Have you ever wondered, can I choose the sex of the baby? This is actually possible. A PGT-A genetic study gives you the choice of whether you want to have a girl or a boy. Below we share a little more information about this analysis so that you know it.
Also known as the preimplantation genetic study for aneuploids, it helps to identify possible alterations that may be found in the chromosomes of an embryo.
This minimizes the possibility of having a baby with the pathologies that we will explain later.
An embryo that has a total of 46 chromosomes (23 pairs, from the father and the mother) is considered “euploid”. 22 of these chromosomes are called somatic, and 23 is the sexual one. The one who brings “sex” to a baby, X or Y.
23 of the chromosomes come from the sperm. This can give an X if it is going to be a girl or Y if it is going to be a boy.
An “aneuploid” embryo is one that does not have 23 pairs of chromosomes. In this case there is a duplication (more than common) or a deletion (less than common) in one of the chromosomes, which generates a pathology in the embryo.
The most common case is trisomy 21 which causes Down syndrome. Other examples are Patau Syndrome, Edwards Syndrome.
