You can bet whatever you want, but if you could maybe find a study on that, it would be a lot more helpful.

I won't hold my breath though, even if what you guessed were true, there is almost no funding for studying this issue so I sincerely doubt you will find such a study.

About the funding issue:

So why aren't we asking what's wrong with a culture that drives boys, much more than girls, to take their own lives? Even in academia, where you can find studies on the most obscure topics, there is little research explaining why boys are disproportionately killing themselves. The Center for Adolescence at Stanford, a nationally recognized clearinghouse on teen behavior, has no one on its long roster of experts who can speak on the topic. Neither does the American Association of Suicidology, an organization dedicated to suicide prevention since 1968. "As much as I would love to lead the charge (in finding out why boys kill themselves), try to go out and get funding for it," said Lanny Berman, the executive director of the association. So the association has an expert on female suicide but none on male suicide, even though suicide is an overwhelmingly male issue well beyond adolescence. Of the 30,622 Americans of all ages who took their own lives in 2001, 24,672 were men.

And just to respond to the response I usually get to that, back when there was some interest in the issue it was found that: "one common explanation of the sex difference in both types of suicidal behavior is that males use more lethal methods and therefore they are more successful. These differences, however, are not the complete answer since when method is held constant sex differences remain"
