Large   investiments   are   being   made   focalized   on   prevention   of   unwilling pregnancy and sexually transmitted disease in several countries, but the relevance of the problem requires the interest at international political levels. Contraception is a crucial human right for its role in health, development and quality of life. In spite of shortcomings of currently available male contraception, 1/3 of the couples that use contraception worldwide rely on male methods,  suggesting that the development of a safe, effective, reversible and affordable contraceptive method for   men   would   meet   a   critical   need⁽¹⁶⁾. Because   rates   of   unintended pregnancy, abortion and unintended birth are very high among adult women in the United   States, it   is   important   to   identify   interventions   that   can   increase contraceptive use in the population, such as vaccines. Currently, vaccines are still experimental and until now were tested in animal and in women of developing countries^(17,18). A research plan that rigorously assesses the impact of different approaches to increasing contraceptive use among adult and young women, should be an integral part of any long-term effort to prevent unintended pregnancy⁽¹⁹⁾
