Male virility is a complex business, with implications not just for men’s love lives, but their health, too, as a new book reveals.
The author, Dr Ronald Virag, is a French cardiovascular surgeon and leading authority on male sexual health and erectile dysfunction (he pioneered the use of injections to treat the problem).
Here Dr Virag reveals some surprising facts about men’s sexual function – and what to do when it goes wrong . . .
Just as men develop grey hair and creaky joints as they hit middle age, from the age of 40, their blood vessels start to age, affecting their virility. The blood vessels become furred with fatty deposits, impeding blood flow to the penis.
This lack of blood also means that some of the tissue around the vessels becomes deprived of oxygen – another trigger for erectile dysfunction.
Before the age of 40, less than 10 per cent of men have concerns about their erections – after that, more than 50 per cent complain of problems, and it is a worry for the vast majority of the over-70s.
