Scientists are developing a new method of contraception for men that could prove to be much more reliable than previous methods, such as the use of condoms or vasectomy. The new method of contraception is based on the use of ultrasound. Researchers believe that exposing the testicles to ultrasound can reduce sperm production by 10 times, leading to effective contraception. Ultrasound results in the generation of heat in physically vibrating tissues. Prolonged exposure to ultrasound can change tissue structures and stop sperm production. This is a temporary process, the research team explains. As time passes and the sound waves cease, sperm production returns to normal, they add. However, further studies in this direction are needed to confirm the thesis of the research team. The study has not yet been conducted on humans. This is not the first case of using the ultrasound technique for medical purposes, explains the research team.
