Estrogen is also a natural hormone, but such treatments in menopausal women--whose bodies are supposed to be producing them at different levels than they once did--is not healthy. What I mean by "non-natural" is that such levels are not natural to that gender or stage of life.
Similarly, with oxytocin we're talking about exposing men to levels their bodies were not made to process, and I would be concerned about what health effects it might have.
