The rate of suicide among young people in Ireland is one of the highest in Europe, figures show.
An estimated 165 teens and young men took their own lives in the Republic of Ireland in 2011, while another 72 died by suicide in Northern Ireland.
The cross-border Men's Health Forum in Ireland (MHFI) said the high numbers in both jurisdictions coincide with the economic downturn and increasing levels of unemployment.
It called for targeted measures aimed at reducing the rate of self harm and suicide in the under-30s, which is fourth highest in the EU at 16 per 100,000.
Dr Noel Richardson, author of its report Young Men and Suicide Project, said there can be no quick-fix solutions to tackling the very grave statistics.
"But neither is there any place for inertia or ambivalence," he said.
"There is both a public health and a moral requirement to act. There needs to be a concerted effort to engage more effectively, and in a more sustained way, with young men, and to plan services and programmes with young men in mind.
"This report provides a blueprint and a roadmap for action."
It revealed that over the past ten years men have been five times more likely to take their own lives than women. And although rates of attempted suicide and deliberate self harm were traditionally higher among women, it is now more common among men.
