Then what are we talking about? I'm confused.

Are we talking about the physical cost to produce eggs and sperm? I don't think that's that high. Also, a woman already has all her eggs at the time she's born.

Are we talking about the physical cost to maintain eggs and sperm? I don't think that's that high.

Are we talking bout the physical cost of pregnancy? If so, it doesn't make sense to say eggs and sperm. colonelpopcorn should have said pregnancy.
