postcoital

Postcoital, from Latin post coitum, describes phenomena occurring after sexual intercourse. It is used as an adjective to describe physical states, physiological responses, or psychological experiences that follow sex. The postcoital period can vary in duration and intensity between individuals and contexts, and it can involve humans or other animals.

Physiologically, the immediate postcoital phase is a transition from arousal to recovery. Hormonal changes after orgasm include the release of prolactin and oxytocin, which are associated with relaxation, sexual satiation, bonding, and sleepiness. Heart rate and blood pressure generally decline toward baseline, respiration slows, and some people experience warmth, tingling, or tenderness in the genital region.

Psychological experiences vary widely. Many individuals report contentment, closeness, or relaxation in the postcoital period. Others may experience postcoital tristesse (PCT), a transient mood change such as sadness, anxiety, or irritability after sex. PCT is relatively uncommon and its causes are not fully understood, though hormonal fluctuations, sleep disruption, fatigue, and relationship dynamics are thought to contribute.

Clinical and health considerations include postcoital bleeding, which requires evaluation if persistent or heavy, as it can signal cervical irritation, infection, polyps, trauma, or other medical conditions. Postcoital headaches or chest pain, though rare, also warrant medical assessment. Less urgent but relevant are sleep quality and sexual satisfaction in the context of overall well-being and relationships.

In cultural and clinical contexts, discussions of the postcoital period can support sexual health education, consent, and partner communication. Some couples prioritize cuddling or resting after sex to support emotional bonding and sleep.
