There are no documented health risks for children born after PGT testing beyond the normal health risks to mother and child through IVF. Handling of the embryo, its biopsy, freezing, and thawing results in a small risk of damage leading to an embryo that does not implant. Generally, around 5% of embryos evaluated by PGT are lost due to such damage.

Another risk of PGT is inaccuracy in test findings, as the testing is not 100% accurate. For this reason, it is recommended that the patient undergo typical prenatal testing when she is pregnant, such as amniocentesis.

As PGT testing evolves, the prospect of selecting traits to pass on to a child through embryo selection might become another use of the technology. It was originally just used to increase healthy IVF births, and that is still the predominant reason for its use. PGT will undoubtedly be used more often in the future by parents to look for traits in embryo genetics they want to pass on to their children and selecting to not pass on other traits.

This puts PGT in the moral ground of eugenics, a past scientific attempt to improve the human population through selective breeding for desired characteristics. PGT experts see this as an increasing issue for clinics offering the service and for patients deciding on whether or not to use it. Debate is ongoing about which genetic traits should be identified, as well as on the need for laws to guide clinics and patients.
