Abstract: This paper is a report of a study to determine the construction of male nurses as gay, and to describe how this discourse impacts on a group of New Zealand male nurses. This social constructionist study drew on data collected from existing texts on men, nursing and masculinity and interviews with 18 New Zealand men conducted in 2003-2004. Discourse analysis, informed by masculinity theory and queer theory, was used to analyse the data. Despite the participants' beliefs that the majority of male nurses are heterosexual, the stereotype persists. A paradox emerged between the 'homosexual' general nurse and the 'heterosexual' pyschiatric nurse. The stigma associated with homosexuality exposes male nurses to homophobia in the workplace. The heterosexual men employed strategies to avoid the presumption of homosexuality; these included: avoiding contact with gay colleagues and overt expression of their heterosexuality. These stigmatising discourses create a barrier to caring and, aligned with the presence of homophobia in the workplace, deter men's entry into the profession and may be important issues with respect to their retention.
