Bakulum - a bone in the penis - is necessary for safety to animals, mating which lasts especially long. The scientific work on this is published in the journal Proceedings of the Royal Society B, briefly about the study tells the site of the City University of Manchester.

Bakulum is characteristic of many species of mammals - from pinnipeds and predators to rodents and primates. However, it does not exist in all animals and varies greatly in shape and length. A person does not have such a bone.

In the new work, researchers from the UK conducted a 3D scan of more than 70 bones of animals of different types: snow leopard, tiger, badger, otter, ferret and many others.

Researchers came to the conclusion that the baculum provides the urethra with prolonged "vaginal friction". It is the urethra that participates in the delivery of sperm during fertilization.

It is curious that people who do not have bakulum, quite fit in this theory. Homo sapiens falls into the category of animals with a short intercourse. According to the previous study, on average, man's mating lasts 5.4 minutes (maximum - 44 minutes, minimum - 33 seconds).
