A Devastating Genetic Legacy: Unforeseen Risks of Donor Sperm
A sperm donor, unknowingly carrying a cancer-increasing mutation, has fathered at least 197 children across Europe, revealing a deeply troubling consequence of unregulated sperm donation practices. The incident underscores the potential for unforeseen genetic risks when screening processes are insufficient.

A Horrific Diagnosis and Lifelong Burden
The discovery of a significant genetic mutation within the donor's sperm has resulted in a “dreadful diagnosis” for affected families, presenting a “very challenging diagnosis” with a “lifelong burden” of living with the risk of cancer. Women conceived with the donor’s sperm are now undergoing rigorous annual MRI scans and abdominal ultrasounds to detect potential tumors, with many opting for preventative breast removal to mitigate the risk.

The Growing Crisis: Multiple Cases and Early Deaths
Concerns were raised at the European Society of Human Genetics this year, with doctors identifying 23 children with the variant out of a total of 67 children known at the time, ten already diagnosed with cancer. Tragically, some children have developed two different cancers, and some have died at a very early age. The case highlights the urgent need for stricter oversight of donor sperm usage.

A Mother’s Fear and Determination
Céline, whose child was conceived with the donor’s sperm fourteen years prior and carries the mutation, received a notification from the fertility clinic she used in Belgium. “I’m urging her to get her daughter screened,” she stated, expressing “absolutely no hard feelings” towards the donor while emphasizing the unacceptable risk posed by the sperm, which she described as “unclean and unsafe.” She acknowledges the looming threat of cancer, stating, “We don’t know when, we don’t know which one, and we don’t know how many,” and affirms her determination to fight any potential development.

A Network of Half-Siblings and Unforeseen Implications
The scale of the issue is staggering, with the donor’s sperm utilized by 67 fertility clinics across 14 countries. The case raises critical questions about the social and psychological implications of having hundreds of half-siblings, a concern highlighted by Sarah Norcross, director of the Progress Educational Trust, who emphasizes the need to "fully understand the potential social and psychological implications" and acknowledges the "potential trauma" involved.

Stricter Limits and Ongoing Debate
Current screening processes, which accept only 1% to 2% of all donor applications, are seen as insufficient. The European Society of Human Reproduction and Embryology recently proposed a limit of 50 families per donor, although they acknowledge this would not necessarily mitigate the risk of inherited rare genetic diseases. The incident reignites the debate surrounding appropriate donor limits and the balance between fertility treatment access and patient safety.

The Role of the Sperm Bank and Future Safeguards
The European Sperm Bank emphasized that it is “generally safer to have a child using donor sperm when donors are screened thoroughly” in accordance with established medical guidelines. “It is important, particularly in light of this case, to recognize that thousands of women and couples lack the opportunity to have children without the assistance of donor sperm.”
