Study Summary

The purpose of this study is to investigate monitoring methods during ovulation induction cycles with letrozole and their effect on pregnancy rates. Monitoring ovulation induction cycles with letrozole can be done with a variety of methods, the two most commonly utilized are home-based urinary LH kits (or ovulation predictor kits) and office-based midcycle follicular ultrasound. Letrozole coupled with follicular monitoring by ultrasound may add extra cost per cycle with no improvement in fecundability (pregnancy rates per cycle).

Primary Outcome

Percentage of women in each arm who became pregnant within the study time frame.

Interventions

  • OTHER Midcycle ultrasound + hCG injection
  • OTHER Urinary LH kits
