A new innovative “testicle bath” could be the future of male contraception. The small ultrasound-based device is a reversible and hormone-free method that “temporarily changes spermatogenesis”.
After the device has been set up by a doctor, the user fills the device with water and is “heated up to operating temperature”. They then bathe their testicles in the capsule for a gentle ultrasound treatment that stops sperm production and allows contraception from around two weeks after the first application.
COSO explains: “Ultrasound generates deep heat in the testicular tissue which, when applied twice, changes the mobility of the sperm and temporarily inhibits the formation of new sperm.
“As a result, the female egg cannot be fertilized. It leads to reliable contraceptive effectiveness. “

The groundbreaking device won the prestigious James Dyson Award, which declares that the device can be monitored in real time via the COSO app. When the treatment is complete, the device switches off automatically.
“After the treatment, the device switches off automatically.”
The designer Rebecca Weiss talks about the inspiration behind the design called: “About a year ago I was diagnosed with cancer of the cervix due to contraception with the pill.
“After that there was no more hormonal contraception. When my partner and I looked for an alternative method, we became aware of the lack of male contraception.
“The problem is not unique to me personally. It affects many others as well. This can also be seen in the currently increasing public discussion about the lack of alternative contraception.
“That’s why I decided to work on the development of a new method of contraception for men in my master’s thesis in industrial design at the Technical University of Munich.”
The device is still a “hypothesis” and although the ultrasound method has been successful in animal mode, it is not yet transferable to humans as more money is needed for further studies and clinical trials.
