Progesterone levels and pregnancy in frozen embryo transfer
This study looks at whether the level of progesterone, a hormone that helps prepare the uterus for pregnancy, on the day of embryo transfer affects the chance of a successful pregnancy in women using frozen embryos. It may help doctors understand if adjusting progesterone could improve outcomes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 42 years old at the time of embryo transfer.
- Your body mass index (BMI) is less than 30.
- You are having a frozen embryo transfer using hormone replacement therapy (HRT).
- At least one good-quality embryo is being transferred.
- Your progesterone level is measured on the morning of the transfer as part of routine care.
- You do not have severe or uncontrolled thyroid problems or premature ovarian insufficiency.
- You do not have untreated severe uterine issues like large fibroids, severe endometriosis, or uterine adhesions.

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.
This study looks at how progesterone levels around the time of a frozen embryo transfer might affect the chance of a successful pregnancy. Participants will have their transfer done as usual, and researchers will measure progesterone levels to see if they relate to pregnancy outcomes.
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 tests how hormone levels (progesterone) change day to day in the lining of the uterus (endometrium) during an embryo transfer in a medicated cycle. The goal is to better time the transfer and improve success rates.
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 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.
