Men are often overlooked in discussions of human trafficking and those who are targeted by trafficking enterprises. Reflecting this bias, trafficking in males has been under-considered in research. This despite noteworthy signals that many males, adult and minors, are subjected to trafficking exploitation. Often these severely exploited male victims, especially in the context of migration, are overlooked, with women and girls identified more commonly as victims of trafficking. This deficiency in identifying and assisting males who have been victims of trafficking exploitation needs to be addressed. “Trafficking in persons” must be understood and addressed as affecting all victims: women and men, adults and minors. In Belarus and Ukraine, male victims accounted for 28.3 per cent and 17.6 per cent of the IOM-assisted caseload respectively between 2004 and 2006. Through the lens of trafficking in males (primarily adult men) from Belarus and Ukraine, this study considers male victims’ pre-trafficking life (namely their personal, family and socio-economic background), trafficking experience (from recruitment, through transportation and during exploitation) and post trafficking experience and needs. The report examines, on the one hand, what is known about this less-considered profile of trafficked persons and, on the other hand, what can be done to meet their needs, both as a means of assistance and protection. The study draws on primary data collected about 685 trafficked males assisted by IOM and its partners, through IOM’s Counter-Trafficking Module Database in Geneva as well as qualitative information from interviews with and case files of assisted men. The research findings should not be read as representative of the full scope of trafficking in either country; they are instead representative of trafficked males who have been identified and received assistance and not male trafficking victims generally.
