This is an interesting review of studies on advantages of trans people in sports. Now the date is old. I noticed it was published in 2016 so there maybe a more modern review but a quick google search did not produce it for me. I have been interested in the medical science of this subject because most of the time it is only dealt with on an emotional level. This article is very long and some times very tedious. So I am only going to post the intro to the review and its summary conclusion. If you want to dig through the data please go to the link above. Thanks.

Sport and Transgender People: A Systematic Review of the Literature Relating to Sport Participation and Competitive Sport Policies
Whether transgender people should be able to compete in sport in accordance with their gender identity is a widely contested question within the literature and among sport organisations, fellow competitors and spectators. Owing to concerns surrounding transgender people (especially transgender female individuals) having an athletic advantage, several sport organisations place restrictions on transgender competitors (e.g. must have undergone gender-confirming surgery). In addition, some transgender people who engage in sport, both competitively and for leisure, report discrimination and victimisation.
To the authors’ knowledge, there has been no systematic review of the literature pertaining to sport participation or competitive sport policies in transgender people. Therefore, this review aimed to address this gap in the literature.
Eight research articles and 31 sport policies were reviewed.
In relation to sport-related physical activity, this review found the lack of inclusive and comfortable environments to be the primary barrier to participation for transgender people. This review also found transgender people had a mostly negative experience in competitive sports because of the restrictions the sport’s policy placed on them. The majority of transgender competitive sport policies that were reviewed were not evidence based.
Currently, there is no direct or consistent research suggesting transgender female individuals (or male individuals) have an athletic advantage at any stage of their transition (e.g. cross-sex hormones, gender-confirming surgery) and, therefore, competitive sport policies that place restrictions on transgender people need to be considered and potentially revised.Keywords: Gender Identity, Sport Participation, Competitive Sport, Sport Organisation, International Olympic Committee
The majority of transgender people have a negative experience when engaging in competitive sports and sport-related physical activity. There is no direct and consistent research to suggest that transgender female individuals (and transgender male individuals) have an athletic advantage in sport and, therefore, the majority of competitive sport policies are discriminatory against this population. There are several areas of future research required to significantly improve our knowledge of transgender people’s experiences in sport, inform the development of more inclusive sport policies, and, most importantly, enhance the lives of transgender people, both physically and psychosocially.
