Organs

Wow, just learned some even more crazy stuff.aparrantly as a fetus in the womb we have both sets of sex organs the male and female. And if our body does not produce. Certain hormone at a certain time our organs began to develop into the female organs. But if it does begin to develop then the organs develop into the make internal sex organs.the two type of systems are called müllerian system (for the female sex organs ) and wolffian system( male sex organs). So it goes into much more detail but that is pretty much the summation of what goes on.naturally a fetus wants to be a girl, but certain hormone does not allow for it.
