Orgasm

Orgasm is a brief climax of sexual arousal marked by intense pleasure and often rhythmic, involuntary muscular contractions. Its sensations and bodily signs vary among individuals and contexts.

Sexual response cycle: A model of recurring bodily and psychological changes during sexual activity. Orgasm is commonly described as the climax phase of this broader response.
Sexual arousal: A psychological and physiological state of increased sexual interest and bodily response. Arousal can lead to orgasm but does not necessarily culminate in it.
Clitoral orgasm: An orgasm associated with stimulation of the clitoris and its connected erectile structures. It is a commonly described pattern, though orgasm experiences are not neatly divided into types.
Sex therapy: A form of psychotherapy addressing sexual concerns, relationships, and sexual functioning. Therapy can help address distress or difficulties involving orgasm.
Neuroimaging of orgasm: The study of brain activity during orgasm using methods such as functional magnetic resonance imaging. Imaging studies investigate which brain networks change during orgasm.
Autonomic nervous system: The nervous system that regulates involuntary functions such as heart rate and smooth-muscle activity. Autonomic activity shifts during orgasm and contributes to its bodily changes.
Erogenous zone: An area of the body whose stimulation can produce sexual pleasure or arousal. Stimulation of different erogenous zones can contribute to orgasm.
Prostate orgasm: An orgasm associated with stimulation of the prostate and surrounding tissues. It illustrates that orgasm can arise through stimulation beyond external genital touch.
Orgasmic disorder: A clinical diagnosis involving marked delay, infrequency, absence, or reduced intensity of orgasm with distress. It frames persistent, distressing orgasm difficulties as a health concern.
Orgasm and consciousness: The study of how conscious experience relates to brain and bodily events during orgasm. Intense subjective experiences remain difficult to map onto measurable physiology.
