Male Contraception With an Ultrasound Device?

A fascinating new device could one provide the elusive male contraceptive:

German design graduate Rebecca Weiss has won a James Dyson Award for a male contraceptive device called Coso, which uses ultrasound waves to temporarily halt sperm regeneration.

Weiss’s Coso device is designed to be a reversible contraceptive solution. To use it, a person would fill the device with water up to the indicated mark, turn it on so it heats to operating temperature, and sit for a few minutes with their testicles dipped into it.

Coso looks like it could be the newest Alexa. It even comes with an app to show where you are in the process.

Right now, this device is just a prototype and is not available to the public. Its technology is based on a published study in the journal Reproductive Biology and Endocrinology.

This study successfully used ultrasound currents on rat testes in order to reduce sperm count. It will take a lot more research to determine this is safe and effective in humans.

If it works, I think this innovation could be transformative. Most, if not all, of the burden of contraception is generally on women. Those methods often have significant side effects.

Perhaps there is a better way!

I think a startup like this would make a wonderful candidate for Y Combinator, which backs startups from all over the world in areas including biotech and medical devices.

Best of luck to the amazing Rebecca Weiss!
