Ultrasound Halts Sperm Production

Zapping testicles with ultrasound appears to reduce sperm counts to low levels in rats.

WIKIMEDIA COMMONS

Researchers at the University of North Carolina at Chapel Hill are working on a project they hope will provide a simpler method for male contraception.  By exposing rat testicles to two 15-minute doses of ultrasound, they found that sperm counts dropped to levels that are usually associated with infertility in humans.

The research was performed with the help of a grant from The Bill and Melinda Gates Foundation, but is still far from ready for prime time. It’s still unclear, for example, if the effects are reversible, and whether there might be long-term damage from repeated doses. In addition, sperm must be killed completely rather than simply damaged, since damaged sperm could produce a child with birth defects.

"The last thing we want,” Allan Pacey, from the University of Sheffield told BBC News, “is a lingering damage to sperm."

What kind of referees approve a GRANT like that? Why don't they cook the testicles in a microwave oven to see if they can stop sperm production. I get a better idea to stop ovarian cancer but it may be offensive, as much as zapping your testicles with radiation. I wonder what they will come out to cure head ache.
