Belgium Donor Anonymity Plan Faces Bioethics Committee Blow

Belgium’s ambitious plan to abolish anonymity for sperm, egg, and embryo donors has run into unexpected resistance — not from opponents of transparency, but from the country’s own advisory body on bioethics. The Belgian Advisory Committee on Bioethics has issued a critical opinion warning that Health Minister Frank Vandenbroucke (Vooruit) is moving “too quickly,” recommending instead a phased “two-track” approach that would allow donors to temporarily choose how much personal data they share.

The Proposal at a Glance

The federal government approved a preliminary draft law on February 27, 2026, to end donor anonymity, as reported by VRT NWS. Under the proposed legislation, children conceived through donation would be able to request non-identifying information — such as hair color, eye color, and height — from the age of 12. From age 16, they would gain access to identifying details including the donor’s name, date of birth, and nationality. A six-month transition period would allow fertility centers to use existing anonymous sperm stocks, while past donors would retain the option to voluntarily give up their anonymity without being compelled to do so.

Minister Vandenbroucke framed the reform as a fundamental shift toward prioritizing the child’s right to know their origins. “Children must get every opportunity,” he said in February. “Knowing what wood you are carved from helps you better understand who you are. It is important for your mental well-being to stand strong in life. From now on, the child is central.”

The Bioethics Committee’s Warning

On June 24, 2026, the Bioethics Committee released Briefadvies nr. 22, its formal advisory opinion on the draft law, as detailed by VRT NWS. While the committee agrees in principle that irrevocable donor anonymity is outdated, it warned that an abrupt, complete abolition could backfire by reducing the pool of willing donors.

“We absolutely agree with the principle that anonymity should be abolished, but we would prefer to see this done in phases,” said Jan De Lepeleire, vice-chair of the Bioethics Committee, in an interview on Radio 1’s “De Ochtend.”

The committee proposes a temporary two-track system in which donors could choose between two options: full disclosure of their identity, or sharing only non-identifying information such as physical appearance, social and cultural background, and hereditary diseases. Under this model, donor-conceived children from age 16 could request full disclosure at regular intervals — every three to five years — with appropriate counseling for all parties involved.

A Committee Divided

The advisory was not unanimous. Some members opposed the two-track approach, fearing it would create a division among donor-conceived children — those who can access their donor’s identity and those who cannot. Advocacy group DonorFamilies has also argued against maintaining any option for anonymity, warning that a multi-track system could create inequities and that DNA technology has already made true anonymity virtually impossible.

Steph Raeymaekers, chair of Donorkinderen vzw, welcomed the change for future donor-conceived children but criticized that existing donor-conceived children remain excluded from the new rights unless their donors voluntarily come forward.

The Donor Scandal Catalyst

The push to end anonymity cannot be understood without the donor scandal that rocked Belgium in 2025. It emerged that a Danish sperm donor carrying a cancer-causing TP53 genetic mutation had fathered at least 53 children in Belgium — far exceeding the legal limit of six families per donor — and at least 197 across Europe, as documented in the VRT NWS donor scandal dossier. Investigations revealed systemic failures at Belgian fertility centers, including lost files, unapproved donor use, and inadequate oversight by the Federal Agency for Medicines and Health Products (FAGG). At least 29 sperm donors with genetic abnormalities were found to have been used beyond legal limits.

Unresolved Questions

The Bioethics Committee also raised practical concerns about the requirement for donors to share medical data lifelong. What constitutes “relevant” data? Who assesses it? What happens after the donor dies? These questions remain unanswered in the current draft.

What Happens Next

The Bioethics Committee’s advisory is non-binding, meaning Minister Vandenbroucke may choose to proceed with the original draft law. The proposal must still pass through the Council of State and receive parliamentary approval, where the debate over balancing a child’s right to know with the practical need to maintain donor supply is far from settled.

For Belgium — long a destination for cross-border fertility treatment in the so-called “baby-Thalys” phenomenon — the outcome will have implications far beyond its borders.
