Immediate vs. later frozen embryo transfer in women with regular or irregular cycles
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are eligible for a frozen embryo transfer right after a fresh cycle or after freezing all embryos.
- You have either irregular cycles (longer than 35 days) or regular cycles (21–35 days).
- You have at least one frozen day 5 or 6 embryo with a quality score of 3BB or better.
- You do not have uterine abnormalities, blocked fallopian tubes, or fibroids/polyps inside the uterus.
- You are not allergic to or cannot take standard fertility medications.
- You are not using donor eggs, and the fresh cycle did not involve genetic testing or extracting sperm from the testicle.

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).
This study tests a new, quicker way to freeze embryos (blastocysts) that are ready for use in future pregnancy attempts. It may help preserve embryo quality and improve success rates for people using donor eggs.
This trial compares two methods of warming frozen embryos before transfer—one with a single step and one with multiple steps. It aims to see which approach leads to better pregnancy outcomes for women using their own frozen embryos.
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 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 study looks at how directly warming a frozen embryo (without extra laboratory steps) affects pregnancy outcomes when transferring a single embryo. If you are undergoing a frozen embryo transfer with a good-quality embryo, this trial may help improve your chances of success.
