A team of researchers at UC Berkeley has decoded the “force,” which imparts a sperm the ability to swim and drill through a female egg to achieve its Darwinian destiny. The scientists claim they can now turn off this “power switch,” in sperms, thus offering a better contraceptive than the traditional ones that keep sperm from fertilizing eggs by barrier action.

Study leader and biophysicist Polina Lishko says the new method is 10 times more potent in preventing fertilization than any other option currently available in the market, writes Wired.

The study, published in PNAS, is more exciting as it shows the prospect of first effective male contraceptive since the introduction of the condom.
