How It Occur

Male sexuality begins with interest and desire. Next is the state of arousal, which results from various combinations of erotic thoughts and sensory stimulation. The impulse of desire is transmitted from nerves in the pelvis to the arteries in the penis, which widen to admit more blood and produce a rigid erection.

The next stage is ejaculation which is quiet complex. It begins with emission, a brief phase that momentarily precedes ejaculation itself. Emission is triggered by the autonomic nervous system, specifically by the fibers that originate between the lower thoracic (T10-12) and upper lumber (L1 and L2) segments of the spinal cords. These nerves cause muscles in the prostate to contract, propelling prostate secretions in the urethra. Immediately thereafter, muscles in the vas deferens and seminal vesicles spring into action, expelling semen into the urethra. The muscles of the neck of the bladder close, preventing semen from entering the bladder. Simultaneously, muscles in the penis and pelvis begin a series of rhythmic contractions that forcefully expel the semen forward through the urethra, and then out from the penis.

Ejaculation is usually accomplished by the pleasurable sensation of orgasm which is followed by detumescence. When the arteries in the penis become narrow and the veins widen, blood drains from the penis and returns into its flaccid state.

The sex act is instinctive and automatic, but it depends on the complex interaction of psychological functions, the nervous system, blood vessels and the genital tract itself. Problem at any stage of this complex process of ejaculation may result in abnormal ejaculation, mainly as premature ejaculation.
