COSO was born because the inventor, designer Rebecca Weiss himself, suffered from cervical cancer and was unable to take the hormonal contraceptive pill. Weiss noted that there are only two contraceptive methods for men: wearing a condom or vasectomy (pipe cut), and using ultrasound as a non-invasive , painless and side-effect-free contraceptive method. He states that he has adopted the law.
COSO was developed from ideas based on research published in 2012. In this study, when the testicles of rats were treated twice with 3MHz ultrasonic waves for 15 minutes while being soaked in saline while warming to 37 ° C, germ cells were almost zero. It is reported that the contraceptive effect was obtained for 2 to 6 months. Similarly, an experiment to 'apply ultrasonic waves to the testicles for contraceptive treatment' has been conducted since 1977, but experiments and research on humans have not progressed.
You can see how to use COSO by watching the following movie.

COSO looks like this.
Charge the COSO before use. The charging terminal is unique, and the cable can be fixed with magnetic adhesion.
When charging is complete, pour water inside the COSO.
Press the button on the back to heat the poured water.
When ready, the logo on the top edge and front of the COSO will illuminate.
Then insert the COSO into the testicles.
Ultrasonic heating is performed for a few minutes.
You can check the remaining time in real time from the dedicated smartphone app.
After some time, remove the testicles from COSO and finish. Previous experiments with rats have reported that azoospermia was maintained for several months to a year after ultrasound was applied to the testicles, but it is unclear how long it will take in humans. 'COSO is a reversible, hormone-free contraceptive method,' Weiss emphasizes.
The internal structure looks like this. The ultrasonic generator is built into the bottom.
The color version is planned to be white, black, and orange. The price is unknown at the time of writing the article.
At the time of writing the article, COSO has not yet been commercialized, and only a prototype has been created to show its technical feasibility. In order for COSO to be approved as a contraceptive device, it must go through clinical trials, which requires working with companies or research institutes to find sponsors, Weiss said.
