 Randomization was done according to a computer generated random numerical table into two equal groups. Treatment allocation was concealed by using sequentially numbered opaque sealed envelopes. Envelopes were opened consecutively by a third person study nurse, who assigned patients to the extended Clomiphene Citrate group Group A or LOD group Group B. Once allocated, the treatment was revealed to both the investigator and the patient. Group A n 68 assigned to receive100 mg of clomiphene citrate Clomid; Hoechst Marion Russel, Cairo, Egypt daily starting on day 3 of spontaneous or progestin induced cycle for 10 days. Group B n 68 underwent LOD. Laparoscopy was performed under general anesthesia, using three-puncture technique. Each ovary was cauterized perpendicular to its antimesenteric border at four points, each for 4 seconds at 40 W with a mixed current, using a monopolar electrosurgical needle Karl Storz, ND, Germany. Each puncture was about 4 mm in diameter and 6-8 mm in depth. The ovary was cooled by irrigation with normal saline solution. Any, intraoperative or postoperative complication was reported. The follow-up was started from the next cycle after ovarian drilling up to 6 months.
