It's about the body of the female being ready for (relatively) painless childbirth. Before a certain point of body growth, the baby simply won't fit, and after a certain point cartilage in the region ossifies and it becomes difficult again. This usually happens in the mid-twenties but can start as early as the late teens.
The former can lead you to a horrifying conclusion that genetically short women will have more difficulty during childbirth no matter their age.
