Can you choose the sex of your baby?
"Can you choose the sex of my baby?", the short answer is yes, you can. However, what the IVF clinic cannot do is change the sex of an embryo.
After the eggs from the donor are fertilized, they will be incubated for five days where they will grow to become embryos. Once the embryos are formed, the IVF physician will perform pre-implantation genetic testing (PGT). The results of the PGT test tell us a few things. The first being, whether or not the embryo is genetically normal. Meaning, does the embryo have 23 chromosomes? From these chromosomes, we can tell if the embryo will be male or female.
Once we find out the sex of the embryo, we can choose which embryo to transfer, based on your preference. But, as mentioned earlier we cannot change the sex of the embryo. So each embryo has a 50-50 chance of being a boy or girl. There is a chance depending on how many eggs you have to fertilize that they could all turn out to be the same sex.
