Why does the gorilla have a small penis?
The gorilla doesn’t need a super-sized penis (it measures just three centimeters), but rather a strong body to dominate its rivals.
Gorillas are 1.80 meters tall, can weigh up to 200 kilograms, and are four to ten times stronger than a well-trained man, able to bring down a banana tree without much effort. Yet, they have the smallest penis of all primates, just three centimeters (smaller than a human newborn’s, for comparison); their testicles are small too, and their sperm is often scarce, abnormal, and even “lazy,” with low motility.
Alpha male. This setback is due to the social organization of gorillas, who live in highly hierarchical communities where only one male mates with all the females in the group: to dominate the rivals, a gorilla needs a big, strong body, rather than an oversized penis. By the time mating happens, the rivals have already been eliminated, so he doesn’t need to be super-endowed to ensure he has offspring.
Size comparison. For confirmation, just look at the attributes of chimpanzees, who live in groups with many males, where females mate with several of them: their testicles are three times larger than their brains, capable of producing vast amounts of sperm multiple times a day, with very “competitive” sperm that can survive up to four days after ejaculation.
