The Future of Male Contraception?

From the explanation on the Dyson Awards website:

COSO is an ultrasound-based, reversible and hormone-free male contraceptive device for home use…

The user puts water into the device up to the indicated mark… the water is heated up to operating temperature. The user spreads his legs and sits down to place the testicles in the device. The ultrasound process continues for a few minutes. The remaining time can be monitored in real time via the COSO app.

So far, the procedure has been applied to animals. Therefore, the technical parameters are hypothetically transferred to humans.
