Abstract:
Controversy still exists concerning the optimal treatment of endometriomata in endometriosis and its related infertility. Forty-one women with endometriomata who failed to conceive during previous in vitro fertilization and embryo transfer (IVF-ET) cycles (protocol A) were readmitted for ovum pickup following transvaginal ultrasonic needle-guided aspiration of the endometriomata (protocol B). Following aspiration a significantly higher number of oocytes was recovered (P less than 0.0006); subsequently, more embryos were transferred, and significantly higher clinical pregnancy rates per cycle (P less than 0.0001) were achieved. This difference may be directly related to the reduction of extensive ectopic endometrial tissue (endometriomata) with improved ovarian response, follicular accessibility, and, most probably, improved oocyte quality.
