The Downer Hormone

September 9, 2010

When we talk about MMO inevitably MRP (Male Refractory Period) comes to mind, because nature implanted this automatism into our system that seems to prevent any man from pursuing additional sexual climaxes after he experienced an orgasm and/or full-blown ejaculation.

A definition of MRP is: A temporary period of psychophysiologic erectile incompetence immediately following ejaculation during which a male cannot be sexually aroused. The duration of the refractory period may be minimal in teen years and longer in later years. (A Descriptive Dictionary & Atlas of Sexology (1995), Francoeur, Perper, Scherzer)

Yet many men (of any age) positively experience MMO, as shown in the previous post. How this is possible (although MRP is a given fact) is not very well researched at all (check out this link to a rare exception about the struggle to shed light on MMO). We do know – and this is the good news – that MMO can be learned! I will write more about it later in this blog.

We also know now what is responsible for MRP (the „implanted automatism“)! Research has been done in recent years, quote: Following orgasm, the hormone prolactin is released into the bloodstream in both men and women. The hormone makes us feel satiated by countering the effect of dopamine, which is released during sexual arousal. […] Since elevated levels of prolactin have been linked to erectile dysfunction, this may also explain why most men need a recovery period after sex. (From issue 2540 of New Scientist magazine, 22 February 2006, page 21)

A case study in 2002 compared prolactin blood levels of a man capable of MO and nine guys who experience MRP: These data demonstrate a clear absence of the orgasm-induced prolactin surge in a healthy male exhibiting multiple orgasms and short refractory period. This contrasted with control participants, who each displayed a regular refractory period and associated prolactin surge following orgasm. These data support the hypothesis that orgasm-induced prolactin secretion may be one mechanism regulating peripheral and central effectors of the refractory period. (International Journal of Impotence Research (2002) 14, 133-135) Download the paper with details of this study as a pdf-file here!

Further investigation revealed this: Surprisingly, after orgasm from sexual intercourse, the increase in blood prolactin levels is 400 per cent higher in both sexes compared with after orgasm from masturbation. (Biological Psychology, vol 71, p 312)

Common wisdom (and experience) indicates: In women there is not a true refractory period and women are typically capable of achieving multiple orgasm with further stimulation.

At this point some interesting conclusions can be drawn:

  • the hormone prolactin is apparently the bad guy in this mechanism
  • prolactin does affect erection, yet ejaculation (or climax) can be achieved with a soft (rather semi-erect) penis, as can be observed in the previous posts clip or here
  • lower levels of prolactin in the blood after climax from masturbation suggest a good chance to learn MMO thru solosexual efforts
  • as does the fact that women are generally capable to achieve MO „with further stimulation“, and I might add that a high level of arousal is definitely supporting both women´s and men´s efforts to reach MO.

I ought not close without mentioning a drug in favor of MMO, because it is able to reduce prolactin levels in the blood. I don´t like to promote any drugs or substances in relation to sexual activities, I much prefer a natural approach. Occasionally drugs (such as Viagra, to name one of the most well-known) are helping men to regain joy and fulfillment believed lost in their sex lives. But I don´t feel all to comfortable with a drug claiming to enhance orgasmic capacities, while you can achieve a like effect all by yourself the natural way!

However, here´s that information:
Cabergoline, which is marketed under the trade name of Dostinex, is used to treat Parkinson’s disease, to prevent women producing milk when they want to stop breast-feeding, and to lower prolactin levels in patients with a pituitary tumor. It is also sometimes used to help men with sexual dysfunction.
Perhaps the most remarkable aspect of carbergoline is that it has been found to substantially raise a man’s chances of sustaining multiple orgasms during sex.
It is cabergoline’s capacity to lower prolactin levels that makes it such a sexual wonder drug for men. Prolactin is a single-chain protein hormone, closely related to growth hormone, that stimulates the secretion of milk of women. The hormone also has the effect of reducing a man’s desire for more sex by preventing new erections.
