In the UK men kill themselves at a rate of 3 times that of women, but the rate for men is going down at the same time as the rate for women is increasing. Worldwide, the figure is much more equal, with 1.5 men to women.
Suggesting that women merely make "cries for help" is rot. Women merely tend, even in their darkest hour, to not want to make a fuss and use methods that mean that even in death they don't make a mess. The other problem is that the single biggest indicator that someone will take their own life is that they have tried previously, which might account for the fact that middle age is the modal time for suicide in both sexes in the UK, again, when looked at worldwide, 75+ is the modal age range.
So, in summary. In the UK, more men kill themselves than women, but the rate for men is falling, while the rate for women is rising and this merely means that the UK is moving toward a more Global norm for suicide rates.
