what is the meaning of orgasm?

Orgasm (from Greek οργασμός orgasmos, from organ to mature, swell, also sexual climax) is the sudden discharge of accumulated sexual tension during the sexual response cycle, resulting in rhythmic muscular contractions in the pelvic region characterized by sexual pleasure.[1][2][3] Experienced by males and females, orgasms are controlled by the involuntary or autonomic nervous system. 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 are expressed.[2] The period after orgasm (known as a refractory period) is often a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin, as well as endorphins (or "endogenous morphine").[4]

Human orgasms usually result from physical sexual stimulation of the penis in males (typically accompanying ejaculation), and the clitoris in females.[2][5][6] Sexual stimulation can be by self-practice (masturbation) or with a sex partner (penetrative sexual intercourse, non-penetrative sex, or other erotic sexual activity).

Health effects concerning human orgasm range from general aspects such as the physiological responses during the sexual response cycle, effects on the brain such as a temporary decrease in the metabolic activity of large parts of the cerebral cortex and normal or increased metabolic activity in the limbic areas of the brain,[7] general health benefits such as the relaxed state created by prolactin, and sexual dysfunctions such as anorgasmia. These effects impact cultural views of orgasm, such as the belief that orgasm and the frequency/consistency of it are important or irrelevant for satisfaction in a sexual relationship,[8] and theories about the biological and evolutionary functions of orgasm.[9][10]

Orgasm in non-human animals has been studied significantly less than orgasm in humans, but research on the subject is ongoing.

It's the sexual climax.
