European Fertility Group Calls for International Sperm Donation Limits

WireByte Staff · July 10, 2026

A European fertility organization has proposed a Europe-wide limit on the number of children a single sperm donor can contribute to, in an effort to prevent donor-conceived individuals from discovering hundreds of siblings. The move comes as genetic testing companies make it easier for people to trace their biological relatives.

Key points

  • The European Society of Human Reproduction and Embryology has proposed a Europe-wide limit on sperm donations to prevent donor-conceived individuals from discovering hundreds of siblings.
  • The limit would start with a Europe-wide cap, with the goal of eventually establishing international standards.
  • Many countries, including the UK, have banned anonymous egg and sperm donation, but genetic tests offered by companies like Ancestry and 23andMe have made it easier for people to trace their biological relatives.
  • Donor-conceived individuals have reported finding tens or even hundreds of half-siblings after using genetic testing services.

A European fertility organization has called for international limits on sperm donations to prevent donor-conceived individuals from discovering hundreds of siblings. The European Society of Human Reproduction and Embryology (ESHRE) made the proposal at a conference in London, where members laid out plans to start with a Europe-wide limit.

The ESHRE argues that the current lack of regulation has led to a situation where donor-conceived individuals are discovering large numbers of half-siblings. This has raised concerns about the welfare of these individuals, who may feel like they are part of a 'mass-produced' family.

The proposal is not without its challenges, however. Many countries have banned anonymous egg and sperm donation, but genetic tests offered by companies like Ancestry and 23andMe have made it easier for people to trace their biological relatives. This has created a situation where donor-conceived individuals can discover their siblings, even if the original donation was anonymous.

The ESHRE's proposal is seen as a step towards establishing international standards for sperm donations. While it is unclear what the final outcome will be, the proposal has sparked a much-needed conversation about the ethics of sperm donation and the welfare of donor-conceived individuals.
