ERECTION [INTRO]

{Intro}
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, sexual attraction or libido, although erections can also be spontaneous
The shape, anglе, and direction of an erection vary considеrably between humans
Physiologically, an erection is required for a male to effect penetration or sexual intercourse and 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
Physiologically, an erection is required for a male to effect penetration or sexual intercourse and 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
Erections during sleep or upon waking up are known as nocturnal penile tumescence (NPT), also known as "morning wood". Absence of nocturnal erection is commonly used to distinguish between physical and psychological causes of erectile dysfunction and impotence
The state of a penis which is partly, but not fully, erect is sometimes known as semi-erection (clinically: partial tumescence); a penis which is not erect is typically referred to as being flaccid, or soft
