(London Daily Mail) A prolific sperm donor who claims he has fathered more than 30 children used his fertility to get women into bed and must now pay £300,000 costs after a paternity row with a client turned lover.

In a landmark ruling today a judge found the man, known only as Mr F, was the legal parent of a two-year-old boy conceived after a series of trysts with a woman he met on the internet.

The sperm donor was so keen to make babies he advertised a ‘breeding party – a male-dominated orgy designed to get a woman pregnant’ online, the High Court was told.
