Human penis
Human male external reproductive organ
In human anatomy, the penis (pl.: penises or penes; from the Latin pēnis, initially 'tail') is an external sex organ (intromittent 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 main parts of the penis are the root, body, the epithelium, including the shaft skin, and the foreskin covering the glans.
