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 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 study tests a fertility medication (human menopausal gonadotropin) to see how well it helps women have a live birth after IVF with frozen embryos. It compares the medication's effectiveness for women with infertility who are planning to freeze all embryos and transfer them later.
This study tests whether adding a hormone called HCG (human chorionic gonadotropin, the pregnancy hormone) to standard luteal support improves the chances of pregnancy after a frozen embryo transfer in women who are overweight. It may help the uterus stay ready for implantation in natural or ovulation-induced cycles.
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.
