Netflix's documentary series "The Man with 1,000 Kids" was released in the UK in July 2024. It takes an in-depth look at the actions of a prolific Dutch sperm donor, called Jonathan, who allegedly may have fathered over 1,000 children. Episode one starts with personal accounts from women and couples who conceived their children privately with Jonathan's sperm and their shock, anger and concern when they began to learn about the alleged scale of his sperm donation activity. It opens with the question "What kind of man would do that?" and goes on to raise further serious issues and questions.
