Mosaicism and IVF Success
April 16, 2018
(Medscape) – If we knew the genetic composition of the embryo before the transfer, we could avoid the transfer of unhealthy embryos and could expect improved clinical outcomes. This concept was the basis for the development of preimplantation genetic screening (PGS) of embryos. The technology has improved significantly over the years, but still a large proportion of embryos diagnosed as euploid do not implant. On the other hand, some of the embryos that tested abnormal do implant and result in healthy deliveries. A recent study evaluated IVF outcomes after the transfer of mosaic embryos.
