The Global Sexual and Reproductive Health Service Package for Men and Adolescent Boys has been developed to support providers of sexual and reproductive health (SRH) services to increase the range and quality of services to meet the specific and diverse needs of men and adolescent boys. This package focuses specifically on the provision of such services integrated within clinical and non-clinical contexts and follows a gender-transformative approach. It covers men and adolescent boys in all their diversity and takes a positive approach to SRH, seeing this not just as the absence of disease, but the positive expression of one’s gender, sex and sexuality. In doing so, this service package contributes to efforts to ensure universal access to sexual and reproductive health and rights (SRHR) as prioritized in the Sustainable Development Goals. This package is in no way intended to detract from the sexual and reproductive health and rights of women and adolescent girls, nor to divert resources, funding or attention from much-needed SRH services and programmes for women and adolescent girls.
