Genetic Disease Testing

Sperm Donor Testing

It is essential to have a comprehensive understanding of genetic conditions and genetic inheritance in order to provide the best possible donor screening for inherited conditions.  Fairfax Cryobank provides the expertise of board-certified clinical geneticists in evaluation of the donor's medical and family history as well as reviewing the test results of the extensive genetic screening performed on all sperm donor applicants.  Any applicant with a family history that places him at higher than normal risk of transmitting a genetic condition is rejected.

Any candidate that is identified as a carrier or exhibits evidence of any of these diseases is not accepted into the donor program.
