It seems that this is also true for howler monkeys, which broadcast their presence across the rainforests of South America with deep hollering vocalizations. But their voices could be telling us a little more about the males than they might want to let on. New research has found that the deeper the male's call, the smaller his balls.

“We have been interested for quite some time about the vocalizations howler monkeys make,” University of Utah’s Leslie Knapp explained to IFLScience. “Because if you go to the field, and study these primates in Mexico or other parts of central or South America, you can’t help but notice the loudness of the calls.” What they found was that the species of howler monkeys who had the loudest and deepest calls, also had the smallest testes, and vice versa....
