The human penis is an external male intromittent organ that additionally serves as the urinal duct.
- The womb is a part peculiar to the female; and the penis is peculiar to the male. This latter organ is external and situated at the extremity of the trunk; it is composed of two separate parts: of which the extreme part is fleshy, hardly alters in size, and is called the glans; and round about it is a skin devoid of any specific title, which never grows together again if it is cut any more than does the jaw or the eyelid. And the connexion between the latter and the glans is called the frenum. The remaining part of the penis is composed of gristle; it is easily susceptible of enlargement; and it protrudes and recedes in the opposite way to that of the cat. Underneath the penis are two testicles, and the integument of these is a skin that is termed the scrotum.

- He mounted and reclined on the nearer side, his swollen penis harder than horn, and meanwhile pulling up the bottom edge of the garment; there he met legs that bristled with thick rough hair.
- Ovid, Fausti
- For a time the wine circulated among them and the porter then got up, undressed and went into the pool. The girls looked at him swimming in the water and washing under his beard and beneath his armpits, as they had done. Then he came out and threw himself into the lap of the lady of the house, with his arms in the lap of the doorkeeper and his feet and legs in the lap of the girl who had bought the provisions. Then he pointed to his penis and said: ‘Ladies, what is the name of this?’ They all laughed at this until they fell over backwards. ‘Your zubb,’ one of them suggested. ‘No,’ he said, and he bit each of them. ‘Your air,’ they said, but he repeated ‘No’, and embraced each of them.
Morning now dawned and Shahrazad broke off from what she had been allowed to say. Then, when it was the tenth night, her sister Dunyazad said: ‘Finish your story.’ ‘With pleasure,’ she replied, and she continued: I have heard, O fortunate king, that the girls produced three names for the porter, while he kissed, bit and embraced them until he was satisfied. They went on laughing until they said: ‘What is its name, then, brother?’ ‘Don’t you know?’ ‘No.’ ‘This is the mule that breaks barriers, browses on the mint of the dykes, eats the husked sesame and that passes the night in the khan of Abu Mansur.’ The girls laughed until they fell over backwards and then they continued with their drinking party, carrying on until nightfall.

- We as mammals see the sexes defined by whole syndromes of characteristics—possession of a penis, bearing of the young, suckling by means of special milk glands, certain chromosomal features, and so on. These criteria for judging the sex of an individual are all very well for mammals but, for animals and plants generally, they are no more reliable than is the tendency to wear trousers as a criterion for judging human sex. In frogs, for instance, neither sex has a penis.
