Hey there :)

The cost of reproduction differs between males and females because:

- The production of sperms is continuous within males. However, for females, the number of eggs produced is very limited, one egg per month. This means only limited number of offsprings. Overall, this makes the eggs more valuable than the sperms.

So from what i have understood, males have unlimited sperm and females have limited ovum. That's why, there is a different cost of reproduction for males and females.

Hope this helps !
