Frogger, you ask a good hypothetical question...and I think I would answer it this way, but leaving some room for more consultation. I'm sure that tests would be run, to determine one over the other gender, BEFORE the operation was performed. With consideration of the parents, their clergy, (if one was requested), and the family. I'm sure that if that operation was performed, there would be counseling that could be referred to, by the physician, or facility responsible for the operation. I've never been in that situation, and could counsel possibly, but, again, I'd rather defer to those more suited and qualified. That being said, I feel strongly, that I could counsel the parents, as to other related issues.
I'll tell you, if, that ever arises, which I'm pretty sure it won't, I'll think of you, and your question.
I, mostly, have taken on any more counseling, for marriage and family, and presently work pro bono...though I assure you my results have been astonishing, as to percentage of recovery.
Good question, though. My answer is certainly not 'etched in stone' infallible.
