What happens in the body during human sexual arousal?

Sexual arousal involves coordinated physiological and psychological responses in preparation for or during sexual activity. These changes can be triggered by mental stimuli, physical touch, or hormonal fluctuations, and they manifest differently across male and female anatomies. The process can progress through various stages of the human sexual response cycle, potentially culminating in an orgasm, though physical changes can also occur without leading to further sexual activity.

What we know

• Sexual arousal describes the physiological and psychological responses that occur in preparation for sexual intercourse or when exposed to sexual stimuli. [1, 2]
• Male arousal leads to an erection, cremaster reflex, and pre-ejaculate. [2]
• Female arousal involves engorged sexual tissues in the nipples, clitoris, and vaginal walls, along with changes to the cervix and vaginal lubrication. [2]
• Physical stimuli like touch and internal hormonal fluctuations can influence sexual arousal. [2]

Still open

• Several scholars have criticized certain inaccuracies in the traditional four-stage human sexual response cycle model and formulated alternative models.
