When it comes to how to improve sperm count, remember that if sperm were deeper inside the body, and therefore at body temperature, they would be overactive and burn themselves out. Humans have external testicles to keep sperm cooler and dormant. When they enter another body, they reach the temperature needed to get active. To help, guys should wear loose, thin underpants (20 January, p 40).
