Absence of orgasm-induced prolactin secretion in a healthy multi-orgasmic male subject

.In several studies we have recently demonstrated that orgasm induces prolactin secretion in healthy males and females. This suggests that prolactin may form a feedback regulator of threfractory period following orgasm. To examine this position we investigated the prolactin response of a healthy multi-orgasmic male subject. Blood was drawn continuously during masturbation-induced orgasm. The prolactin response of the case-subject was compared with that of nine healthy adult men with a normal refractory period. The case-subject showed no prolactin response to three orgasms. Data from this multi-orgasmic subject support the hypothesized role of plasma prolactin in contributing to sexual-satiation mechanisms.

The experimental session was conducted as described previously.3 – 6 Briefly, whilst viewing a documentary film blood was drawn continuously from participants and divided into 10 min intervals. The film switched to erotic scenes after 20 min and again after 60 min, with subjects required to masturbate until orgasm at these times.
