Rebecca Weiss had some problems in her own sex life before she developed a contraceptive for men. Realizing that the birth control pills she used for protection were damaging her body, the scientist wanted to focus on this subject as her master’s thesis when she realized that there was no method by which her boyfriend could be protected.
After pondering this research for a long time, Weiss came up with an ultrasound-based device called a testicular bath. The working logic of this device, which was awarded the Dyson Award, is quite strange.
The purpose of testicular bath is to reduce sperm motility.
Weiss, the inventor of the testicular bath, explains why he needed such a device with the following words; “While my partner and I were looking for alternative methods, we realized how limited male birth control was, so I decided to develop it. Then hormone drugs were no longer an option for me. While looking for alternative methods with my partner, we realized how limited male birth control is. In my master’s thesis at the Technical University of Munich, I decided to develop a new approach to male contraception.”
The testicle bath, which looks like a bowl, is used just before sexual intercourse. The device is first adjusted according to the testicular size of the male partner, and then a certain amount of water is placed in the bowl. Later, the male partner places his testicles in this bowl, and ultrasound waves are activated, stopping sperm motility until they are no longer able to fertilize the eggs.
