The primary aims of this literature audit were to, firstly, understand the extent of female representation in the participant populations of EIGD research; and secondly, within the studies conducted with females, to assess the quality of data pertaining to menstrual (and thus hormone) status of participants. Additionally, within the literature, female data (demographics and results) were typically combined with male data and reported together. ...not only is there an underrepresentation of females to begin with, but what data there is, is subsumed within the overall mean of the combined data making future analysis of sex-disaggregated data (e.g., meta-analyses) impossible. There is a need for a greater quantity of high quality data using rigorous methodology to ascertain and report menstrual status of female athletes, as well as sex-disaggregation of data, if we are to understand potential sex differences in EIGD.
