Heck, I can see the potential for abuses, too, mostly in the form of parents forcing it onto their children during the window between the onset of puberty and the age of 18, and that’s the mildest form. What Saudi Arabia (or Utah, for that matter) would do with it, for example, I can only speculate.
That said, I’m still not opposed to the development of such a pill, because I dislike putting prior restraints on science. In either case, it strikes me as an absurdly inefficient line of research to solve the alleged problem of helping gay people reproduce. As described in other posts, the methods to do so are well-established and (heh) straightforward.
