Comparing two methods of timing a frozen embryo transfer
Part of Women’s health & pregnancy clinical trials.
This trial compares a new method to time a frozen embryo transfer (using a test called ERA) with the standard method. The goal is to find the best time to transfer a high-quality embryo in women who have had multiple failed IVF attempts (recurrent implantation failure).
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have had repeated IVF cycles without a successful pregnancy (recurrent implantation failure).
- You are under 40 years old.
- Your body mass index (BMI) is between 18.5 and just under 30.
- You have at least one high-quality frozen embryo (Grade BB or better) and plan to transfer just one.
- You do NOT have a history of recurrent miscarriages (3 or more), chromosomal abnormalities, or certain uterine or medical conditions.

Other trials that look related to this one.
This study tests whether checking the timing of the uterine lining (endometrium) before transferring an embryo can help women who have had multiple failed embryo transfers. It aims to improve the chance of a successful pregnancy for women under 35 with no known cause for their infertility.
This study tests if a blood test measuring tiny molecules (miRNAs) can predict when the uterus is most ready for an embryo. It aims to improve IVF success in women with unexplained repeated implantation failure.
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 compares two different timings for a lab procedure called assisted hatching (making a small opening in the embryo's outer shell) to see if one helps more embryos implant. You may be eligible if you're doing IVF with a frozen embryo transfer of a single screened embryo.
This trial compares transferring a frozen embryo right away versus waiting for a later cycle. It is designed for women with regular or irregular menstrual cycles who have at least one good-quality frozen embryo.
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.
