Studies have shown that the longer a male's phallus is, the more elaborate the vaginal structures were. This reduced the likelihood of fertilization by unwanted aggressors in favor of fitter mates.

Females have a small phallic organ in the cloaca which becomes larger during the breeding season. External male genitalia of a Labrador Retriever As with any other bodily attribute, gorilla pénisz hossza length and girth of the penis can be highly variable between mammals of different species. A bone called the baculum or os penis is present in most mammals but absent in humans, cattle and horses.

In mammals the penis is divided into three parts: [15] Roots crura : these begin at the caudal border of the pelvic ischial arch.

Body : the part of the penis extending from the roots. Glans : the free end of the penis. The internal structures of the penis consist mainly of cavernous, erectile tissuewhich is a collection of blood sinusoids separated by sheets of connective tissue trabeculae.

The urethra is on the ventral side of the body of the penis. As a general rule, a mammal's penis is proportional to its body size, but this varies greatly between species — even between closely related ones. For example, an adult gorilla 's erect penis is about 4.

The barnacle's penis can grow to up to forty times its own body length. This enables them to reach the nearest female for fertilization. A number of invertebrate species have independently evolved the mating technique of traumatic insemination where the penis penetrates gorilla pénisz hossza female's abdomen, thereby creating a womb into which it deposits sperm. This has been most fully studied in bed bugs. Some millipedes have penises.

In these species, the penis is simply one or two projections on underneath the third body segment that produce a spermatophore or sperm packet.
