Letrozole with IUI versus natural cycle IUI

Intrauterine InseminationUnexplained Infertility

Treatments studied

Part of Women’s health & pregnancy clinical trials.

This study compares two ways of timing intrauterine insemination (IUI)—using letrozole medicine to help schedule ovulation versus using a natural (untreated) cycle. It may help couples who are trying to conceive with mild or “unexplained” infertility see which approach works better for pregnancy chances.
