The decision about female leagues was made at a time when transsexuality wasn't socially acceptable and hence did not factor into it.

My point is, there are options to explore besides an outright ban. For example, a trans woman that goes through HRT will lose some of the advantages of her birth sex. However, she might still enjoy the advantage of the male frame, hence my suggestion of an additional penalty.

A unisex league as you suggested could also be a posibility, and one could think about introducing not only weight classes, but testosterone classes as well.

But again, the female leagues were established because of the physical differences between men and women. Yes, some trans people who undergo some medical interventions have some of their physical sporting attributes brought closer into line with the opposite sex, but it’s not all attributes and it’s not all athletes. It’s exceedingly complicated.

The reality is that female leagues was a cultural hack that worked well enough in the 20th century. But in a world where we recognise that neither sex not gender fit neatly into binary categories, it is impractical to assume that we can fit people into two sporting categories.

testosterone is highly variable even at the individual level to the point that I think this particular metric would difficult to implement.

Before the higher level of testing, there were plenty of rumors that fighters would overtrain (or cycle on steroids) to the point of plummeting their testosterone levels to be given a TRT exemption. By the time their baseline levels recovered by fight day, they could still be on TRT
