P s y c h 3 a c 3 : h u m a n s e x u a l i t y - p a g e | 1. Eggs are very expensive: we have about 400 from birth to death. Each egg is limited and each egg stops you from reproducing for 9 months & takes energy for the mother to take care of it, keep it healthy. Once the egg is fertilized the fetus takes a lot of your energy, you must go through labour which is potentially dangerous then there are many expenses after birth. This is why you want to invest your time and energy for a high quality baby. Sperm is cheap: you make 12 million sperm per hour; you can have as many babies as however many times you have sex. You can leave after sex and not care for the baby.
