Document Summary

Sexual response cycle: william masters and virginia johnson, provided one of the first models of physiology of human sexual response: human sexual response in. Men: beginning of erotic arousal, physiological process, vasocongestion procures obvious arousal response in men-erection. It occurs rapidly (in young men, within seconds). It depends on age, alcohol intake, and fatigue: erection results when corpora cavernosa and the corpus spongiosum fill with blood. Scrotal sac tenses, and scrotum is pulled up and closer to the body: spermatic cords shorten, pulling the testes closer to the body. Late in the excitement phase, elevation of the clitoris may occur. It retracts or draws up into the body crura of the clitoris and the vestibular bulbs occurs, allowing a great deal of blood flow to the region: estrogen helps the vasodilation. In unaroused state, the inner lips are generally folded over, covering the entrance to the vagina, and outer lips lie close to each other.
