Multiple Orgasms in Men—What We Know So Far

IntroductionThere is much popular discussion on strategies to facilitate multiple orgasms in men (ie, 100,000+ hits in Google), yet the topic has not received an objective comprehensive review in the literature.AimTo review the literature on male multiple orgasms.MethodsWe searched the literature for publications on “male multiple orgasms” and factors influencing male multiple orgasms in Google, PubMed, and PsychINFO. This yielded 15 relevant publications.Main Outcome MeasuresA comprehensive overview on the topic of male multiple orgasms and factors that influence the propensity of men to experience multiple orgasms.ResultsFew men are multiorgasmic: <10% for those in their 20s, and <7% after the age of 30. The literature suggests 2 types of male multiple orgasms: “sporadic” multiorgasms, with interorgasmic intervals of several minutes, and “condensed” multiorgasms, with bursts of 2–4 orgasms within a few seconds to 2 minutes. Multiple orgasms appear physiologically similar to the single orgasm in mono-orgasmic men. However, in a single case study, a multiorgasmic man did not experience with his first orgasm the prolactin surge that usually occurs with orgasm in mono-orgasmic men. Various factors may facilitate multiple orgasms: (1) practicing to have an orgasm without ejaculation; (2) using psychostimulant drugs; (3) having multiple and/or novel sexual partners; or (4) using sex toys to enhance tactile stimulation. However, confirmatory physiological data on any of these factors are few. In some cases, the ability to experience multiple orgasms may increase after medical procedures that reduce ejaculation (eg, prostatectomy or castration), but what factor(s) influence this phenomenon is poorly investigated.ConclusionDespite popular interest, the topic of male multiple orgasms has received surprisingly little scientific assessment. The role of ejaculation and physiological change during the refractory period in inhibiting multiple orgasms has barely been investigated.
