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.

Other trials that look related to this one.
This study compares two ways to pick the best single embryo for transfer during IVF: using a new non-invasive (without touching the embryo) test versus the standard grading by how the embryo looks under a microscope. It aims to improve the chance of a successful pregnancy.
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 looks at whether checking the fluid around embryos for genetic problems can help predict success in IVF. It may help doctors choose the best embryo to transfer.
This trial compares transferring a fresh embryo on day 2 versus day 3 after fertilization to see which timing offers a higher chance of a live birth for women with low ovarian reserve. If you are 35 or older and have low egg supply, this study might help you understand the best time to transfer your embryo.
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 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).
