Sperm Donation Risks: 23 Children Born with Rare Gene, 10 with Early Cancer
- Families across Europe have discovered that children conceived via sperm donation are carrying a rare gene linked to early-onset cancers.
- A study indicates that 67 children were born from this donor between 2008 and 2015 across eight European nations.
- Edwige Kasper,a pharmacy doctor and oncogenetic biologist at Rouen University Hospital,is scheduled to present these findings saturday at a European Genetic Society congress in Milan.

Families across Europe have discovered that children conceived via sperm donation are carrying a rare gene linked to early-onset cancers. The affected children were conceived using sperm from a single donor at a Danish center years ago, according to reports in *Le Figaro* and *The Guardian*.
A study indicates that 67 children were born from this donor between 2008 and 2015 across eight European nations. Of those children, 23 have been diagnosed with early cancers, suggesting they inherited the rare gene.
Genetic Link Presentation at European Congress
Dr. Edwige Kasper,a pharmacy doctor and oncogenetic biologist at Rouen University Hospital,is scheduled to present these findings saturday at a European Genetic Society congress in Milan. Kasper concluded that the gene is “probably carcinogenic.”
Sperm Bank Response: “Unable to Reduce All Risks”
The Danish sperm bank at the center of the issue told *Le Figaro* that while donors undergo “in-depth medical examination, an analysis of the family history and tests to detect possible genetic and infectious diseases,” eliminating all genetic transmission risks remains “unfeasible.” The sperm bank added that “systematic or preventive screening methods would not have allowed to detect this mutation.”
Researcher Calls for Stricter Limits on Donor Conception
Speaking with *The Guardian*, Kasper advocated for limiting the number of births from a single donor. She urged for “a European limit to the number of births or families for the same donor.”
Kasper also suggested families “prefer a PMA in France,” where regulations already limit sperm donation to ten children per donor.
The Danish donation center at the origin of these European births currently caps conceptions from a single donor at 75 children.
Sperm Donation and Cancer Risk: A Q&A
What’s the Main Concern Regarding the Sperm Donor?
The primary concern is that children conceived via sperm donation from a single donor are carrying a rare gene linked to early-onset cancers. This has affected dozens of children across Europe, according to recent reports.
how Many Children Are Impacted?
A study indicates that approximately 67 children were born from this single donor between 2008 and 2015, across eight European nations. out of those, 23 children have been diagnosed wiht early cancers.
Which Countries Were Affected?
The provided source material only mentions that children across eight European nations were affected. The specific countries are not named.
What Kind of Cancer Is Linked to the Sperm Donor?
The article states the children have been diagnosed with “early cancers,” but it does not specify the type of cancer.
Where Did the Sperm Donation Take Place?
The sperm came from a Danish center.
What Do Experts Say About the Genetic Link?
Dr. Edwige Kasper,a pharmacy doctor and oncogenetic biologist,is scheduled to present these findings at a European Genetic Society congress. She has concluded that the gene is “probably carcinogenic.” This means the gene likely increases the risk of developing cancer.
What’s the Sperm Bank’s Response?
The Danish sperm bank at the center of the issue stated that while donors undergo in-depth medical examinations, family history analysis, and tests to detect genetic and infectious diseases, eliminating all genetic transmission risks is “unfeasible.” The sperm bank also stated that “systematic or preventive screening methods would not have allowed to detect this mutation.”
What screening Methods are Used for Sperm Donors?
According to the Danish sperm bank, donors undergo:
- In-depth medical examination
- Analysis of family history
- Tests to detect possible genetic and infectious diseases
Are There Calls for Changes in Sperm Donation Practices?
Yes, Dr. Kasper has advocated for stricter limits on the number of births from a single donor. She urged for “a European limit to the number of births or families for the same donor.” She also suggested that families “prefer a PMA in France,” where regulations limit sperm donation to ten children per donor.
What Are the Current Limits on Sperm Donation in Different Countries?
The article mentions a few details on limits, as summarized below:
| Country/Center | Limit on Children per Donor |
|---|---|
| France | 10 |
| Danish Donation Center | 75 |
what’s the Significance of the Findings Being Presented at a European Congress?
Presenting the findings at the European Genetic Society congress in Milan suggests that the issue is being brought to the attention of the broader scientific and medical community. This may prompt further research, discussion, and potential changes to sperm donation practices across Europe.
