by itself
Clarification:
Sperm is in the semen, which is ejaculated when sexual climax is reached.
Males can make sperm come out, its usually called masturbation when they do it to themselves, alone. Sometimes, particularly in the early teens, sperm can come out during sleep, which would fit the description of "by itself" since it's not intentionally. Usually though, it takes some sort of deliberate act to release sperm, sexual stimulation of some sort. And since it's a deliberate act I guess you could say it's "made" to come out. A male might not be able to decide EXACTLY when, but he should know fairly well that it's about to happen.
