Some animals, however, do have bones in their boners, and a new study in the Proceedings of the Royal Society B offers a compelling explanation for the function of the penis bone, or baculumin those species, shedding some light on why humans have lost theirs. It is what it sounds like: Prolonged intromission refers to the amount of time a penis is in a vagina. More broadly, the stronger the baculum, the longer the intromission.
The penis has a very simple job to do: to maintain sufficient stiffness to enter an orifice during the mating, and to deliver sperm. That's it. Most mammals have a unique bone called baculum also penis bone, penile bone or os penis in their penis.

The distribution of acid phosphatase in the two structures seems to be identical, whereas the distribution of alkaline phosphatase in the os penis cartilage seems to differ from that in the mandibular condylar cartilage and, by this, from all other studied growth cartilages.

The baculum also penis bonepenile boneor os penisor os priapi  is a bone found in the penis of many placental mammals. It is absent in the human penisbut present in the penises of other primatessuch as the gorilla and chimpanzee. The homologue to the baculum in female mammals is known as the baubellum or os clitoridis — a bone in the clitoris.
Read on to find out what it is, what it's for, and why you might want to wear one around your neck. Most male mammals have penis bones, but no two species' are alike. They vary widely in shape and size.
