“We Have to Stop This Man”: Mass Sperm Donor Fathered 121 Kids - DutchNews.nl
Investigators say the 43-year-old donor used online contacts and sperm banks, while mothers and a foundation are pressing him to stop.
- An investigation by Nieuwsuur revealed that a 43-year-old man from Groningen has fathered at least 121 children as a sperm donor. He remains active, operating outside licensed clinics to approach women directly.
- Dutch clinics are limited to 12 families per donor, but private arrangements face no legal maximum. This regulatory gap allows donors to father hundreds unchecked, as investigators found clinics produced at least 85 mass donors last year.
- Mothers report the man lies about his child count and remains evasive when pressed. Some women told Nieuwsuur he sent sexually suggestive messages; one from the Randstad sought police help.
- Stichting Donorkind and several mothers demand he stop, while the health ministry inspectorate IGJ called the case "very undesirable" but noted it oversees only clinics, not private conception.
- Traces of his activity appear in Germany and at Danish sperm banks. This mirrors Jonathan Meijer, a mass donor who fathered some 550 children worldwide before a court ordered him to stop in 2023.
