John Fury, the father of WBC heavyweight champion Tyson Fury and unbeaten fighter Tommy Fury, claims he has insured his testicles for £10 million.

The 58-year-old is regularly seen with his sons ahead of their fights, becoming a popular public figure in recent years.

He’s known for his outspoken nature and regularly drops sensational soundbites in interviews. This could be the most outrageous yet though.

In a chat with, Fury revealed: “I’ve insured my nuts for £10 million – believe me there is good stuff that comes out of them.

“I’ve got world champion nuts in these trousers, breed some kings I do. There are only champions coming out of these nuts — it’s been proven hasn’t it?”

Tyson is one of the greatest heavyweights of his era, most recently defeating Dillian Whyte at Wembley Stadium.

Tommy, meanwhile, is 8-0 and set to return to action next month on the undercard of Floyd Mayweather vs Deji.

Roman Fury also made his professional debut at the weekend in a winning effort.

Fury added: “Words cannot express how proud of Tyson and Tommy and all my family I am. I feel like I’m a world champ sometimes.”

In an interview with Behind The Gloves, he backed up his father’s recent investment, adding it was a shrewd one to make.

‘The Gypsy King’ said: “He insured them because that sperm produced the heavyweight champion of the world and it’s very valuable.

So, if anything happens to him, even at his age, he could still extract a few champions out of those, so we’ll see.

“See me, I’ve become heavyweight champion, but I’ve never produced a heavyweight champion.”

Tyson did retire from boxing back in April, but reversed his decision to ‘save’ the division after Joshua was beaten by Oleksandr Usyk.
