Medical academic research done in various specialties shows sex disparity in terms of academic and leadership rank. Research shows that in many medical academic research fields, there are a greater number of men with higher academic and leadership ranks, as well as higher research productivity. This begs the question: What is the case for medical academic research specifically in physiology departments throughout North America? Upon review of the literature, we found that a knowledge gap still exists in North America regarding sex differences among the faculty of physiology. Our rationale for this study is that if a sex disparity among the faculty of physiology in North American academia is found, steps can be taken to lower this disparity. The very first step is identifying that a problem exists. Scopus was used to obtain the h-index, years of active research, and the number of publications and citations of each faculty member. The h-index was used as a metric of academic output and scholarly productivity. Univariate regression was run with the h-index as the outcome of interest and multiple linear regression analysis was used to determine factors associated with a higher h-index. The analysis showed that while the overall number of females holding academic positions in physiology departments throughout North America has increased over the years, a large sex disparity still exists between males and females in the field. This disparity exists not only in academic and leadership rank but also in research productivity, a key predictor of success in the field. This finding warrants that further work be done to find what is causing this disparity and how it can be addressed.
