As of 2015 [update], a systematic review of 15,521 men, who were measured by health professionals rather than themselves, concluded that the average length of an erect human penis is 13.12cm (5.17 inches) long, while the average circumference of an erect human penis is 11.66cm (4.59 inches).

Willingham explains that this violent process has caused bedbugs to evolve “something very vagina-like where they tend to get stabbed.” This special less-armored area of their abdomen might minimize harm as the male injects his sperm into the female’s circulatory system.

The penis in most male Coleoid cephalopods is a long and muscular end of the gonoduct used to transfer spermatophores to a modified arm called a hectocotylus. That, in turn, is used to transfer the spermatophores to the female. In species where the hectocotylus is missing, the penis is long and able to extend beyond the mantle cavity and transfers the spermatophores directly to the female. Deepwater squid have the greatest known penis length relative to body size of all mobile animals, second in the entire animal kingdom only to certain sessile barnacles Penis elongation in Onykia ingens may result in a penis that is as long as the mantle, head and arms combined. [145] [146] Giant squid of the genus Architeuthis are unusual in that they possess both a large penis and modified arm tips, although it is uncertain whether the latter are used for spermatophore transfer. [145] Etymology Raccoons have penis bones which bend at a 90 degree angle at the tip. [80] The extrusibility of a raccoon's penis can be used to distinguish mature males from immature males. [81] [82] In male insects, the structure analogous to a penis is known as aedeagus. The male copulatory organ of various lower invertebrate animals is often called the cirrus. [141]

In Transandinomys talamancae, the outer surface of the penis is mostly covered by small spines, but there is a broad band of nonspinous tissue. [96] Leonard Lee Rue III (2004).

Male cetaceans (whales, dolphins, and porpoises) have two slits, the genital groove concealing the penis and one further behind for the anus. [46] [47] [48] [49] Cetaceans have fibroelastic penises, similar to those of Artiodactyla. [50] The tapering tip of the cetacean penis is called the pars intrapraeputialis or terminal cone. [51] The blue whale has the largest penis of any organism on the planet, typically measuring 2.4–3.0m (8–10ft). [52] Accurate measurements are difficult to take because its erect length can only be observed during mating, [53] which occurs underwater. The penis on a right whale can be up to 2.7m (8.9ft) – the testes, at up to 2m (6ft 7in) in length, 78cm (2ft 7in) in diameter, and weighing up to 238kg (525lb), are also by far the largest of any animal on Earth.

Flatworms are hermaphrodites, meaning they have both male and female sex organs, which triggers some seriously odd reproductive behavior. When trying to impregnate another worm, for example, a flatworm tries to pierce the skin of the other using its penis. Experts term this heated competition " penis fencing": The first to successfully impregnate the other while fending off advances becomes the de facto male, who wins because he won't have to expend the energy required to carry eggs. a b Anderson, MJ (1998).
