The Indian Council of Medical Research (ICMR) has 'successfully completed' a seven-year follow-up study for injectable, reversible, safe, effective, and long-lasting male contraception.
The Reversible Inhibition of Sperm Under Guidance – RISUG – as the contraception is being called, has shown an efficacy of 99.02 percent in the prevention of pregnancies, showed the results in the follow up study which has been published in the open access journal of Andrology.
The big point: RISUG is a non-hormonal injection that can have long-lasting effects.
The overall efficacy of the drug is 97.3 percent to induce azoospermia - when there is no sperm in the ejaculate. And has a 99.02 percent efficacy in the prevention of pregnancies (which is higher than that of condoms).
