I can't access the full paper, as I don't have a paid subscription to The Lancet, but this caught my eye in Vol.394 under the above heading:
"Men and women have noteworthy physiological differences. Beyond the traditionally accepted trends in bodyweight and physical stature, women are documented to have slower gastrointestinal motility, less intestinal enzymatic activity, and slower glomerular filtration rate than men.
'These translate into sex-dependent differences in medication absorption, distribution, metabolism, and excretion that can affect health outcomes'
Biological sex trumps gender identity. How inconvenient.
