Basically, across most developed countries, women attempt to commit suicide 3x more than men, but men complete suicide 3x more than women. So men are approximately 10x as likely to succeed when they do try.

This is a combination of male suicide attempts being underreported and gendered differences in suicide as a cry for help vs a desire to end it all. There's also a minor statistical effect where a single suicidal women will attempt suicide multiple times vs a single suicidal male attempting it once (so you get different numbers comparing suicide attempts by gender vs people who have attempted suicide by gender).
