Testicular zap 'may stop sperm'
A dose of ultrasound to the testicles can stop the production of sperm, according to researchers investigating a new form of contraception. ...The concept was first proposed in the 1970s, but is now being pursued by researchers at the University of North Carolina who won a grant from the Bill & Melinda Gates Foundation.
A new contraceptive for men on the horizon? Just a couple of zaps of ultrasound kills sperm, say scientists
The Daily Mail (United Kingdom)
...Study leader Dr James Tsuruta, from the University of North Carolina, said: 'Unlike humans, rats remain fertile even with extremely low sperm counts. 'However, our non-invasive ultrasound treatment reduced sperm reserves in rats far below levels normally seen in fertile men. 'Further studies are required to determine how long the contraceptive effect lasts and if it is safe to use multiple times.'

Cancer treatment method allows for more targeted approach
Treating cancer is always tricky, but some cancers occur in parts of the body where radiation treatments may have harmful side-effects on surrounding organs or healthy structures. It makes the treatment approach more difficult, but not impossible. Thanks to a new technology called tomotherapy, treating hard-to-get-to types of cancer has become a bit less complex. ...Rex and the University of North Carolina at Chapel Hill Medical Center are two of the three hospitals in the state that have tomotherapy units.

...James Tsuruta, an assistant professor of pediatrics at University of North Carolina School of Medicine, and his colleagues report in the journal Reproductive Biology and Endocrinology that commonly used doses of ultrasound can lower rats’ sperm concentrations to 3 million per milliliter of semen; experts define low sperm counts in men as anything less than 20 million sperm per milliliter of semen.
