The Cost of Men Sacrificing

Sperm versus eggs: What makes them expensive and cheap in terms of some of the cultural implications? Let's think about men sacrificing or men being, let's start with men being disposable. That's why we send men out to war and not women. You can't lose a lot of men and still have a viable culture. So from that perspective men are disposable in the service of the culture because one man like King Solomon famously had 300 wives and 600 concubines.
