Ultrasound zap could work as male contraceptive

Experiments from the University of North Carolina suggests that zapping a male’s private parts with ultrasound could be one of the most effective and non-invasive forms of contraception.

According to the Daily Mail, the rsearch team found that rotating a three megahertz high frequency ultrasound beam around rats’ testes wiped out the germ cells that produce sperm. Best results were seen from two sessions lasting 15 minutes with the testes warmed to 37 degrees Celsius.
