Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

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).
