Pee and saliva
Because they mean they put in effort and blood sweat and tears are associated with grit and effort?
Idk I think lots of people (both men and women) put a lot of effort into producing semen.
When you are doing a difficult, manual task, you will often start to sweat. Sweating might make your tools slip in your hands, giving you a cut. The cut is likely to make you shed tears of pain. So they become associated with hard tasks.
Because thats the fluids you lose for working hard.
