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.
The sexual response cycle refers to the sequence of physical and emotional changes that occur as a person becomes sexually aroused and participates in sexually stimulating activities, including intercourse and masturbation. Knowing how your body responds during each phase of the cycle can enhance your relationship and help you pinpoint the cause of sexual dysfunction. It is not the only model of a sexual response cycle, but it is the best known one.
They are often associated with other 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.
An orgasm in the human female is a variable, transient peak sensation of intense pleasure, creating an altered state of consciousness, usually with an initiation accompanied by involuntary, rhythmic contractions of the pelvic striated circumvaginal musculature, often with concomitant uterine and anal contractions, and myotonia that resolves the sexually induced vasocongestion and myotonia, generally with an induction of well-being and contentment. Women's orgasms can be induced by erotic stimulation of a variety of genital and nongenital sites. As of yet, no definitive explanations for what triggers orgasm have emerged.
The male orgasm is a complex experience. The major function of the male orgasm is to ejaculate sperm, although not all men will ejaculate during an orgasm. Beyond delivering pleasure, the role of the female orgasm is less clear, although it may help move the sperm closer toward the ovum egg.
Climaxing may be the high point of sex for a good portion of the sexually active population, but for about 80 percent of women and 28 percent of men yes, they can have difficulty toothe orgasm remains elusive. To gather their information, the team of researchers from the Mayo Clinic and the Indiana University School of Medicine reviewed available literature on sexual anatomy and neuroanatomy in an effort to discover potential reasons for why men and women might fail to orgasm. For example, in patients with lifelong premature ejaculation, the sympathetic system is typically overactive, and the parasympathetic system is underactive.
Billy Crystal may have been shocked when Meg Ryan so effectively—and amusingly—faked an orgasm in a restaurant during the movie When Harry Met Sallybut surveys suggest only one-third of women are regularly fully aroused during intercourse. And although poor partner performance, psychological issues, or physiological shortfalls are often cited as the reason, two evolutionary biologists now offer a provocative new explanation. In a paper published today, they argue that female orgasm is an evolutionary holdover from an ancient system, seen in some other mammals, in which intercourse stimulated important hormonal surges that drive ovulation. And because those hormonal surges no longer confer a biological advantage, orgasms during intercourse may be lost in some women.
The clitoral orgasm is the most common. Vaginal orgasm means that a woman can reach orgasm without clitoral stimulation. Most often this is through vaginal penetration.
Orgasm is marked by a feeling of sudden and intense pleasure, an abrupt increase in pulse rate and blood pressureand 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.
