All Ryan Kramer needed was a swab of his cheek and nine days of genealogical research to identify his biological father, a man who thought he would be anonymous when he donated his sperm and never took a DNA test.

The year was 2005, when consumer DNA tests were in their infancy. Kramer was 15.

Thirteen years later, home DNA test kits have opened the floodgates for people who were born from sperm or egg donations to reveal the identities of their donors.

Donors used to be guaranteed anonymity, but things have changed, according to genetic genealogist CeCe Moore, founder of DNADetectives.

“It would be naive to think that a person could donate sperm or eggs and stay anonymous,” said Moore. “It isn’t going to happen.”

Even if people never send their own DNA to an ancestry website, donors can be identified indirectly by their genetic proximity to a distant cousin who took a DNA test.
