All of us, even if we are healthy, can be carriers of DNA alterations known as genetic mutations. These mutations do not affect our health, but if both members of a couple are carriers of the same mutation, there is an increased risk of having a child with a genetic disease.
At HC Fertility we offer our patients the possibility of undergoing a genetic compatibility test, which allows us to detect hereditary diseases that could be transmitted to the offspring.
The test is based on a simple blood sample taken from both members of the couple, which is analysed by a specialised genetics laboratory. Once the results are available, genetic matching is carried out. This test compares the genetic information of both partners to verify that they are not carriers of the same mutation. If they are not, the risk of transmitting the disease to the future baby is ruled out.
In the event that both are carriers of the same mutation for a serious disease, a Pre-Implantation Genetic Test (PGT) can be performed on embryos generated by In Vitro Fertilisation (IVF) , in order to identify those free of the disease.
Genetic matching can be performed both in couples who will use their own gametes for an IVF cycle, as well as in those who resort to oocyte and/or sperm donation. In these cases, the genetic information of the donor is compared with that of the member of the couple who will provide his/her gametes to ensure compatibility.
