hCG use in frozen embryo transfer
Treatments studied
Part of Women’s health & pregnancy clinical trials.
This study tests whether giving hCG before transferring a thawed embryo can improve success. It is for women who have at least one frozen embryo of good quality and are planning a frozen embryo transfer.

This trial tests a medication called human menopausal gonadotropin to help women undergoing IVF achieve a live birth. It focuses on the cumulative success rate after freezing and later transferring embryos.
This study compares different methods for transferring frozen embryos into the uterus during IVF. It aims to find the best technique to improve pregnancy chances.
This trial tests whether a hormone called HCG (human chorionic gonadotropin) improves pregnancy success when transferring a frozen embryo back into the uterus during a natural cycle. The study focuses on women with higher body weight, as they may respond differently to fertility treatments.
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.
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 checks if taking extra hormones after a frozen embryo transfer (called luteal support) is needed when using your natural cycle. It may help improve pregnancy chances.
