Ladies, you may catch a break soon from your contraception chores. A study has determined that sound waves reduce sperm counts to infertile levels in rats -- a technique that could also potentially work in humans.
The finding isn't without its detractors: Critics worry that the procedure may not kill all of a patient's sperm but merely damage it, while one doctor tweets an unsettling thought for pregnant women: "If ultrasound can make men infertile, I wonder what it does to a developing fetus."
The viability of this anti-virility procedure may ultimately depend on a more visceral reaction, one of which is expressed by this comment on Twitter: "You ain't going near my nuts."
Would you zap your or your partner's sperm as a means of birth control?
