🧬 Preimplantation Genetic Testing (PGT): Screening for Healthier Embryos

PGT is a cutting-edge technique used during in vitro fertilization (IVF) to analyze embryos for genetic abnormalities before implantation. It helps increase the chances of a successful pregnancy and reduces the risk of passing on inherited conditions.

🔍 Types of PGT
There are three main categories:

PGT-A (Aneuploidy): Screens for abnormal chromosome numbers, such as those causing Down syndrome or miscarriage2.

PGT-M (Monogenic Disorders): Detects single-gene conditions like sickle cell anemia or cystic fibrosis2.

PGT-SR (Structural Rearrangements): Identifies chromosomal issues like translocations or inversions that may lead to failed IVF cycles or early miscarriage2.

👶 Why It's Done
Improves IVF success rates by selecting genetically healthy embryos.

Reduces miscarriage risk and avoids transferring embryos with known genetic disorders.

Supports family planning, including sex selection in some cases.

Helps carriers of genetic conditions avoid passing them to offspring.

🧪 How It Works
Embryos are created via IVF.

At the blastocyst stage, a few cells are biopsied.

These cells are tested for genetic markers while the embryo remains viable for transfer.

🌍 PGT in Nigeria
Clinics like Nordica Lagos offer PGT services tailored to local needs, including screening for sickle cell disease—a common concern in West Africa. Non-invasive methods like NIPGT-A are also emerging, offering safer and more accurate testing
