The clinic understood to be first of its kind in the world has become operational at Södersjukhuset, one of the largest hospitals in Stockholm.
The clinic has been opened as part of a strategy to ensure 'gender equal' patient care.
"We are happy that we now can finally open the first rape clinic for men following the rape clinic for women," said Rasmus Jonlund, a press spokesman for the Liberal Party, which led the campaign for the department here, reported the Local.
"We think it is the first in the world. We haven't found another from our research on the world wide web," added Rasmus Jonlund.
'Emergency medical care for raped men will be free of charge, and offered around the clock, all year,' said Marie Ljungberg Schött, a local Moderate Party party politician and council representative on emergency care in a statement.
According to the Swedish National Council for Crime Prevention, around 370 cases of sexual assault on men or boys were reported across Sweden in 2014.
Sweden has the highest rape rate in Europe.
