Primatologists suggest that the size of the bonobo clitoris evolved due to its crucial role in social behaviors, such as reducing conflict and strengthening group bonds, which are often achieved through sexual activity.
The female bonobo’s clitoris is proportionally much larger than the human clitoris. Experts often note that its size is comparable to that of the male bonobo’s penis.
| Feature | Bonobo Clitoris Size | Human Clitoris Size |
| Size | Very prominent, about 1.5–2 cm long and 1–1.5 cm wide. | Only a small part (the tip) is visible, with an average diameter of about 0.5 cm. |

For comparison, the female bonobo’s clitoris is often described as having a prominent size and position similar to the male penis in small primates. This is in stark contrast to the human clitoris, which is largely hidden.
Therefore, visually, the bonobo clitoris appears more prominent and larger overall. This makes it easier for sexual stimulation, which plays a vital role in their social lives.
