The main strength of Risug? Not to be a remedy of permanent type: the contraceptive efficacy of the injection, in fact, lasts about 13 years. It is, therefore, of a technical, reversible and less invasive (injection is carried out after administered local anesthetic) compared to the vasectomy, surgery permanent, provides for the interruption of the ducts and the vas deferens of the male and that is still today considered to be the contraceptive method male safer in terms of effectiveness. The trial in India Currently, the Indian Council of Medical Research (ICMR) has successfully completed clinical trials and is awaiting a response from the Drug Controller General of India (DCGI) for the final approval. In particular, for the last step of the trial, stage three, were recruited 303 male participants and none of them have reported any significant side effects following the injection. The results obtained are encouraging, considering also that the treatment has proven effective in 97.3% of cases.
The polymer used in the method Risug, however, is not a new discovery. Since it was designed by the Indian Institute of Technology, in the ’70s, researchers are trying to make it a product suited to a large-scale marketing and, therefore, suitable to the indian market, where 53.5% of couples used contraceptive methods, mostly of the permanent type. The figure, on the surface, it may seem quite unusual, especially considering that only 0.3% of men undergo sterilization (vasectomy) against 36% of women, but in reality it hides a social problem linked to the population control policies.

Despite depends very much from the culture of the country, apparently, there are few men that would love to experience a contraceptive the male as the Risug. For example, a survey this year showed that a third of british men would like to use a contraceptive male of long duration, and the percentage goes up to 40% in men between 25 and 49 years old. The test in the United States, in Parallel, in the United States, the other treatment based on the methodology Risug is still in the animal testing, but the results obtained seem to be promising. This is the Vasalgel, a hydrogel with a formulation slightly different than the product the indian, but whose working principle is always based on the inhibition of the movement of the sperm through a mechanical barrier formed from a polymer injected into the site. An injection of sodium bicarbonate, then, always at the level of the ducts and the vas deferens, seems to be sufficient to dissolve the structure of polymeric gel, thus freeing the channels blocked by the barrier formed by the polymer, and returning the fertility. With regard to the effectiveness of a contraceptive in terms of the duration, or prediction as to the timing of the distribution of the product, however, still know little.
