Corpus Luteum's effect on frozen embryo transfer pregnancies
Part of Women’s health & pregnancy clinical trials.
This study looks at whether having a corpus luteum (the structure left after an egg is released) affects pregnancy outcomes in frozen embryo transfer cycles. It aims to help doctors choose the best way to prepare the body for embryo transfer.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 37 when your eggs were taken, and under 41 at the time of embryo transfer.
- You have regular periods (every 24 to 35 days).
- You have your own frozen blastocysts (embryos at a certain stage) to use.
- You are planning to transfer only one embryo.
- You have not had 3 or more miscarriages or 3 or more failed embryo transfers.
- You do not have certain health conditions like PCOS, diabetes, high blood pressure, heart disease, lupus, or antiphospholipid syndrome, and you are not on blood thinners or anticoagulants.

Other trials that look related to this one.
This trial compares two ways to prepare the uterus for a frozen embryo transfer: using the hormone letrozole or a standard artificial cycle. The goal is to see which approach works better for people with irregular periods.
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.
This Phase 1 study compares pregnancy outcomes, especially live birth, when using a natural-cycle frozen embryo transfer with an embryo that is genetically euploid (normal chromosome number) versus doing transfers without luteal (progesterone) phase support. It may help determine whether adding progesterone around ovulation improves the chance of a live birth.
This study tests if a medicine called letrozole can help prepare the lining of the womb for a frozen embryo transfer. It may be an option for women under 40 who have had limited previous IVF 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.
