carry heavy rucksacks
move weaponry and equipment by hand

There is nothing about males that make them more suited to be doctors. We also can see that in the demographics in some countries (e.g. the UK), there is a roughly equal balance of female doctors to male doctors.
Having mathematical ability is linked to intelligence, not sex.
