DNA Ancestry is here! Learn more about a donor's ethnic background with DNA Ancestry. Available for over 80 donors!

DNA Ancestry is a report of a donor’s geographical ethnicity obtained through DNA analysis. It includes ancestry data for 26 unique geographic regions and ethnic groups. DNA Ancestry combined with a donor’s self-reported ancestry creates a more detailed picture of a donor which can help with donor selection. It also provides future children with more details about their own ancestry, while maintaining privacy for our donors and client families. This is a Level 1 item that can be downloaded for free from a donor’s profile page. (DNA Ancestry reports are not available for all donors.)

National averages range from 3-4 insemination cycles per successful pregnancy. We recommend purchasing at least 5 vials per child to guarantee your donor remains available until reaching your personal family goals. Additionally, you get 1 Year FREE storage if you purchase 4 or more vials ($475 value).


Our donors sell out and retire quickly! We have thousands of clients forced to choose between a new donor or not having a second child because they chose not to store vials for future use while they were available. To help you plan for your future, we offer 3 Years FREE storage if you purchase 3 Years+ vials ($1,050 value) - as well as the ability to sell back any unused vials that have not left our control.
