If you or your partner is at risk of passing on a genetic disorder to your child, you may be candidates for preimplantation genetic testing — a procedure that involves IVF. After the eggs are harvested and fertilized, they are screened for genetic abnormalities via an embryo biopsy on day 5 of growth. Embryos that don’t contain identified problems can be transferred to the uterus.
Women aged 37 and older may want to perform genetic testing if undergoing an IVF cycle. As a woman ages, incidents of miscarriage is increased due to the genetic make-up of the egg.
