This device bathes the testicles and controls male fertility

In search of an alternative to the female birth control pill and the possible side effects of this method, the German designer Rebecca Weiss developed the prototype of a portable contraceptive for the exclusive use of men. The invention bears the name COSO and is in the running for the James Dyson International Design Award.

Designed for domestic use, the device is intended to guarantee men a kind of temporary and reversible infertility. In addition, the use of hormones is not required: the individual only has to give a “dip in the testicles”.

How does the device work?

To work, a person literally has to stick the testicles into the device, then fill it with water and let the liquid heat up. Finally, spermatogenesis – the production of sperm – is suppressed in men by the action of an ultrasound coupled to the device.

In other words, this male contraceptive generates ultrasound stimuli, temporarily suppressing the effects of the sperm. They lose mobility, which means they become less active and cannot fertilize the egg cell.

History of the invention of contraceptives for men

About a year ago I was diagnosed with cervical cancer because of contraception with the pill,” said the inventor of the device. “After that, hormonal contraception was no longer an option. When my partner and I looked for an alternative method, we found out about the lack of male contraception, ”he says.

“The problem is not unique. It affects many others [casais] Even. This can also be seen in today’s increasing public discussion about the lack of alternative contraception. That is why I decided to work on my master’s thesis in industrial design at the Technical University of Munich with the development of a new method of contraception for men, ”says Weiss, explaining the motivation that led her to develop the device.

After winning the German stage of the James Dyson Prize – and making it into the international finals – the inventor plans to test the functionality of the device, but still has to raise funds to finance the clinical studies.
