Hormone treatment to improve frozen embryo transfer success
Treatments studied
Part of Women’s health & pregnancy clinical trials.
This trial tests whether giving a medication called a GnRH agonist (which affects hormones) before a frozen embryo transfer can improve the chances of pregnancy in women with infertility. It aims to see if this treatment helps the uterus accept the embryo better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 20 and 39 years old.
- You need at least one good-quality embryo (graded 3BB or higher) available for transfer.
- Your uterine lining must be at least 7 mm thick on the day you start progesterone.
- Your body mass index (BMI) should be between 18 and 35.
- This must be your first or second frozen embryo transfer (FET) cycle.
- You should not have had 3 or more failed embryo transfers, severe endometriosis, uterine abnormalities, or a history of 2 or more miscarriages.

This trial tests whether giving a hormone-lowering drug for a longer time before frozen embryo transfer, plus adding a hormone pill (letrozole), improves success for people with adenomyosis. It aims to help those with this womb condition have a better chance of a successful pregnancy.
This trial studies whether giving a GnRH “downshifting” shot before transferring a frozen embryo can improve pregnancy outcomes for people with endometriosis or adenomyosis. It may help by changing hormone activity before the transfer.
This study tests whether using a hormone medication (GnRH agonist) before a frozen embryo transfer helps women with adenomyosis. If you have adenomyosis and are planning a frozen embryo transfer, this trial will help compare results with or without the pre-treatment.
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.
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 study compares two different ways to prepare the womb for transferring a frozen embryo, to see which approach works better. It aims to find the most effective method to help you have a successful pregnancy.
