Previous data have indicated that orgasm produces marked alterations in plasma prolactin concentrations in men and women. Thus, the current study aimed to extend these data by examining prolactin response to coitus in healthy males and females. Ten pairs of healthy heterosexual couples participated in the study. Blood was drawn continuously for 20 min before, during, and until 60 min following sexual intercourse and orgasm. Plasma was subsequently analysed for prolactin concentrations. Coitus-induced orgasm produced a marked elevation of plasma prolactin in both males and females. Plasma prolactin concentrations remained elevated 1 h following orgasm. These data, together with previous evidence that masturbation-induced orgasm produces pronounced, long-lasting increases in plasma prolactin concentrations in both males and females, suggest a role for acute prolactin alterations in modifying human sexual desire following orgasm.
