   Scientists at the University of Missouri School of Medicine predict that "ultrasound" will soon be used as a birth control device for men.

   "Ultrasound" is a device that creates high frequency vibrations which, in turn, produce heat. The Missouri doctors have discovered that by applying low levels of heat to the testes of male rats for just a few moments, they have been able to make the rats completely sterile for three months or longer.

    The process involved is simple. The scientists merely heat the rats' testes from the normal temperatures of 34 degrees Centigrade to 39 degrees in a variety of ways. Among the methods used were hot water baths and "ultrasound devices."

    Doctor Mostafa Fahim says that the completely painless heat-raising procedures somehow interfere with the ability of the testes to produce sperm. Doctor Fahim predicts that, in the not-too-distant future, men will be purchasing small, comfortable ultrasound devices--that can be used pleasantly for five minutes or so. These devices, says the doctor, will make a man sterile for at least a few months after a single treatment.
