A retired math teacher from the UK says he is the “world’s most prolific sperm donor”. Clive Jones claims to have fathered 129 children – with nine more on the way.

According to the Daily Mail, Mr Jones, 66, has been donating sperm for nearly a decade using Facebook.

Mr Jones, according to reports, began donating sperm for free through Facebook because of the “happiness” it brings to families.

“I think people would understand more if they saw the messages I get and the photos of the babies with very happy mothers.

“I feel the happiness it brings. I once had a grandmother message me thanking me for her granddaughter,” he said.

Mr Jones told said he started donating sperm for free at the age of 58 – and chose Facebook to connect with families because he could not become an official donor.

The 66-year-old has three children of his own.

“I read in some newspapers the plight of some people that can’t have children. Reading the newspaper, it explained how people were using Facebook to make arrangements,” he said.

Authorities, however, have issued a warning against Mr Jones’ activities. As per the rules of UK’s Human Fertilisation and Embryology Authority, all donors and patients should be treated at licensed clinics. – ndtv.com
