The term erection is most often used to refer to an erection of the penis. It is widely believed that a man's penis needs to be erect in order for him to take part in sexual intercourse and penetrate his partner's vagina and to ejaculate semen , but all are possible without an erection. In a healthy male, an erection will usually occur if the man is sexually aroused made sexually excited or stimulated. This can happen if he is touched sexually, or even if he is not touched — for example, if he sees a naked person or thinks about having sex with someone else.

An erection clinically: penile erection or penile tumescence is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal or sexual attraction , although erections can also be spontaneous. The shape, angle, and direction of an erection varies considerably in humans. Physiologically, erection is triggered by the parasympathetic division of the autonomic nervous system , causing the levels of nitric oxide a vasodilator to rise in the trabecular arteries and smooth muscle of the penis. The arteries dilate causing the corpora cavernosa of the penis and to a lesser extent the corpus spongiosum to fill with blood ; simultaneously the ischiocavernosus and bulbospongiosus muscles compress the veins of the corpora cavernosa restricting the egress and circulation of this blood. Erection subsides when parasympathetic activity reduces to baseline. As an autonomic nervous system response, an erection may result from a variety of stimuli, including sexual stimulation and sexual arousal , and is therefore not entirely under conscious control.
