There's a great scifi story from the 50s by Robert Heinlein where a girl grows up, joins the service, is seduced and impregnated, has a baby, and is told in the recovery ward that she was born a hermaphrodite, and after the pregnancy her female set of organs are useless, so the surgeons have taken the male organs and set them up to see if they will develop, which they do. The newly male narrator now joins the time service, and in the course of his adventures goes back in time and seduces him/herself. At the end of the story he addresses the world: "I know who I am, but who are all you zombies?"
The story is worth reading because it also contains the BYLAWS OF TIME.

Which brings me to my question: Say you have gender dysphoria. Rather then go through a lot of major plumbing changes, what if there was a pill that could change your mind? Wouldn't that be as acceptable a solution? Mind you, I'm not saying such a pill exists, or even is possible. But wouldn't it be worth it to find out?
