The AATB requires that every donor have a three generation medical and genetic history in order to properly evaluate risk of genetic diseases in donor conceived offspring.
This consists of the donor, any children he may have had, his parents with their brothers and sisters including their children and the donor’s maternal and paternal grandparents with their brothers and sisters. All of this information is provided by the donor.
Except in rare circumstances no documentation is provided. It is dependent upon the donor’s knowledge of his family’s history and what he has been told by his relatives.
To one degree or another it will always be incomplete, and on occasion, be inaccurate. The sperm bank is dependent upon the donor to provide this information which in turn it evaluates.
This is best performed by a trained and qualified genetics counselor, either face to face or by telephone or by similar methods.
