In a study published in the September issue of the Proceedings of the Royal Society B , a team of scientists began their study by investigating the sex lives of animals that have a penis bone, technically called a baculum. Another, somewhat colourfully named, theory is the vaginal friction hypothesis. So I brought the equal and oosiks together. The oosik is a polished and sometimes carved baculum of these large northern carnivores. Filters Sort by relevance Sort by recent Sort by oldest.

Depending on the animal, bacula range in size from under a millimetre to nearly a metre long, and in shape, varying from needle-like spines to fork like prongs. A penis bone baculum, os priapi is present in various degrees of development in many mammals. But bonobos only copulate for about 15 seconds at a time and they still have a baculum, even if it is very small about 8mm. The team came to this conclusion after creating 3D models of different baculums and virtually crash-testing them into virtual vaginas.
