Preimplantation genetic testing is a modern technique designed to screen healthy embryos before implantation into the uterus. The technique applies only to specific cases where there is a risk of inheritance of diseases by the parents to their future children and is considered as a complementary solution to the prenatal control.
Various diseases such as muscular dystrophy (Duchenne syndrome), Mediterranean anemia, cystic fibrosis, haemophilia and various diseases due to chromosomal abnormalities can be detected by this method and only embryos that do not show the disease can be selected for embryo transfer they.
Preimplantation genetic testing as mentioned above occurs only in specific cases where there is a detectable genetic problem and if the couple consults the geneticist, the physician and the embryologist who will deal with the particular case. It is worth mentioning that embryos receive significant stress from this invasive procedure which can not burden both the embryos themselves and their ability to implant in the uterus. Also, although the sensitivity of the method is particularly high, there is little chance that a clear diagnostic result will not be achieved.
The advantages of the method are particularly important for couples experiencing a genetic disease:
The law stipulates that prenatal genetic testing and gender selection can only be used by those couples who are at risk of transmitting to their children a serious illness. The process involves the written consent of the couple and the genetic counseling provided by the IVF.
