This study found that hormone therapy does decrease muscle mass in M-F, but they still end up with mean muscle mass significantly higher than in cis women.

The conclusion from this study, in 2004-

We may summarize as follows:
1. Testosterone exposure has profound effects on muscle mass and strength, justifying the practice that men and women compete in sports in separate categories.
2. The response to testosterone exposure in men is idiosyncratic; similar plasma levels of testosterone do not produce similar effects on muscle mass and strength.
3. The effects of cross-sex hormones in the dosages commonly used have reached their maximum effects after 1 year of administration.
4. In spite of a large difference in testosterone exposure between men and women, there is a large overlap of muscle area between them.
5. Androgen deprivation of men induces a loss of muscle area, further increasing this overlap with women.
6. Therefore, depending on the levels of arbitrariness one wants to accept, it is justifiable that reassigned M –F compete with other women.

This one said there's not enough research done to come to a conclusion.

The conclusion from this study, in 2008....

Overall there is a paucity of data regarding the effect of transitioning on athletic performance. What performance data does exist was not taken from transitioned athletes; thus its applicability within an athletic population is uncertain. To date no study has conducted any sort of exercise test to assess athletic performance. The only study to have addressed transitioned athletes in competitive sport used a retrospective study design and considered muscle mass and Transitioned Athletes and Competition 16 haemoglobin content to be predictors of athletic prowess. Undoubtedly these factors do influence performance; however, in athletics the whole is greater than its parts and as such, performance during athletic events needs to be assessed. While to date the data available does not appear to suggest that transitioned athletes would compete at an advantage or disadvantage as compared with physically born men and women, there is not enough data available to fully substantiate this claim. Much more research needs to be conducted before a consensus can be made. However, due to the low prevalence of transitioned individuals in the population, conducting these studies will be challenging. Due to these complications we may never truly know whether transitioned athletes compete at an advantage or disadvantage as compared with physically born men and women.

What's really interesting is that I got to these from the resources section of the NCAA policy statement, which requires M-F to be on hormoe therapy for one year to compete as women.

They allow it, but so far I haven't found a study, even in their own references (although I haven't checked all the links yet), that says there's no advantage.

What did you find interesting about it?
