Furthermore, children in the story have difficulty recalling a male Pokémon revealing that there is an imbalance in which prominence is given to male characters.

These are the organs that produce gametes (egg and sperm), the reproductive cells that will eventually meet to form the fertilized egg ( zygote ).
The pelvis is, in general, different between the human female and male skeleton.
