Can IVF reduce genetic risk?
For couples with a known genetic risk, IVF with preimplantation genetic testing can substantially reduce the chance of an affected pregnancy.
Preimplantation genetic testing (PGT) analyses a few cells from an embryo before transfer. Only unaffected embryos are selected, which avoids facing a diagnosis later in pregnancy.
Types of PGT
- PGT-M — for a specific single-gene condition known in the family
- PGT-SR — for a parental structural chromosome rearrangement
- PGT-A — screening embryos for chromosome number
Important caveats
PGT reduces risk but does not eliminate it. Prenatal diagnosis is still recommended in the resulting pregnancy for confirmation. The right approach is decided jointly with your fertility specialist after genetic counselling.

Most pregnancy complications are not anyone's fault. Understanding the underlying cause is the first step towards answers.
Recurrence risk depends entirely on the underlying mechanism — which is why finding the cause matters so much.
Genetic testing is not routine for everyone. It is indicated when the result would change diagnosis, management or future planning.
