What Does It Mean When Your Embryo Is a Mosaic?
Mosaic embryos are those that have a mix of normal and abnormal cells, making their genetic makeup unclear. Specifically, a mosaic embryo refers to an embryo that has a mix of normal and abnormal cells. This condition arises during early development when some cells in the embryo have the correct number of chromosomes (euploid), while others have an abnormal number of chromosomes (aneuploid).
What Causes a Mosaic Embryo?
Chromosomal abnormalities can occur due to errors during cell division, and mosaic embryos may be a result of these errors. Mosaicism can vary in severity, and the proportion of normal and abnormal cells can differ in each case. Preimplantation genetic testing (PGT) is a process that allows for the identification of genetic abnormalities in embryos prior to their transfer in IVF treatment.
Is It Safe To Transfer a Mosaic Embryo?
When it comes to mosaic embryos, there are different options available to couples depending on their individual circumstances and preferences. One option is to transfer the mosaic embryo as is, but this carries a higher risk of implantation failure, miscarriage, or birth defects. Another option is to discard the mosaic embryo and proceed with transferring a non-mosaic embryo or pursuing another round of IVF.
There is also the option of performing additional testing, such as a biopsy or retesting of the mosaic embryo, to gain more information about its genetic makeup and potential viability. This can help couples make more informed decisions about whether or not they want to transfer the mosaic embryo.
