The Baculum or bacula, also known as the penis bone, penile bone, os penis, os genitale, or os priapi, is a bone in the penis of many placental mammals.
The baculum or bacula present in the penises of some primates, such as the gorilla and the chimpanzee.
The baculum arises from primordial cells in soft tissues of the penis, and its formation is largely influenced by androgens. The bone lies above the urethra, and it aids sexual reproduction by maintaining stiffness during sexual penetration.
Our animal baculum’s are museum quality polyurethane resin castings created from real ethnically obtained specimens from museums.
