Laparoscopic cauterization of endometriosis for fertility: a controlled study.

Ninety infertility patients with moderate endometriosis were randomized between laparoscopic electrocautery and 6 months of danazol therapy and studied for 7 months after treatment. Twenty of the 45 patients undergoing electrocautery conceived (44%) during the follow-up interval. Forty-one of the 45 patients in the danazol group completed the course of therapy, and 16 of those conceived (39%) during the same follow-up interval. There was no statistical difference between the two groups (P less than 0.53). No patients in the electrocautery group experienced complications. This demonstrates that electrocautery is safe and effective in the treatment of moderate endometriosis.
