N/A, not applicable.
Including couples not yet finished with the maximum of three reimbursed cycles on June 1, 2019.
In 2%–3%, embryo quality after thawing was too poor to perform the genetic test; thus, they were not suitable for testing and transfer.
One of 19 pregnancies going >12-wk gestational age resulted in a midtrimester loss.
Not all have received genetic testing due to the patient being a minor.
