Not when it comes to making babies. The problem female athletes have is that their body fat often becomes too low, which is bad in women, and causes them to miss periods and have lots of other problems – not good if you want to make babies.

It sounds crazy, but women can get too fit and female athletes often achieve this level. But women who are slim with curves in the right places don't, they have a good healthy level of fat reserves, which are perfect for making babies.

Hope that makes sense, Georgios, thanks for the comment!
