Micronized progesterone for frozen embryo transfers
Treatments studied
Part of Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18–43 after your own (autologous) IVF cycle, or under 50 after an egg donation cycle.
- Your cycle will use hormone replacement (hormones to prepare the uterus) and involve a blastocyst embryo transfer.
- Your BMI is between 18 and 30 kg/m².
- You have no major uterine conditions like fibroids/polyp growth inside the uterus or known genital tract structure differences.
- You can attend the clinic for blood tests, visits, and to pick up study medication.
- You are not pregnant or breastfeeding, and you can safely take hormone treatment (no contraindications).

This study compares two forms of vaginal progesterone used to prepare the uterus for a frozen embryo transfer (FET). It may be a good option if you are already prescribed one of these progesterone regimens and are planning a single embryo transfer.
This trial tests whether a 2-3 month hormone treatment before a frozen embryo transfer improves pregnancy success in women with deep endometriosis. It may help your body prepare better for the embryo.
This trial compares two ways of timing progesterone support for frozen embryo transfer in women with regular cycles. It aims to find which approach gives the best chance of pregnancy.
This study looks at how progesterone levels affect the success of frozen embryo transfers. It compares different vaginal progesterone products to see if levels matter for pregnancy outcomes.
This study tests whether giving extra progesterone injections under the skin helps pregnancies succeed after IVF when progesterone levels are low. You'd already be pregnant from IVF and have a low progesterone result to qualify.
This study looks at how progesterone levels on the day of embryo transfer affect the chance of pregnancy in frozen embryo transfer (FET) cycles. It aims to find if certain levels can improve outcomes for patients.
