This article aims to analyze the current literature on the social capital of transgender and gender diverse(TGD) people, given their fragility in social and health terms. The paper followed the guidelines developed by Tricco, Langlois, and Straus. The results of this paper reveal significant gaps in the literature relating to the social capital of TGD people and highlight how the various types of shared capital are for sexual health to be considered in future research on transgender health. This is the first article that analyzes in detail the relationship between social capital and TGD individuals. To date, there is no other scientific evidence in the literature in this regard. The paucity of scholarly evidence available for paper limits our ability to make conclusive statements about social capital of TGD people. Small sample sizes in the included studies warrant caution when deriving generalized conclusions about social capital.
