Passing on genetic disease is a fear that many individuals feel they can do little about. Thanks to Preimplantation Genetic Diagnosis (PGD), couples can screen for genetic abnormalities to ensure transferred embryos are free from the hereditary disease. PGD is recommended for couples who are known carriers of a single gene disorder (genetic disease) like Hemophilia or Cystic Fibrosis.
Candidates for PGD testing
While anyone can benefit from genetic testing, there are certain groups of individuals who have a higher risk for genetic disease and who should carefully think about their options.
- Individuals who are known carriers for a genetic disease
- Individuals with a genetic disease
- Couples who have a child who was born with a genetic disease
- Those with a family history of a genetic disease
- Individuals who’ve had multiple miscarriages
- Individuals who’ve had multiple IVF cycles that failed
The PGD Process in Conjunction with IVF
In order to perform PGD, a customized IVF protocol is followed. A woman may be given fertility medication to produce multiple eggs - Mini IVF - or she may only grow her one monthly egg - Natural IVF. Once the eggs are mature, they are surgically retrieved. The eggs are analyzed for quality and are then fertilized with your partner’s or donor sperm. Embryologists are then able to monitor the embryos as they develop and analyze them for abnormalities. Then, only the healthiest embryos are transferred to the mother's uterus.
Several days after fertilization, a single cell is taken from each embryo. That cell is then analyzed to determine if genetic disease exists. If an embryo is found to have genetic disease, it is not transferred to the mother's uterus. During transfer, only embryos that were shown to be free of genetic disease are returned to the mother’s womb. Any surplus embryos are frozen and stored until they are needed for a future Frozen Embryo Transfer (FET).
