Howler Monkeys Have a Deep Voice or Big Balls But Not Both
Thursday, October 22, 2015 13:01
% of readers think this story is Fact. Add your two cents.
Howler monkeys have low sexy calls or big balls, but not both. While this research “has no practical application to human mate choice … some research has suggested that men with deep voices have more sex partners, and therefore more opportunities to reproduce. But another study showed lower sperm quality in deeper-voiced men.” Oh wouldn't it be nice if … or would it?
