Mosaic embryos: Navigating technical uncertainties in assessing embryo potential

Abstract

Since the 1990s, preimplantation tests within in vitro fertilization have promised to enhance the selection of embryos for uterine implantation. However, alongside ethical controversies, these diagnostic techniques often identify a high rate of mosaic embryos—those containing a mix of cells deemed normal and abnormal—creating one of the largest technical challenges related to the testing. These cases raise dilemmas for professionals in assisted reproduction and, more intensely, create challenges for individuals whose embryos are identified as mosaic. This article examines the experiences of a woman who decides to implant a mosaic embryo, focusing on her strategies for managing technical uncertainties and evaluating the embryo's potential. It highlights the essential role that online forums play in this process and examines how users utilize these platforms to gain insights and navigate the complex decisions involved with new biomedical technologies.
