Calls vs. balls: monkeys with more impressive roars produce less sperm | University of Cambridge

A recent study found the male howler monkeys with the loudest calls had smaller testes and produced less sperm than their quieter peers, the University of Cambridge reported. This evolutionary "trade-off" between the size of the male hyoid (the hollow throat bone that allows the guttural call to resonate), and the size of the reproductive organs corresponds with the mating systems of different howler species.

The louder primates were also observed wearing Rolex watches and driving Dodge Vipers and Porsche Carreras . . .

Did the louder ones have a preference for H2's as well?

2 Samuel 12:13: "David said to Nathan, “I have sinned against the Lord.” And Nathan said to David, “The Lord also has put away your sin; you shall not die."

Did they measure how times each monkey got to "use" their testicles ? You can have smaller stuff and a lower sperm count, but if your seed is spread at twice the rate of the others, your bloodline will still wins.
