Natural embryo transfer with or without progesterone support
Treatments studied
Part of Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 40 years old
- You have regular, predictable ovulatory cycles
- You have at least one euploid embryo available after genetic testing (PGT-A) on day 5 or day 6
- Your clinic can detect ovulation by a progesterone (P4) rise after an LH surge (P4 rise > 1.0 ng/mL)
- Your progesterone (P4) level is at least 5 ng/mL on day 4 after ovulation

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 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 compares two types of natural cycle preparation for frozen embryo transfers to see which leads to more pregnancies. It may be a good fit if you are using your own eggs, have regular cycles, and are planning a frozen embryo transfer.
This trial is for women aged 35–40 doing IVF. It compares genetic testing of embryos before transfer to standard care, to see if it improves pregnancy success.
This study is testing whether starting a frozen embryo transfer during your natural cycle (after ovulation) is more convenient than the usual schedule. You will take progesterone (400 mg twice a day) and have one embryo transferred. It is for people using donor eggs who have regular cycles.
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.
