SPERM BRAIN LINK; HEALTH.

Byline: By MIRROR REPORTER

A MAN'S sperm quality turns out to be an indicator of his brain power, scientists claimed yesterday.

Researchers found men who scored highly in intelligence tests also had high counts of healthy sperm.

But low scores in intelligence tests showed men had fewer sperm and that they weren't so healthy.

Evolutionary psychologist Geoffrey Miller, who led studies at University of New Mexico, said: "It's not necessarily that the same genes are influencing sperm quality and intelligence.

"Rather, the two traits could be linked through a tangled web of biological and environmental interactions that has evolved to help women pick a mate."

"I'm thinking of intelligence as being related to individual fitness."
