genetic testing on embryos during IVF to screen for genetic conditions or abnormalities prior to implantation
What is a "preimplantation genetic testing"?
Preimplantation genetic testing (PGT) is a procedure used during in vitro fertilization (IVF), where eggs and sperm are combined outside the body to create embryos, which are early-stage forms of human development. PGT involves examining these embryos for specific genetic conditions before they are implanted into the uterus. By removing a few cells from each embryo, doctors can check for genetic abnormalities or chromosomal issues. This helps ensure that only embryos without these issues are selected for implantation, reducing the risk of passing on certain genetic conditions and improving the chances of a healthy pregnancy.
