One guy, okay? But this study points to still another potential therapeutic use for oxytocin, which sure seems like some kinda wonder drug.
A test published in April 2008) at Cedars Sinai examined whether inhaling oxytocin would help a male patient who couldn't orgasm. The docs had ruled out medical conditions, drugs and "psychological issues" as the cause of his inability to ejaculate. Yes, it did. He was able to ejaculate.
Why this worked is unclear from the abstract. My speculations:
Oxytocin relieves anxiety, and maybe this man had become so anxious about orgasm that he couldn't do it. (Although the researchers ruled out psychological issues, and I assume anxiety would classify.)
Oxytocin is responsible for erection and ejaculation (along with other chemicals). And a review of animal studies opined that the reason that SSRIs lower sexual desire and function could be because they decrease the sensitivity of oxytocin receptors. If this patient's oxytocin receptors had reduced sensitivity for some reason, the extra jolt of oxytocin could have been what was needed.
