Some patients with chromosomal abnormalities can greatly reduce the incidence of fetal genetic disorders by undergoing screening with preimplantation diagnostic techniques. This group of patients can have a healthy child after IVF treatment. It is recommended that both partners undergo detailed chromosomal and genetic genetic testing prior to IVF treatment. After the embryos are grown, they need to be tested for genetic information, and those with abnormalities are eliminated and healthy embryos are selected for implantation so that the genetic risk can be minimized.
