Comparing Day 3 vs Day 5 Embryo Transfer for IVF With Few Embryos
Part of Women’s health & pregnancy clinical trials.
This trial compares transferring embryos at the cleavage stage (day 3) versus the blastocyst stage (day 5) for women who have few embryos during an IVF cycle. It may help determine which stage gives the best chance of pregnancy for people with limited embryos.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are using your own eggs for this IVF cycle (not donor eggs).
- You have 5 or fewer fertilized eggs on the first day of embryo development.
- You are planning a fresh embryo transfer (not frozen).
- You are not planning to test all embryos genetically (PGT).
- You have had 2 or fewer previous IVF cycles and no history of 3 or more miscarriages.

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 ways to choose which single blastocyst (a 5-6 day old embryo) to transfer after IVF. It looks at a noninvasive test versus the usual method of selecting by appearance, and aims to improve the chances of a successful pregnancy.
This study compares pregnancy success when a single embryo is transferred on day 5 versus day 6 after fertilization. If you are 18 or older and having your first ICSI cycle with a single embryo transfer, you may be eligible.
This study compares transferring embryos on day 2 versus day 3 after egg collection in women over 35 with low egg numbers or low AMH levels (a hormone that reflects egg reserve). The goal is to see which timing improves pregnancy success rates in this harder-to-treat group.
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 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.
