According to Wikipedia, the Journal of Adolescent Health is "a peer-reviewed medical journal covering adolescent health and medicine, including biological, psychological, and social aspects. "

Thanks to the Australia Men's Health Forum (AMHF), I found this one article about suicide rates and factors on it. It mainly concerned young LGBT people, but included some valuable information about young male and female suicides as well.

A summary of its findings about young male suicide can be found here on the website of the AMHF: https://www.amhf.org.au/research_confirms_5_uncomfortable_facts_about_young_male_suicide

I don't know if I'm just bad at searching, but it's hard to find articles there about male suicide alone.
