The nerd in me had to know. Happened to find this study from 2023.
https://pmc.ncbi.nlm.nih.gov/articles/PMC10385998/#:~:text=Research suggests there is a,female fencers (Figure 1).
"Research suggests there is a 17–30% difference in sporting performance (
Table 2) driven by the anthropometric and physiological differences between cis males and cis females (
Table 1 and
Table 3), which corresponds to fencing performance advantage for cis males over cis female fencers (
Figure 1). In addition, the literature highlights that once male puberty has been experienced, testosterone suppression does not reduce all the physiological advantages, such as lean mass, strength, power, and stature, to a degree that equals cis female values. Therefore, at this time the literature suggests that there is an unfair retained physiological advantage for trans women who have experienced male puberty when participating in female fencing competitions."
