About the study

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.

• Euploid Transfer (other)

Sponsor: Stanford University · Participants: 300 · Started: Apr 11, 2019
