Endometrioma undergoing laparoscopic ovarian cystectomy: its influence on the outcome of in vitro fertilization and embryo transfer (IVF–ET)

Abstract

To evaluate the effect of laparoscopic ovarian cystectomy for endometrioma on the clinical outcome of IVF treatment. Patients who received IVF treatment were retrospectively classified into two groups. Group 1 included 95 patients who received IVF due to tubal occlusion. Group 2 included 127 patients who had received laparoscopic ovarian cystectomy for endometrioma(s) followed by IVF treatment. Clinical outcomes of IVF treatment were compared between two groups. More oocytes were harvested per retrieval in Group 1 than Group 2 (p < 0.05). The fertilization rate was higher in Group 1 than Group 2 (p < 0.05). Although the implantation rate was higher in Group 2 (p < 0.05), the clinical pregnancy rate revealed no statistically significant difference between the two groups. Women who received ovarian cystectomy for endometriomas have fewer oocytes harvested during IVF treatment. However, their chance of pregnancy was comparable to patients with tubal problems who underwent IVF treatment.
