File:Complete Male Orgasm Process.ogv

English: Complete demonstration of the orgasm process of an adult male. The subject is a 27-year-old healthy circumcised Caucasian male. The video begins with the subject's genitals in a non-aroused flaccid state (0:00). As arousal progresses(0:30), the subject's penis becomes erect, the scrotum tightens and the testicles elevate. At the peak of arousal (0:57), orgasm occurs and semen is ejaculated from the penis in a series of rhythmic contractions. (In this demonstration, there are 15 strong contractions followed by 10 weaker contractions). Once arousal has peaked (1:35), the penis returns to its flaccid state, the scrotum loosens, and the testicles descend. Please note that the arousal/orgasm process can take anywhere from a few seconds to several hours, and this video is intended to demonstrate the typical process, not the typical duration (see an alternate example here).
