What is PGT (genetic testing of embryos) and do I need it?
Pre-implantation genetic testing (PGT) tests embryos before transfer. Three types:
• PGT-A (aneuploidy): tests for chromosome number abnormalities. Used for advanced maternal age (≥38), recurrent miscarriage, prior IVF failure.
• PGT-M (monogenic): tests for specific genetic diseases when known parental mutations exist (cystic fibrosis, sickle cell, BRCA, etc.).
• PGT-SR (structural rearrangement): for parents with known chromosomal translocations.
You need PGT-A if: ≥38 years, ≥2 miscarriages, ≥2 failed IVF cycles, or known elevated chromosomal risk.
You don't typically need PGT-A if: <35 years, no miscarriage history, first cycle. Cost-benefit doesn't justify it for low-risk patients in many cases.
