I've always wondered if men are fortunate or unfortunate when it comes to this subject.
Sometimes I feel that it's a disadvantage for women to have a set number of eggs from birth. But at the same time, it also means that women do not have to use any energy to produce eggs, because they're all ready to go.
Men on the other hand are constantly regenerating sperm. That must use up a lot of energy. And considering that sperm regeneration isn't as healthy when men are older, women are definitely at an advantage.
What do you folks think?
