Endometrioma and oocyte retrieval-induced pelvic abscess: a clinical concern or an exceptional complication?

The authors evaluated the risk of developing a pelvic abscess in a series of 214 in vitro fertilization cycles that were performed in women with endometriomas. This complication was never recorded, indicating that its risk is very low (0.0; 95% confidence interval, 0.0-1.7%).
