but these things are only different on average; some cis women are taller and stronger and even have a natural variation in hormone concentration (also, early transitioners who start hormones before their birthsex puberty can avoid some of these differences; trans girls end up, on average, the same height as cis women). Also, a study in the Journal Of The Endocrine Society found bone density does decrease closer to that of cis women (although of course bone size doesnt change).
