"Testicle Bath" Birth Control Device Wins Prize. Bonus Instructional Video!

Via upi.com. Rebecca Weiss, an industrial design graduate from the University of Munich and inventor of the COSO male birth control device, had a ball this weekend after she was named Germany's winner of the James Dyson Award which, "celebrates, encourages and inspires the designers of new problem-solving ideas."

The COSO uses an ultrasound "testicle bath" to temporarily stop sperm mobility. And you only have to use it every few months to keep your boys from swimming. Weiss said that when she and her partner were looking for an alternative method of birth control, they became aware of the lack of male contraceptives, and she got to work. But, how does it work you ask?

Check out this handy instructional video on how to use the "Testicle Bath."
