I thought we had a story on this previously here? In any case, be interesting to see, should in utero treatments show promise for affecting sexual orientation, if proponents of the "choice" theory of homosexuality will suddenly change their tune, and start arguing that it really was determined prenatally after all.
But only so it can be "treated" as a disorder. Or more likely they'll want to have it both ways, saying it should be reversed prenatally, but if it isn't, then the gay person still has a "choice" to ignore it if they want, as being a mere tendency.
But I'm not sure I like the sound of this, because it undermines the pro-gay contention that being gay is natural & normal. Even if not subjected to any kind of corrective treatment, I'm sure many people would interpret this to mean that being gay is an abnormality, a defect.
