There is a known issue with men being more reluctant than women to see their GP about any health matters, and working class men are more reticent than middle class men, and northern men are more reticent than men from the Home Counties. You only have to look at heart disease & PCa statistics nationally to spot the pattern :-/
On the up side, it is very common now to see posters in the ladies' toilets at motorway services, etc., - "Does the man in your life get up during the night? Does he have problems emptying his bladder? Yes? Tell him to get a PSA test." I think it is brilliant.
