Investigating outcomes of transferring mosaic embryos in infertility treatment

A Prospective Study of a Mosaic Embryo Transfer

Not applicable Interventional Colorado Center for Reproductive Medicine · NCT04472156

This study is trying to see if transferring mosaic embryos, which have both normal and abnormal cells, can help women aged 18-45 who are undergoing IVF have successful pregnancies and live births.

What this trial studies

This research investigates the clinical outcomes of transferring mosaic embryos, which contain both normal and abnormal cells, that have been screened using preimplantation genetic testing (PGT). The study involves women aged 18-45 who have undergone an IVF cycle at the Colorado Center for Reproductive Medicine and have a mosaic embryo available for transfer. The aim is to evaluate implantation and live birth rates to determine if these embryos should be routinely offered for transfer, despite current practices that typically exclude them. The study seeks to enhance understanding of the relationship between embryonic mosaicism and successful pregnancies.

Who should consider this trial

Good fit: Ideal candidates are infertile women aged 18-45 who have completed an IVF cycle with PGT and have a mosaic embryo available for transfer.

Not a fit: Patients who do not meet the clinical requirements for embryo transfer or those desiring more than a single embryo transfer may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide new options for infertile patients by demonstrating that mosaic embryos can lead to healthy pregnancies.

How similar studies have performed: Previous studies have shown that mosaic embryos can result in healthy live births, suggesting potential for success in this approach.
