The physiology of an orgasm

Cancer and Sexual Health pp Cite as. The human orgasm, although tantalizingly short, is perhaps the greatest bodily pleasure that most men and women can experience without recourse to drugs. It is a complex of subjective mental with physical body changes. Its pleasure can never be recalled exactly which is perhaps one of the reasons for desiring its repetition. It dissolves body boundaries and thus unites lovers in a unique manner. In men, because it normally routinely accompanies ejaculation, it has simply been regarded as the drive reward for attempting procreation, and in evolutionary terms, as a spur to distribute their genes as widely as possible.

What is orgasm? A model of sexual trance and climax via rhythmic entrainment

They are usually associated with involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation and, frequently, body movements and vocalizations. Human orgasms usually result from physical sexual stimulation of the penis in males typically accompanying ejaculation and of the clitoris in females. The health effects surrounding the human orgasm are diverse. There are many physiological responses during sexual activity, including a relaxed state created by prolactin, as well as changes in the central nervous system such as a temporary decrease in the metabolic activity of large parts of the cerebral cortex while there is no change or increased metabolic activity in the limbic i. In a clinical context, orgasm is usually defined strictly by the muscular contractions involved during sexual activity, along with the characteristic patterns of change in heart rate, blood pressure, and often respiration rate and depth. There is some debate whether certain types of sexual sensations should be accurately classified as orgasms, including female orgasms caused by G-spot stimulation alone, and the demonstration of extended or continuous orgasms lasting several minutes or even an hour.

Everything you need to know about orgasms

Orgasm is marked by a feeling of sudden and intense pleasure, an abrupt increase in pulse rate and blood pressure , and spasms of the pelvic muscles that cause contractions of the lower vagina in the female and contractions of the urethra and ejaculation by the male. Males and females are physiologically capable of experiencing orgasm from infancy, and children who engage in masturbation or sex play may achieve this sensation. Orgasm can occur while a person is asleep and dreaming, as well as from sexual intercourse or masturbation. Since the male responses are usually more rapidly induced, the male probably achieves orgasms more consistently during intercourse than does the female. Once the female attains an orgasm, however, she remains sexually excited longer and may experience several successive orgasms, whereas the male is ordinarily unable to experience a second orgasm except after a waiting period.
