PGT: Genetic Testing of Embryos
60-second summary
PGT means testing a few cells from an embryo made by IVF, to look for chromosome or gene problems before it is placed in the womb. It can help some families, but it is not perfect and not needed for everyone. A genetic counsellor and your fertility specialist can help you decide if it suits you.

A few trophectoderm cells (future placenta) are removed from a day 5–6 blastocyst for genetic testing. The inner cell mass is not touched. Using PGT to choose a baby's sex is illegal in India (PCPNDT Act).
