Have you found anything indicating that the 96% and 91% numbers are atypical?

Those numbers DO NOT indicate mature gametes!

"91% of transgender females had progressed beyond Tanner stage 2 and were offered an opportunity to bank sperm; 96% of transgender males were postmenarchal and were offered a referral to a reproductive endocrinologist at a nearby fertility practice."

Tanner stage 2 *is not* confirmatory or disconfirmatory for spermarche. Tanner stage 1 is literally "no signs of puberty," so it doesn't make sense to even consider sperm banking prior to stage 2. Postmenarchal AFAB patients are Tanner stage 4 & in a much better position.

Right, but "beyond Tanner stage 2" presumably means they're stage 3 or later? Agree that "in Tanner stage 2" wouldn't mean much but that's not what the paper says.

I don't know. I read this as "inclusive of Tanner stages 2 and greater." Either way, not indicative of spermarche, though 3 is significantly higher likelihood than 2. Guidelines for suppression of puberty with blockers call for Tanner stage 2 at minimum, AFAB or AMAB.

Thanks. Changing my mind towards "the guidelines permit transition early enough that the tradeoff with fertility is in fact quite absolute; few transitions actually occur that early but that does not seem to be because guidelines discourage it". WIll email study authors re >=T2.
