The third and shortest phase of the sexual cycle is the orgasmic phase. Once a man has reached this phase there is no way of stopping. Come what may, he is going to ejaculate. Although the higher brain centres are involved in orgasm, no voluntary control can prevent a man from ejaculating once he has reached this stage, so that orgasm resembles a reflex.
The first part of the orgasmic phase is one which lasts less than 3 seconds, during which the man knows that he is going to ejaculate. Inside his genital tract, his prostate gland, and perhaps his seminal vesicles, have begun to contract, forcing seminal fluid into the deepest part of his urethra, which stretches to accommodate the 2 to 5 ml of seminal fluid and the added secretions from his prostate gland. At the same time the entrance from the urethra to the bladder has been closed, so that the seminal fluid cannot escape backwards into it.
