Progesterone Levels and Frozen Embryo Transfer Success
Treatments studied
Part of Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 51 years old.
- You are planning a frozen embryo transfer with vaginal progesterone (like Endometrin) plus progesterone-in-oil shots every 3 days.
- You will transfer one embryo that has been tested and found to have the correct number of chromosomes (euploid).
- You do not have a uterine abnormality that hasn't been surgically corrected.
- You are not currently breastfeeding, pregnant, or have a medical condition that prevents pregnancy.
- You have not taken part in an experimental drug study in the past 60 days.

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.
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 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 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 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 measures changes in your blood immune markers during frozen embryo transfer when the embryo is chromosomally normal. It may help clinics understand what blood immune patterns relate to successful pregnancy in natural or hormone-prepared cycles.
