A lot of men ask for enlargement surgery. And a very few ask for reduction surgery. The latter is very rarely done – though in 2015, a Florida urologist reported that he had successfully reduced the penile size of a young man whose penis was the size and shape of an American football (as a result of complications of sickle cell anaemia).

Enlargement surgery is pretty uncommon, so most men who ask for it will be disappointed.

Many men are obsessed with the size, and particularly the length, of their penises.

Women will probably find this incomprehensible, but there are actually numerous websites and blogs on which males discuss their penile length with each other and on which they advance ideas as to how it could be ‘improved’.

Most of this concern about the length of the phallus is pretty pointless, since recent research has shown that the majority of females could not care less about the length of the partner’s organ.

However, some of them do say that, given the choice, they would prefer a thicker penis to a thin one.

Another development of recent years has been the gradual realisation that widely-published and accepted figures for average penile length were actually wrong.

These figures, which have appeared in textbooks, medical journals, magazines and newspapers for over 50 years, have now been shown to be somewhat exaggerated. And those false statistics have made quite a lot of men feel inadequate about their length – when in fact they had nothing to worry about at all.
