Sperm donation is becoming increasingly popular, but concerns are rising about the potential for individual donors to father an excessive number of children. The European sperm market is experiencing significant growth, leading to questions about the ethical implications of a single donor’s genetic material being used to create hundreds of offspring. While the exact number of children a donor can father varies by country and clinic, some donors are reportedly contributing to a substantial number of births across multiple regions. This practice raises complex ethical and social questions, including the potential for future consanguinity issues among offspring and the psychological impact on individuals discovering they have a vast number of half-siblings. Regulators and fertility clinics are grappling with how to best manage sperm donation to ensure both the welfare of donors and recipients, and to mitigate any long-term societal consequences.
