Ultrasound could be used as a male contraceptive
London: University of North Carolina experts believe a blast of ultrasound to the testes can safely stop sperm production for six months.
The boffins, in fact, are beginning to conduct tests to see if ultrasound can be used as a reversible male contraceptive, reports The BBC.
Lead researcher Dr James Tsuruta said: "We think this could provide men with up to six months of reliable, low-cost, non-hormonal contraception from a single round of treatment.
"Our long-term goal is to use ultrasound from therapeutic instruments that are commonly found in sports medicine or physical therapy clinics as an inexpensive, long-term, reversible male contraceptive suitable for use in developing to first world countries."
According to the boffins, once the testis has stopped producing sperm and all "sperm reserves" have been depleted, the man will be temporarily infertile.
