Sperm donor sued for fathering over 500 children and increasing incest risk.

A Dutch sperm donor, Jonathan Jacob Meijer, who allegedly fathered over 500 children worldwide, is facing a lawsuit over the potential increased risk of accidental incest. The DonorKind Foundation filed a lawsuit against Meijer, claiming he lied about the number of children he had fathered through sperm donations. Guidelines limit a person to 25 offspring or 12 women to prevent potential incest issues. Meijer may have in fact fathered as many as 102 children in the Netherlands, which prompted officials to blacklist him from any further donations in 2017. The Dutch Society of Obstetrics and Gynecology urged all sperm banks and clinics to stop using Meijer’s samples after his 2017 blacklisting, but he continued to offer his sperm "under the counter."
