What is the family limit for each donor?

Standard Family Limits

Fairfax Cryobank creates sperm donor family limits based on several criteria.

Specifically, a donor’s sales will cease when 25 families (children from the same donor living in one home) have been reported in the US. International distribution stops when 15 families have been reported. After the family limits have been met, vials will only be distributed for sibling pregnancies. 

Families who have children by the same donor will be sold additional donor units, if available, as "Sibling Pregnancy Only" units.

 

Fairfax ID-Reserve Family Limits

 

Unlike our Standard family limits, the Reserve Donor program offers more limited donor access to families seeking more exclusive options. 

 

Reserve Donors are only sold at1 0 families or 20 families worldwide and have a 3 vial sale minimum per family slot.  The number of families for each reserve donor is noted on the specific donor on the site. 

 

 

 

In addition, we monitor the reported location of births and limit the geographic distribution of a donor consistent with the guidelines of the American Society of Reproductive Medicine (ASRM). It is important that everyone be diligent in reporting births to us to help us monitor the number of births associated with any donor.

Please go to the pregnancy reporting page on our website or call us with your information.
