Unlike the female orgasm, where a number of competing descriptions for induced orgasms exist (see Levin, 2015), those for the male are limited (Zilbergeld, 1979; Otto, 1999). Surprisingly, neither Masters and Johnson (1966), Zilbergeld (1979), Margolis (2004), or Bancroft (2009) in their books on human sexual arousal mention those obtained from prostate stimulation in the male while even in the book on orgasm by Komisaruk et al. (2006) has only a single, very short paragraph of but two sentences.
The classic penile‐induced male orgasm description is that of Masters and Johnson (1966) who characterized it into two separate stages. The first stage is initiated by the contractions of the various accessory organs beginning with the vasa efferentia of the testis, then the epididymis following through to the vas deferens with the contractions of the seminal vesicles. The prostatic contractions then occur. This stage is controlled by the thoracolumbar (T11‐L2) neural pathway (Giuliano and Clement, 2005). In this stage the male has a feeling of ‘ejaculatory inevitability’ and the knowledge that ejaculation is coming and cannot be delayed. The second stage is the seminal fluid flowing into the distended urethral bulb and the penile urethra. The perineal musculature (mainly the bulbocavernosus muscle, Levin, 2005) then propels the semen along the penile urethra to be expelled forcibly in spurts from the penile meatus, this is mediated by the sacral (S2‐S4) pathway (Giuliano and Clement, 2005). With each spurt a feeling of intense pleasure is generated which gradually subsides as the spurts decrease. Often nonverbal vocalizations occur with each spurt (Levin, 2006). If the pelvic muscles do not contract the semen emission is one of dribbling, powered by the peristaltic contractions of the urethra alone with little ecstatic pleasure (Newman et al., 1982). Although orgasm normally takes place concomitantly with ejaculation, the two processes are actually independent (Levin, 2003).While the prostate is involved in forming part of the ejaculate (as detailed above) it is also involved in ejaculation per se as its fibromuscular covering containing smooth muscle contracts clonically under its adrenergic innervation propelling the semen from the prostatic urethra into the penile urethra (White et al., 2013).
Published descriptions of the prostate‐induced orgasm in academic and clinical literature have been thin on the ground (Levin, 2004). In an early article by Perry (1988) he described prostatic‐induced orgasms as ‘emission type reflexive orgasms’ with occasional oozing of semen from the penis. Such a description applies to ejaculations that occur when the pelvic striated muscles (especially the bulbocavernous) are nonfunctional (Newman et al., 1982). A paradox to note is that when induced ejaculations are without pelvic contractions they are of poor erotic value as previously described yet intense eroti
