Spock: Each of us... At some time in our lives, turns to someone - a father, a brother, a God... And asks..."Why am I here? What was I meant to be?"
Kirk: Well, Bones. Do the new medical facilities meet with your approval?
McCoy: They do not. It's like working in a damned computer center.
McCoy: In simpler language, Captain, they drafted me!
Kirk: They didn't.
McCoy: This was your idea! This was your idea, wasn't it?
Kirk: Bones, there's a thing out there...
McCoy: Why is any object we didn't understand always called 'a thing'?
McCoy: Well Jim, I hear Chapel's an M.D. Now. So I'm gonna need a top nurse, not some doctor who'll argue every little diagnosis with me. And they probably re-designed the whole sickbay, too. I know engineers, they LOVE to change things.
Answer: Deltans exude an intensely potent and effective chemical substance known as pheromones, which act as signals arousing an intense sexual reaction in other species (in other ST material it's inferred that its potency is so extreme that a non-Deltan risks insanity in a sexual encounter with a Deltan). Upon entering Starfleet, Deltans must swear "an oath of celibacy" so as not to influence or take advantage of crewmembers. That is why Lt. Ilia stated that her "oath of celibacy" was on record.
