And, perhaps more curiously, I don't see any discussion in the release about the possibility of or attempts to control for what else might be changing in the life of someone _beginning hormone therapy as part of a gender-transition process_.

How much of the change they observe is caused by testosterone, and how much is the expectation that one is becoming more masculine (and the downstream behavioral changes/feedback loop created if the self is _noticing_ changes that reinforce this expectation?) This isn't to say the effect they observe isn't real, but the conclusion they've reached doesn't seem to follow from the methodology discussed in the release.
