THE scientific research of 2012. New contraceptive device for men. Do you want to have sex but no offspring? Oops, let's wait 15min so I can zapp my testicles with ultrasound. (At least the monkeys didn't mind. There is a possibility that it feels right, it only sounds weird)
"Researchers at the University of North Carolina School of Medicine rotated high-frequency ultrasound transducers around the testes of rats. They put the animals’ testes in a cup full of saline solution to provide better conduction between the transducer and the skin. Then they measured the animals’ sperm counts to see how much they dropped. After several tests, scientists led by James Tsuruta found the ideal therapy was two 15-minute sessions, two days apart, which led to a dramatic reduction in sperm."
