I think especially with the types of methods men vs. women use, a lot of men are much more committed to their actions when they choose suicide. By hanging oneself (something that probably isn't any more difficult for one gender or the other), you basically "guarantee" your own death. Making the decision to overdose on something gives you a chance to stop earlier and gives others more time to step in. I think this is an unconscious factor based on the causes that the decision stems from -- for example, it seems that women with bipolar disorder get more depressive episodes. Since they're more likely to try suicide during these episodes, that would explain the increased rate. Yet because a higher ratio of the men committing suicide are not suffering from bipolar disorder, it might mean that they've had depression for a larger period of time (making them take a firmer decision on how to end their life).
