The Duke of Sussex was left with a chilly willy after a 200-mile charity expedition to the North Pole in March 2011 - which raised £2 million for the Walking with the Wounded - and just a month later at Prince William and his sister-in-law Catherine's nuptials he was still suffering with his wintry wand.

He wrote in his new memoir 'Spare': "Upon arriving home I’d been horrified to discover that my nether regions were frost nipped as well.

"And while the ears and cheeks were already healing, the todger wasn’t. It was becoming more of an issue by the day."

Harry, 38, admitted his father Prince Charles, 74, was very "sympathetic" about his frostbitten ears and cheeks following the trek.

He said: "Pa was very interested, and sympathetic about the discomfort of my frost nipped ears and cheeks."

The royal also confirmed in the bombshell book that both he and William, 40, were circumcised as children, despite reports claiming their late mother Princess Diana - who died in 1997 aged 36 - had "forbidden it".

He added: "There were countless stories in books, and papers (even The New York Times) about Willy and me not being circumcised.

"Mummy had forbidden it, they all said, and while it’s absolutely true that the chance of getting penile frostbite is much greater if you’re not circumcised, all the stories were false. I was snipped as a baby."

Harry later went to the doctor after using Elizabeth Arden cream on his polar privates.

The duke embarked on the gruelling, 13-day North Pole trek alongside four ex-servicemen, who were all injured in Afghanistan.
