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 Phase 3 study tests whether adding micronized progesterone during frozen embryo transfer cycles helps support embryo implantation and pregnancy. You may benefit if your care team is already preparing the uterus with hormone therapy for a blastocyst transfer.
This trial tests whether a hormone called GnRH can help support the lining of the uterus after IVF, ICSI, or frozen embryo (FET) embryo transfer. It may be offered around the time of embryo transfer to improve the chances of a successful implantation.
This Phase 3 study tests whether taking an oral progesterone-like medicine (dydrogesterone) during the “luteal phase” after a natural-cycle frozen embryo transfer can improve support for implantation. It may help couples who are using their own embryos in a natural (hormone-sparing) cycle after thawing.
This study tests if a combination of two hormone drugs (follitropin alfa/lutropin alfa) works as well as another drug (hMG) for Japanese women with low LH and FSH levels who are doing in vitro fertilization (IVF). The goal is to help them produce eggs for pregnancy.
This study tests whether adding support in the period after ovulation (the “luteal phase”) helps people who are starting IUI (intrauterine insemination) because their infertility is unexplained. It’s designed to see if the added care improves chances when mild ovarian stimulation is used.
