the set of physiological and emotional changes that lead to and follow orgasm. There are various models of the phases of the sex response cycle. Usually, these models include three, four, or five distinct phases. The four phases model includes :
  • excitement - can last for just a few minutes or extend for several hours. Characteristics of this phase include : an increasing level of muscle tension, a quickened heart rate, flushed skin, the onset of vasocongestion. Additional changes in women include hardened or erect nipples and the enlarge of breasts, swelling of the clitoris and labia minora, the vaginal walls begin to produce a lubricating liquid, the uterus elevates and grows in size, vagina swells and the muscle that surrounds the vaginal opening, called the pubococygeal muscle, grows tighter. In men the urinary bladder closes to block the possibility of urine mixing with the semen.Additional changes in men include elevation and swelling of the testicles and erection of the penis, tightening of the scrotal sac, and secretion of a lubricating liquid by the Cowper's glands
  • plateau - characterized primarily by the intensification of all of the changes begun during the excitement phase. During plateau phase, the woman's clitoris may become so sensitive that it is painful to the touch. The plateau phase extends to the brink of orgasm, which initiates the reversal of all of the changes begun during the excitement phase.
  • orgasm - the peak of sexual excitement. Characteristics of this phase include : involuntary body muscle contractions, heightened blood pressure and heart rate, rapid intake of oxygen, sphincter muscle contraction, and sudden forceful release of sexual tension. For men, orgasm generally ends in the ejaculation of semen. For women, orgasm also consists of rhythmic muscle contractions of the uterus
  • resolution - the body returns to normal levels of heart rate, blood pressure, breathing, and muscle contraction. Swelled and erect body parts return to normal and skin flushing disappears. The resolution phase is marked by a general sense of well being and enhanced intimacy and possibly by fatigue as well. Males, especially as they age, experience a refractory period of varying duration after orgasm. Many women are capable of a rapid return to the orgasmic phase with minimal stimulation and may experience continued orgasms for up to an hour

main part of a penis.
the flexible tissue forming the external natural protective covering of the body, serving vital protective and metabolic functions of the body. It contains two main layers of cells :
  • epidermis - a thin outer layer where young cells continuously multiply, the older cells gradually shedding as calluses or collections of dead skin. Contains in its deeper strata melanin, the pigment that gives color to the skin
  • dermis - a thicker inner layer contains connective tissue in which are embedded blood vessels, lymph channels, nerve endings, sweat glands, sebaceous glands, fat cells, hair follicles, and muscles
The skin provides a barrier against invasion by outside organisms and protects underlying tissues and organs from abrasion and other injury, its pigments shield the body from the dangerous ultraviolet rays in sunlight, waterproofs the body, preventing excessive loss or gain of bodily moisture, its numerous sweat glands excrete waste products along with salt-laden moisture, the evaporation cooling of the body, its fat cells act as insulation against cold and produce the D vitamin. Skin has self-healing properties - injuries of the dermis or deeper wounds, penetrating to the underlying tissue, heal by scar formation. Skin can be donated and transplanted.
sample, as of blood or bacterial cells, spread on a slide for microscopic examination or on the surface of a culture medium. Used for diagnosis in cervix dysplasia, condyloma or the health of vagina.

Smegma can be removed by wiping or washing the genital area.

The chancre lasts 3 to 6 weeks, and it heals without treatment but the infection will progresses if adequate treatment is not administered
  • secondary stage - characterized by skin rash and mucous membrane lesions on one or more areas of the body appearing as the chancre is healing or several weeks after the chancre has healed. Also might appear fever, swollen lymph glands, sore throat, patchy hair loss, headaches, weight loss, muscle aches, and fatigue. The symptoms may resolve without treatment, but the infection will progress
  • third (or late) stage - begins when secondary symptoms disappear. Symptoms of the third stage may include difficulty coordinating muscle movements, paralysis, numbness, gradual blindness, and dementia as the infection attacks the brain, nerves, eyes, heart, liver, bones, and joints
