The Office for National Statistics reported that 75% of the 6122 suicides in the UK in 2014 were undertaken by men. That's roughly 12 men every day. Shockingly, many of those will not have been in contact with any mental health professional. Only 53% of men who have felt depressed have actually spoken to anyone about it.
Throughout the history of mankind, the male persona has been the epitome of stoicism, strength and courage. The male heroes from childhood stories instil in us the (perhaps dangerous) notion that the best kind of man is all of these things, and therefore dependable in the face of great adversity. Maybe the need to be strong, physically and mentally, goes some way to explain why men often only seek help when the mental condition has become extreme, making it all the harder to treat.
