Primary Outcome Measures:
  • occurrence of ovulation and midcycle endometrial thickness (mm).

Secondary Outcome Measures:

Enrollment: 260
Study Start Date: August 2006
Study Completion Date: March 2009
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Letrozole
2.5 mg letrozole oral tablets daily from day 3 of the menses for 5 days up to 6 cycles
Drug: Letrozole
2.5 mg letrozole oral tablets daily from day 3 of the menses for 5 days up to 6 cycles
Active Comparator: Laparoscopic ovarian diathermy (LOD)
Three-puncture technique. Each ovary was cauterized at four points, each for 4 seconds at 40 W for a depth of 4 mm with a mixed current, using an monopolar electrosurgical needle.
Procedure: Laparoscopic ovarian diathermy (LOD)
Three-puncture technique. Each ovary was cauterized at four points, each for 4 seconds at 40 W for a depth of 4 mm with a mixed current, using an monopolar electrosurgical needle.

Detailed Description:
In the letrozole group, withdrawal bleeding was achieved using 10 mg of dydrogesterone tablets for 10 days before stimulation, then 2.5 mg of letrozole oral tablets (Femara; Novartis Pharma Services, Switzerland) daily from day 3 of the menses for 5 days up to six cycles. All patients in the control group underwent laparoscopic ovarian diathermy, then followed up for 6 months.
