Letrozole with IUI versus natural cycle IUI
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You and your partner have been told your infertility is “unexplained” or mild male-factor infertility.
- Your fallopian tubes must be open (tubal patency) on at least one side, based on the clinic’s usual tests.
- Your partner’s semen analysis must show at least 5 million total moving sperm (TMSC).
- Your menstrual cycles must be regular (not irregular).
- You should not have PCOS or other hormone (endocrine) disorders that affect cycles.

This study compares two common lab procedures—ICSI and conventional IVF—to see which works better for couples with unexplained infertility. If you are starting your first IVF cycle and meet certain health criteria, you may be able to join.
This study tests whether intrauterine insemination (IUI), a simple procedure where sperm is placed directly into the uterus, improves the chance of a successful pregnancy for couples who have had at least one unexplained miscarriage. It aims to help couples who are trying again within a year of their loss.
This trial tests whether taking progesterone after a type of fertility treatment called IUI can improve success rates. The study focuses on people who are using a drug called letrozole to stimulate the ovaries.
This trial tests if combining two fertility medications (letrozole and clomiphene citrate) works better than using letrozole alone to help women with ovulation problems release an egg. The goal is to find a more effective treatment for women trying to conceive.
This trial compares two ways to prepare the uterus for a frozen embryo transfer: using the hormone letrozole or a standard artificial cycle. The goal is to see which approach works better for people with irregular periods.
This study tests if a medicine called letrozole can help prepare the lining of the womb for a frozen embryo transfer. It may be an option for women under 40 who have had limited previous IVF cycles.
