A teenager born from an anonymous sperm donation has managed to track down his biological father using a swab of saliva and the internet, in a case that could throw donor anonymity into disarray.

They said that guarantees of identity secrecy, which have been given to thousands of donors over the years, could prove worthless with the increase in such resources.
