The female orgasm
The female orgasm
The following description of the physiological process of female orgasm in the genitals will use the Masters and Johnson four-phase model.
Excitement
When a woman is stimulated physically or psychologically, the blood vessels within her genitals dilate. Increased blood supply causes the vulva to swell, and fluid to pass through the vaginal walls, making the vulva swollen and wet. Internally, the top of the vagina expands.
Heart rate and breathing quicken and blood pressureincreases. Blood vessel dilation can lead to the woman appearing flushed, particularly on the neck and chest.
Plateau
As blood flow to the introitus - the lower area of the vagina - reaches its limit, it becomes firm. Breasts can increase in size by as much as 25 percent and increased blood flow to the areola - the area surrounding the nipple - causes the nipples to appear less erect. The clitoris pulls back against the pubic bone, seemingly disappearing.
Orgasm
The genital muscles, including the uterus and introitus, experience rhythmic contractions around 0.8 seconds apart. The female orgasm typically lasts longer than the male at an average of around 13-51 seconds.
Unlike men, most women do not have a refractory (recovery) period and so can have further orgasms if they are stimulated again.
Resolution
The body gradually returns to its former state, with swelling reduction and the slowing of pulse and breathing.
The male orgasm
The following description of the physiological process of male orgasm in the genitals uses the Masters and Johnson four-phase model.
Excitement
When a man is stimulated physically or psychologically, he gets an erection. Blood flows into the corpora - the spongy tissue running the length of the penis - causing the penis to grow in size and become rigid. The testicles are drawn up toward the body as the scrotum tightens.
Plateau
As the blood vessels in and around the penis fill with blood, the glans and testicles increase in size. In addition, thigh and buttock muscles tense, blood pressure rises, the pulse quickens, and the rate of breathing increases.
Orgasm
Semen - a mixture of sperm (5 percent) and fluid (95 percent) - is forced into the urethra by a series of contractions in the pelvic floor muscles, prostate gland, seminal vesicles, and the vas deferens.
Contractions in the pelvic floor muscles and prostate gland also cause the semen to be forced out of the penis in a process called ejaculation. The average male orgasm lasts for 10-30 seconds.
Resolution
The man now enters a temporary recovery phase where further orgasms are not possible. This is known as the refractory period, and its length varies from person to person. It can last from a few minutes to a few days, and this period generally grows longer as the man ages.
During this phase, the man's penis and testicles return to their original size. The rate of breathing will be heavy and fast, and the pulse will be fast.
Causes
It is commonly held that orgasms are a sexual experience, typically experienced as part of a sexual response cycle. They often occur following the continual stimulation of erogenous zones, such as the genitals, anus, nipples, and perineum.
Physiologically, orgasms occur following two basic responses to continual stimulation:
Vasocongestion: the process whereby body tissues fill up with blood, swelling in size as a result.Myotonia: the process whereby muscles tense, including both voluntary flexing and involuntary contracting.
There have been other reports of people experiencing orgasmic sensations at the onset of epileptic medicine, and foot amputees feeling orgasms in the space where their foot once was. People paralyzed from the waist down have also been able to have orgasms, suggesting that it is the central nervous system rather than the genitals that is key to experiencing orgasms.
