Jonathan Meijer, the prolific sperm donor featured in Netflix's docuseries 'The Man With 1000 Kids,' is threatening to sue the streaming giant for slander. Meijer disputes the show's portrayal, claiming he fathered around 550 children, not 1,000, and denies allegations of mixing his sperm with another donor's. He argues he followed international sperm bank guidelines and provided more information to parents than typical clinics. Meijer, who did not participate in the series, has expressed his grievances through multiple YouTube videos, criticizing the negative connotations and factual inaccuracies. The docuseries, which details the risks of inbreeding among his offspring, has sparked significant controversy and currently tops Netflix's U.S. charts. Netflix has yet to respond to Meijer's claims.
