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