I understand the language concerns, but I see the study as a quite positive one.
Monkeypox were mostly studied in men, so even half of a study focused on women adds something relevant.
The study practically shows that results obtained from men can be applied on transwomen, but not on women.
No matter the language this study shows how important is to actually use sex, not only a gender (which some seems to be trying to support) in science.
It isn't a full victory, but it kind of confirms that transwomen are very different group.
