Woman are more likely to get depression,have suicidal thoughts and attemp suicide, however men are more likely to die from suicide attempt.

Men usually use more deadly suicide methods than women, the more common are guns. In fact they place with more gun control usually see a drop of male suicide (the deaths from guns lower and death from other method slightly increase, but overall the the suicides of man decreases)

There is a lot of stigma around mental health. Men emotions are dismissed because society tells as that they shouldn't show emotions (or have them at all) and should just 'suck it up/man up', meanwhile women emotions are brushed off as them being to sensitive.

Also some people think that men can't have mental health problems and moments with mental health problems are just histeric, which is total bullshit.
