTS AND METHODS: In the set of a retrospective controlled study, the medical records of 113 infertile women who underwent IVF-ET cycles after laparoscopic surgery were reviewed. The study group (A) consisted of 63 patients with severe pelvic endometriosis and endometrioma excision. The control group (B) consisted of 50 infertile patients with mild or minimal endometriosis. Interventions were laparoscopic ovarian cystectomy in the study group, and COH in both groups. RESULTS: Groups A and B were not different in terms of epidemiologic data. The total numbers of recruited follicles (9.1+/-3.3 vs 10.6+/-4.2; P = 0.001), mature follicles (> or =16 mm) (4.2+/-1.7 vs 4.8+/-2.2; P = 0.04), mature oocytes retrieved (5.8+/-3.8 vs 7.4+/-4.6; P = 0.02), and fertilization rate (48.9+/-34.9 vs 61.8+/-32.1%; P = 0.02) observed in group A were lower than those observed in group B, respectively. While the mean number of rFSH ampoules (75 IU) was increased in group A (38.1+/-20.4) compared to group B (29.3+/-16.4; P = 0.004), cumulative pregnancy rates were similar in both groups (27.5+/-8.8% vs 37.2+/-10.6%; P = 0.37). DISCUSSION AND CONCLUSIONS: Ovarian response was reduced during IVF-ET cycles in patients with history of severe endometriosis and laparoscopic excision of endometriomas compared to women with mild or minimal endometriosis without ovarian surgery.
