Science of Love, Sex, and Babies

A smart man is just sperm’s way of spreading more sperm

Posted in news by jenapincott on November 6, 2008

super_spermEvolutionary psychologist Geoffrey Miller, author of The Mating Mind and the famous stripper study described in BLONDES, recently found another interesting connection: smart men have better sperm.

Analyzing the data of 425 veterans who took IQ tests and submitted sperm samples, Miller found a statistically significant link between men’s IQ and their sperm quality (higher scorers had higher sperm count and motility). Miller is the biggest propagator of the theory that intelligence is a sexually selected trait. Women, the choosier sex, are attracted to intelligence — expressed in anything from problem-solving to songwriting — because it’s a sign of “sexy” high-quality genes and overall developmental fitness. And because a woman can’t test a man’s sperm directly for these qualities, she has to judge him by what comes out of the head sitting on his shoulders.
