PGT full form in medical term is Preimplantation Genetic Testing. It is basically a medical procedure that can help couples who are trying to conceive a baby through in vitro fertilization (IVF). With IVF, the woman’s eggs are fertilized with the man’s sperm in a laboratory, and the resulting embryos are then transferred into the woman’s uterus. PGT is a way to test these embryos for any genetic abnormalities before they are implanted, which can help increase the chances of a successful pregnancy. When a couple undergoes PGT, a few cells are taken from the embryo and tested for genetic conditions. This is usually done on the third day after fertilization when the embryo has divided into about eight cells.
Based on the results of the genetic testing, the couple can choose which embryos to transfer into the woman’s uterus. This can help to increase the chances of a healthy pregnancy and reduce the risk of passing on genetic diseases to the child. It’s important to note that PGT is not mandatory, and some couples may choose not to have it done. However, for couples who are at risk of passing on genetic disorders to their child or who have had multiple failed IVF attempts, PGT can be a valuable tool in their fertility journey.
