Scientists Discover Genetic Mutation Behind Gorillas' Small Penises

Scientists from the University of Buffalo have identified a genetic mutation responsible for the small penises of male gorillas, which measure just 1.1 inches on average. This adaptation is linked to their polygynous mating system, where the alpha male's physical dominance reduces sperm competition. The study also suggests that these genetic findings could help explain certain cases of male infertility in humans, as similar mutations were found in genes linked to reproductive function.
