Quizplus · Accepted Answer

Prolactin is the hormone that is released after orgasm, which creates feelings of contentment, relaxation, and sleepiness. Serotonin is also involved in regulating mood, but it is not specifically tied to sexual satisfaction. Estrogen and testosterone are both sex hormones, but they are not directly involved in the post-orgasmic experience.
