Human penis

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, angle, and direction of an erection vary considerably between humans.

In human anatomy, the penis is an external sex organ through which males ejaculate and urinate. Together with the testes and surrounding structures, the penis functions as part of the male reproductive system.

The koteka is held in place by a small loop of fiber attached to the base of the koteka and placed around the scrotum.
