Seventy-nine cases of ovarian endometrioma were treated via the laparoscope. The 
surgical technique gradually evolved from drainage alone to fulguration and 
finally to excision of the endometrioma cyst wall. Indications for laparoscopy 
were infertility (35 cases), pain (33), hypermenorrhea (5) and pelvic mass (4); 
the condition was an incidental finding in 2 cases. There were no intraoperative 
or postoperative complications. The long-term results, especially the fertility 
outcome, have been promising: 12 of 20 women (60%) achieved a term pregnancy 
following a laparoscopic endometrioma procedure alone. Of the eight women with 
endometriomas who did not conceive, six had well-documented male factor 
infertility.
