    Abstract:
    Twenty patients from our in vitro fertilization program were randomly divided into two groups. Ten women underwent follicular aspiration during laparoscopy while they were under general anesthesia and 10 women had an ultrasonically guided follicular aspiration with local anesthesia. All patients had mechanical infertility, and ovulation was induced with human menopausal gonadotropins. In both groups the same aspiration system with a needle of 1.4 mm inner diameter and a continuous suction at 120 mm Hg were used. In the laparoscopy group the oocyte recovery rate was 82.5% and the fertilization rate 62.5%, with one twin pregnancy; in the ultrasound group the oocyte recovery rate was 75%, and the fertilization rate 61.9%, with a singleton pregnancy. Implications of these results are discussed.
