To determine how often embryos reported to be abnormal by preimplantation genetic testing result in liveborn infants. To evaluate whether the pregnancies that result from these embryos are higher risk for complications and whether the resulting babies have higher risk for health or developmental issues in the first five years after birth.

Genetic testing modality and results will be recorded

Pregnancy per transfer will be recorded

Patients in the study agree to provide medical records of their pregnancy.

Any genetic testing or fetal testing will be carefully reviewed and recorded by the study team.

For patients with live births, pediatric records will be collected for up to 5 years.

As well as surveys for developmental milestones.

There is no financial compensation for study participants
