Penile sheath
Non-human mammal foreskin
From Wikipedia, the free encyclopedia
Almost all mammal penises have prepuces.[1][2] In non-human mammals, the prepuce is sometimes called the penile sheath[3] or preputial sheath.[4]
In koalas, the foreskin contains naturally occurring bacteria that play an important role in fertilization.[5] In some bat species, the prepuce contains an erectile tissue structure called the accessory corpus cavernosum.[6]
During musth, a male elephant may urinate with the penis still in the sheath, which causes the urine to spray on the hind legs.[7]
Male dogs and wild dogs have a large and conspicuous penile sheath.[8]
In stallions, the retractor penis muscle contracts to retract the stallion's penis into the sheath and relaxes to allow the penis to extend from the sheath.[9]
The penile sheath of a male axis deer is elongated and urine-stained. When rubbing trees with their antlers, these stags sometimes move the penis back and forth rapidly inside its sheath.[10] Male bison and fallow deer have tufts of fur at the end of their penile sheaths.[11]
In rodents, the length of the prepuce is related to urine marking behavior.[12]
