Mechanism of Ejaculation

A lot of people worry about having developed premature ejaculation, and many of them don’t really have it at all. So let me clear this misconception once and for all. Porn isn’t bad at all, except when you start using it as a sex education class! Pornography is a source of entertainment, and just like any film, it is also a work of fiction. No normal, healthy male can last the 30-40 mins. you see in porn without ejaculating at least once. In fact, the average length of a sex act is 7.3 minutes, but 43 percent of men finish in under two minutes. So let’s go behind the scenes of the male climax:

Ejaculation is controlled by the central nervous system. When men are sexually stimulated, signals are sent to your spinal cord and brain from all your senses. Now when men reach a certain level of sexual excitement, signals are then sent from your brain to your penis. This transfer of information through nerves is what us doctors call the reflex arc. This reflex arc causes semen to be released through the penis, which is called ejaculation.

Ejaculation has 2 phases: Emission and Expulsion


Phase 1: Emission

Emission is when sperm moves from the testicles to the prostate, and this is the semen factory where sperm is mixed with a bunch of other stuff to make semen. The semen then moves from the prostate to the base of the penis. This is through tubes that are called vas deferentia.

Phase 2: Expulsion or Discharge

Expulsion is when the muscles at the base of the penis contract; pelvic floor muscles. This forces semen out of the penis. Usually, ejaculation and orgasm (climax) happen at the same time. In most cases, erections go away after this step. Yes, remember this point. If anyone’s telling you they can go on after orgasming, they’re lying. It’s not biologically possible.

Definition of Premature Ejaculation Let’s now define premature ejaculation, and see what the medical books say. Premature ejaculation effects up to 30% of the male population, and is the most common sexual disorder in men.

The International Society of Sexual Medicine defines premature ejaculation under 3 headings:

  1. Ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration from the first sexual experience (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE; caused by medical, psychological reasons)

  2. The inability to delay ejaculation on all or nearly all vaginal penetrations

  3. Negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy
