It is well known that heredity means the transmission of genetic traits from one generation to the next generation or from ancestors to descendants.
Examples of these characteristics are including skin color, hair, eyes color as well as a carrier or whatever disease that can be inherited from parents to their offspring.
Among the procedures of infertility treatment like ICSI, Preimplantation Genetic Testing (PGT) is needed to detect a specific genetic disease of embryos. In order to select only the healthy embryos without genetic diseases before they are transferred to the uterus.
PGT is mostly introduced to either wife or husband or both who is diagnosed or carrying hereditary diseases such as Thalassemia, red blood cell disorders, Cystic Fibrosis. This test is also useful for a couple who has experienced a child with genetic disease. The PGT can help in reducing the risk of fetal abnormalities in the future consequently!
