4 Benefits of Preimplantation Genetic Testing
What is a Preimplantation Genetic Testing?
A preimplantation genetic testing (PGT) is a comprehensive screening test performed by your reproductive specialist to identify chromosomal abnormalities and genetic diseases within embryos. This is performed to try and avoid the passing of negative traits to a child preceding an In Vitro Fertilization procedure. Eggs will be retrieved through microsurgery and later analyzed for their DNA data at a genetic laboratory. Once the evaluation of the embryos is complete – and embryos with problematic genes are extracted from the grouping – the healthy eggs are either saved for later use or implanted into the uterus.
The benefits of receiving a PGD with your reproductive specialists are very informative and far-reaching. To help you better understand how a preimplantation genetic diagnosis can help a patient in need, the most notable benefits are listed out below.
Genetic Condition Recognition
A PGD can test, assess, uncover, and identify more than 100 different genetic conditions that may be present within the parent or child. This diagnosis will allow for the recognition of serious inherited disorders so the same trait or condition won’t be passed on to a child.
A diagnosis from a PGD will also tell the parent if there are any abnormal or affected embryos before transferring them back to the mother. This will prevent affected embryos from making their way into the uterus for maturation. Unhealthy embryos will be identified for implantation for a subsequent cycle.
Often times, when a parent is a carrier of a genetic condition, or has any difficulty with natural fertility, the opportunity of having children of his or her own, may be obstructed. This allows parents or individuals to selectively have healthy biological children.
The cutting-edge technology used by reproductive specialists allows technicians to accurately diagnose genetic conditions. The equipment does not cure the conditions, however, they can prevent them.
Who Should Receive a PGT?
The information available to those planning or expecting a child through a PGT is well worth the time when weighing the levels of stress in comparison. Ease of mind is a commonly sought after goal no matter the situation – medical or not. The following are individuals who will benefit the most from a preimplantation genetic testing.
- Carries of genetic disorders resulting from sex-linked conditions in the X or Y chromosome (i.e. hemophilia or male infertility).
- Carriers of genetic disorders resulting from a gene disorder (i.e. sickle cell anemia or cystic fibrosis).
- Genetic carriers or individuals with chromosomal disorders (i.e. down syndrome or Edward’s syndrome).
- Any woman over the age of 35.
- Women experiencing repeated pregnancy complications.
- Women who’ve experienced numerous failed fertility treatments.
