Scientists at the University of North Carolina start clinical trials of an innovative male contraceptive that is expected to be less expensive, non-hormonal and reliable. The new method uses a blast of ultrasound to the testicles, which prevents sperm production for six months. This male birth control option is claimed to be reversible and suitable to many couples. When a man's testes will not produce sperm and the sperm reserves will be deleted, the man becomes temporarily infertile, but fertility returns in six months.
Experts hope that the new male birth control method will soon become available to many men worldwide. The clinical trials are aimed at testing the effectiveness of this method and ensuring its safety.
