A court in the U.K. has waived anonymity by revealing the identity of a sperm donor who had offered his services on social media to lesbian women without informing them he had an inheritable condition.

James MacDougall, 37, fathered fifteen children to these women knowing he had Fragile-X syndrome, a genetic disorder that causes developmental delays, learning disabilities, and social and behaviour problems. Children with the condition may also have an intellectual disability.

MacDougall’s name and actions were made public in a family court as well as his attempts to have access to four of the children he fathered despite signed paperwork where he agreed not make contact with the children aged between three years and a few months old.

On Monday, Judge Nathalie Lieven ruled against MacDougall having parental responsibilities. Lieven also made the unusual move to name him, in what she said would hopefully make other women aware of what he’s done and stop them from using him as a sperm donor.

“A very specific benefit in him being named in the hope that women will look him up on the internet and see this judgment.”

“The usual approach of anonymity in the family courts should not be used as a way for parents to behave in an unacceptable manner and then hide behind the cloak of anonymity,” she said,

During the court proceedings, lawyers revealed that MacDougall elected to be a sperm donor even though he could not go through a regular clinic due to his condition.

In some legal agreements, MacDougall does list his condition, but without explaining it.

MacDougall was arrested for attacking one of the mothers whose daughter with him has developmental delays.

The judge has postponed the case until she receives a social services report.
