Recently, mainstream English-language news organisations have been reporting that a 'male pill' will soon be available. A common theme running through many published articles is that women will not trust men to use these new male contraceptives, though rarely is evidence provided to support this claim. In order to understand this disconnect between women's distrust for men as a group and their trust in their male partners, this paper examines three dominant ideologies of masculinity that inhibit men's contraceptive trustworthiness as a group. First, there is a cultural belief that men have an uncontrollable sex drive, which interferes with their ability to contracept. Second, there is a commonly held idea that men are incompetent in domestic tasks, which impairs their ability to correctly use contraception. Third, there is a social perception that men are not committed to pregnancy prevention, or at least not to the degree that women are.
