Sexual Response Cycle: Myotonia And Vasocongestion

The sexual response cycle describes the changes that occur in the body as men and women become sexually aroused, which divides into four phases: excitement, plateau, orgasm, and resolution. Vasocongestion and myotonia are what characterize the sexual response cycle. Vasocongestion causes erection of the penis and swelling of the area surrounding the vaginal opening. Myotonia (muscle tension) causes facial grimaces, spasms in the hands and feet, and then the spasms of orgasm. The first phase of the sexual response cycle is the excitement phase. Erection in the male, vaginal lubrication in the female (vasocongestion), muscle tension (myotonia), an increase in heart rate, and the erection of the nipples in both males and females are the characteristics of this phase. The plateau phase is the second phase of the sexual response cycle. During this phase, there are increases in vasocongestion, muscle tension, heart rate, and blood pressure in preparation for orgasm. The level of
During the resolution phase, the level of sexual arousal returns to the prearoused state. After a man has an orgasm, blood releases from the penis and testes. The erection disappears and the testes return to their normal size. Men also have a refractory period, which follows orgasm. This would occur before the resolution. Once this period passes, this allows men to become rearoused to orgasm and return to preplateau levels. Women do not have this period; therefore, they can become quickly rearoused to the point of repeating an orgasm if they desire and receive continued sexual stimulation. Orgasms in women also trigger the release of blood from enlarged areas. The nipples return to their normal size. The clitoris and vaginal barrel gradually shrink and return to their unaroused sizes. Blood pressure, heart rate, and breathing also return to their levels before arousal. Both partners may experience feelings such as relaxed and
