A German design graduate by the name of Rebecca Weiss has invented a "Testicle Bath Contraception".

The invention, which is described as an "ultrasound-based, reversible and hormone-free male contraceptive device for home use" has been named "Coso" and has already bagged the Jame Dyson award, an international award that celebrates design and engineering, and will progress to the final stage of the competition. 

Putting a responsible twist on the term 'teabagging', the device is used by filling it up with water, heating it to the required temperature and placing one's testicles inside the device. 

Following this, the testicles are hit with ultrasound for several minutes and this suppresses spermatogenesis, leaving the user temporarily infertile. 

This nifty device allows the user comfort and convenience by 'teabagging' the chargeable device in the comfort of their own home, without the stress of impregnating their partner or the rush of obtaining a Plan B pill.

'The problem is not unique to me'

Weiss told the Dyson Awards that she thought of the idea after becoming aware of the overwhelming lack of male contraceptives and a negative experience with contraception herself. 

After using 'the pill', Weiss was diagnosed with cancer precursor cervix, and hormonal contraception was ruled out as an option. 

"The problem is not unique to me personally. It affects many others as well," says Weiss. "This is also evident in the current growing public discussion about the lack of contraceptive alternatives. So I decided to deal with the development of a new contraceptive approach for men in my master thesis in Industrial Design at the Technical University in Munich." 

Though using ultrasound as a form of contraception has previously been tested on animals and was found to significantly suppress spermatogenesis, Weiss hopes to raise funds and progress her invention to clinical trials.
