I guess I’m not so hung up on the synthetic verses natural argument you seem to be making... I do know that you can give an XY individual so much estrogen that no matter their chromosome, they begin to take on an exhibit female characteristics and behaviors and vice versa. I’m not a geneticis but the original discussion was about the physical anatomy of a male and female and the similarity or dissimilarity of the actual organs. I’ll stand by my original argument that the cliturous and penis are very similar as well as testes and ovaries...
