Jonathan Jacob Meijer
Jonathan Jacob Meijer (born 1981/1982) is a Dutch musician and a sperm donor, who as of 2023 resides in The Netherlands. As of April 2023, he is estimated to have fathered between 500 and 600 children.
Sperm donation
Meijer started giving sperm donations in 2007.
In 2017, Meijer was banned from donating sperm to Dutch clinics after the Dutch Society of Obstetrics and Gynaecology revealed he was the father of over 102 children in 11 different clinics, whom only 6 were spermbanks, and the other 5 he donated as a private donor for couples he met online. The Dutch Donor Child Foundation determined that in addition to the 102 fathered via clinics, at least 80 additional children in the Netherlands were fathered via private arrangements.
After his Dutch ban, Meijer continued donating to international clinics such as Cryos International, as well as private websites. Meijer keeps close contact to many of his donorchildren, visiting them at birthdays, video calls, traveling abroad to meet with them and doing "donor days" where he and a big group of parents and the donorchildren meet up. Meijer has always been open about his identity and the privately conceived donorchildren are familiair with the fact that Meijer is their donorfather.
In 2023 a civil lawsuit was lodged against Meijer by the Donorkind Foundation, requesting court action due to fears of unintentional incest amongst the children and due to violating the Dutch limit of 25 donor children. Meijer's defence stated that he merely wanted to help parents who were unable to conceive, and that a decision against him would amount to legal castration. Meijer told the court that at present he only donates to parents who have already fathered a child with him. In April 2023, a Dutch court ordered Meijer to stop donating sperm and subjected him to a 100,000 Euro fine for each future infraction. In addition Meijer was instructed by the court to request destruction of his semen stored in stock by clinics, unless held in reserve for parents of children conceived by his sperm. The court determined that Meijer "deliberately misinformed" donation recipients about the number of children he had fathered. The court found that this creates a "huge kinship network, with hundreds of half-siblings" and that it is "sufficiently plausible" that the children will suffer psychological trauma as a result.
YouTube
Meijer has a YouTube channel with more than 4900 subscribers in which he posts his music and videoblogs mainly about nature, the raw carnivore diet and religion and spirituality.
