Fun fact: during early development the gonads of the human fetus remain undifferentiated; that is, all fetal genitalia are the same and are phenotypically female.

- So, if biological sex can't be changed,
- And if life starts at conception,
- Then all men are trans.

Sorry, Republican men. You made the rules.

@LadyDragonfly this is a fact indeed. I was lucky to follow the “old fashioned” dental study which was far more broad medical in the 70-ties and one of the anatomical professors in Amsterdam extensively teached on this topic.
