Preimplantation Genetic Testing (PGT-A)
Preimplantation Genetic Testing (PGT-A) is a procedure used to test embryos for chromosomal abnormalities before they are implanted into the uterus during IVF. This test helps to ensure that only healthy embryos are selected, improving the chances of a successful pregnancy and reducing the risk of miscarriage or birth defects.
1. What is PGT-A?
PGT-A is a test to screen embryos for chromosomal abnormalities before they are implanted in IVF.
2. Why is PGT-A done?
It helps ensure embryos are healthy and reduces the risk of miscarriage or genetic disorders.
3. Who needs PGT-A?
Couples with a history of miscarriage, genetic disorders, or IVF failures may consider it.
4. How is PGT-A performed?
Embryos are biopsied during IVF, and the biopsy samples are tested for chromosomal abnormalities.
5. When is PGT-A done?
It is performed after the embryos are created in the lab but before they are implanted.
6. Does PGT-A increase IVF success rates?
Yes, it helps select healthy embryos, improving the chances of successful implantation.
7. How long does the PGT-A process take?
The testing takes about 7-10 days after the embryo biopsy is performed.
