This retrospective study was performed to compare the success of ovulation induction using letrozole versus gonadotropins in women at least 38 years of age, with normal ovarian reserve. Pregnancy and clinical pregnancy rates (PR) were statistically higher with gonadotropin than with letrozole stimulation. |
