Coming in at just 1.1 inches (3 centimeters) long, on average, the penis of the adult male gorilla (Gorilla) is the smallest phallus of all apes. The gorilla's genital size comes with other deficits in its reproductive capacity, such as low sperm count compared to other primates, and sperm with poor motility and a diminished ability to bind to eggs.
Given that these are reproductive issues that can also affect humans, it may seem surprising that all male gorillas share these traits. However, this can be explained by gorillas' mating system, said Jacob Bowman, lead author of the new study and a postdoctoral researcher at the University at Buffalo.
