Quote from: Apple on March 24, 2015, 08:59:44 PMCould you please elaborate?
They are in no way the same. It is true that everything's made from the same building blocks, but most parts don't end up functionally the same. You can turn testicles back into ovaries, erectile tissue back into vaginal rugae, etc. Yes there are analogous parts that can serve comparable functions, but for the major parts they are in no way the same (I'm postop for whatever my point of view is worth).
The erectile tissue (or inside of the foreskin) first off isn't the same color, doesn't produce mucus or natural lubricant that the vaginal rugae does, gets erect through blood swelling through the tissue, where as the vaginal canal expands due to the uterus retracting further into the body. You're saying that apples are the same as oranges here.
It is fundamentally impossible to convert these parts mentioned above back to their original building blocks, and then cause them to mutate back into the other sex's parts. Maybe next millennium I'll be wrong, I hope I am!
This isn't to discredit the fact though the the labia majora, minora, urethra, vaginal canal, and over all construction and function is replicated pretty darn well.
