That's the big one I can think of, and this usually arises in a very different context where it's easy to dehumanize those forced to take such tests: alleged criminals and children.

(Even in these contexts, peeing in a cup or taking a breathalyzer is quite a bit less severe than enduring a forced pregnancy. Mandatory blood draws for DUIs do upset a signifianct number of people. How you feel about employment tests and sports doping might depend on how you feel about economic coercion and whether it's truly "mandatory".)
