An exploration of terminology related to sexuality and gender: arguments for standardizing the language.

There is currently no consensus on the best ways to define and operationalize research concepts related to sexuality and gender. This article explores some of the ways that sex/gender and sexuality terms have been used in health-related research and in keyword searches in the health sciences. Reasons for the diversity of terms and measurement approaches are explored and arguments for and against standardizing the language are presented. The article ends with recommendations for beginning a productive dialogue among health researchers to create some consistency in the terminology used to assess sexuality and gender.
