Preimplantation Genetic Diagnosis (PGD)
Preimplantation Genetic Diagnosis (PGD) and Preimplantation Genetic Screening (PGS) are advanced techniques used to identify genetic abnormalities and chromosomal disorders in embryos created through in vitro fertilisation (IVF).
Benefits of PGD and PGS:
- Detects genetic defects: PGS checks the chromosomal status of an embryo, testing all 23 chromosome pairs.
- Prevents failed miscarriages: Identifying problematic embryos can help prevent failed miscarriages by selecting healthier ones.
- Avoids pregnancy termination: Couples can avoid the difficult decision of ending a pregnancy later.
- Offers an alternative to prenatal diagnosis: PGD provides another option for couples with single-gene defects who might otherwise rely on prenatal testing.
