And again, what IS your obsession over this all about?
'Limits' = illegal if limits are exceeded. Athletes are 'tested'.
If you want to continue to pretend that that there are no rules to prevent unfair competitor, go right ahead. Reality is another matter.
More recent guidelines have focused entirely on testosterone levels, such as the IOC’s current guidelines, originally set in November 2015, which set limits on transgender athletes’ testosterone levels for them to be permitted in women’s competition categories.
Joanna Harper is a competitive runner, scientist, transgender woman and medical physicist at the Providence Portland Medical Center who advised the International Olympic Committee (IOC).[29]
She argues that the use of estrogen supplements and testosterone blockers (or physical castration via sex reassignment surgery) cause a decrease in muscle mass, and oxygen-carrying red blood cells and that this leads to a decrease in strength, speed, and endurance.[30]
According to Harper, every athlete has advantages and disadvantages. The greater height that a transgender woman may have gained before transitioning may be an advantage on the basketball court but it is likely to be disadvantageous to a gymnast.
[31] Eric Vilain, a professor of human genetics at UCLA and a consultant to the IOC medical commission, stated: "There is 10 to 12% difference between male and female athletic performance. We need to categorize with criteria that are relevant to performance. It is a very difficult situation with no easy solution."[32]
A 2017 systematic review of related literature reported that there is no direct or comprehensive evidence of transgender women having an athletic advantage over their cisgender counterparts at any stage of transition (e.g. cross-sex hormones or sex reassignment surgery).[33]
