Does frozen embryo transfer need luteal support?
Treatments studied
Part of Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 40 years old when your embryos were frozen
- You have at least one good quality frozen blastocyst (an early-stage embryo)
- You plan to transfer just one embryo
- You have had fewer than 3 failed embryo transfers in the past
- Your menstrual cycle is usually 21 to 35 days long
- Your body mass index (BMI) is between 18 and 35

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 explores how natural uterine contractions affect pregnancy success in women using hormone therapy for frozen embryo transfer. It may help doctors understand if uterine activity influences implantation.
This study looks at how different ways of preparing the uterus for a frozen embryo transfer affect the natural wavelike movements of the womb lining (endometrial peristalsis). It may help doctors choose the best protocol for you.
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 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 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.
