Embryo transfer using aneuploid or mosaic embryos during pregnancy
Part of Genetic & congenital, Women’s health & pregnancy clinical trials.
This trial looks at pregnancy and baby outcomes when embryos that have chromosome differences (aneuploidy or mosaic embryos) are transferred, especially when no other embryos are available. It may help people understand the risks and expected outcomes in situations where options are limited.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have embryos that are aneuploid or mosaic (chromosomes not in the usual number, either fully or in some cells)
- There are no other embryos that could be used for transfer instead
- You are willing and able to travel to Stanford for the treatment
- You can read and speak English well enough for study steps and consent
- You live in the United States
- Your embryos do not have triploidy (an extra full set of chromosomes)

This registry is collecting information from people who plan to transfer an embryo that is not genetically normal (non-euploid) at a fertility clinic in The Prelude Network. It will help doctors learn more about outcomes with these embryos.
This study follows people who have infertility and, after IVF testing (PGT), have a “mosaic” embryo result. It looks at transferring one embryo to see how this approach works when mosaic changes are present.
This study aims to check if embryos previously considered too abnormal (with three or more chromosomal issues) might actually be usable for transfer. It may offer new options for patients who have only these types of embryos available.
This trial is for women aged 35–40 doing IVF. It compares genetic testing of embryos before transfer to standard care, to see if it improves pregnancy success.
This trial tests whether checking embryos for extra or missing chromosomes (aneuploidy) before transfer improves IVF success for women aged 37-41. You may be eligible if you have a partner or are using donor sperm and have normal ovarian reserve.
This trial studies how the immune system in the uterus may impact whether a genetically normal frozen embryo implants successfully. It aims to help improve success rates for women undergoing IVF.
