GnRH Hormone for IVF Embryo Support
Treatments studied
Part of Women’s health & pregnancy clinical trials.
This study tests whether a hormone called GnRH can improve success rates during IVF (in vitro fertilization) by supporting the embryo after transfer. If you're having IVF for the first to third time and your doctor is considering different support methods, this trial may explore options for you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a woman between 18 and 45 years old
- You are undergoing IVF for ovulation problems, blocked tubes, low egg reserve, or male partner infertility
- This is your first, second, or third IVF cycle
- Your BMI is between 19 and 35 (neither too low nor too high)
- You are planning a fresh embryo transfer (not frozen), and your embryos have not had genetic testing (PGT)
- You do not have a history of multiple failed embryo transfers, moderate-to-severe endometriosis, or blocked fallopian tubes

This trial tests whether giving a medication called a GnRH agonist during the luteal phase (the time after egg retrieval) can help with IVF success. It is for people who are using a specific medication protocol (recombinant FSH with an antagonist) and have certain hormone levels.
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 trial tests whether adding a GnRH agonist medication before a frozen embryo transfer can improve success rates. It may help women undergoing their first or second frozen embryo transfer who have good quality embryos.
This trial tests whether adding a hormone (r-hLH) to standard ovarian stimulation medicine helps women aged 35 to 40 produce more eggs during IVF. It may be a good option if you have lower ovarian reserve and are starting your first or second IVF cycle.
This study compares two types of hormonal support—a GnRH agonist (given as a nasal spray) versus progesterone—after a frozen embryo transfer in a natural menstrual cycle. It aims to see which helps more women achieve pregnancy.
This study compares two ways to prepare the ovaries for egg retrieval before IVF: using a progestin hormone or a GnRH antagonist. The goal is to see which method leads to more successful embryo transfers.
