Preimplantation genetic diagnosis
Preimplantation genetic diagnosis (PGD) plays an important role in the implementation of the surrogate motherhood programme. This method has been invented for identifying chromosome diseases at the early stages of embryo development, such as hemophilia, Down’s syndrome, etc., and for preventing congenital abnormalities. PGD allows diagnosis and assessment of the condition of the embryo even before the transfer into the uterus, which significantly increases the chance of a successful implantation of the embryo from the first attempt.
If you are worried that the procedure may harm the fetus, then we hasten to reassure that the procedure has no effect on the further development of the fetus. The fact is that at the time of the procedure the embryo consists of identical cells which are easily interchangeable with a further division. Tissues or organs, which could be potentially damaged, do not even exist yet.
Thus, this procedure does not harm embryos, and the high pregnancy rate in cycles of treatment using PGD proves that.
A PGD procedure has its advantages:
- The ability to select and transfer only healthy embryos, with no chromosomal abnormalities,into the uterus.
- Reduces the risk of giving birth to a child with certain genetic defects.
- Reduces the risk of miscarriage.
- Reduces the risk of multiple pregnancies, because it is possible to transfer one healthy embryo.
- Increases the chances of a successful implantation (approximately by 10%).
- Increases the chances of labour without complications (by about 15-20%).
