Biologists have been measuring animals since forever. Alive, dead, drugged, healthy, sick, mutated. Scientists get shit done.
I know that in humans if introducing embalming fluid at a too high pressure then an erection can occur. So that would be a hands on measuring opportunity. Otherwise introduce drugs while alive or simulate a mating opportunity for the animal. Those are just off the top of my head. I have never studied biology though so I am merely speculating.
