Therefore concentrating on such research might be a waste if time and money.
All the research done on this is a waste of time and money to prove the absolutely obvious. Or even worse, to "disprove" the absolutely obvious. Males shouldn't be in women's sports.
Concentrating the research onto puberty blocked males could create the appearance of a compromise without endangering women's sport at all. And the TRAs can't openly acknowledge that puberty blocked males will never be able to compete as athletes, due to the side effects of the meds.
It's ridiculous that sports organisations feel the need to compromise with insanity, but it's better than them entirely giving in to insanity, which seems to be the current trend.
(And of course no one without a medical need for it should be on puberty blockers but that's a separate discussion.)
