Would men endure a shot in the penis to prevent pregnancy? Indian researchers think so. The Indian Council of Medical Research, a government-funded biomedical research agency, has successfully completed a clinical trial on an injectable male contraceptive.
The product is ready, with only regulatory approvals pending [from the government], Dr. R.S. Sharma, senior scientist with ICMR, told the local news outlet. The trials are over, including extended, Phase 3 clinical trials for which 303 candidates were recruited with a 97.3% success rate and no reported side effects. The product can safely be called the worlds first male contraceptive.
The birth control method, which lasts approximately 13 years, involves injecting a polymer, called styrene maleic anhydride, into the vas deferens, effectively blocking sperm from leaving the testicles. The shot, preceded by a dose of local anesthesia, is designed to supplant a traditional vasectomy.
Researchers in the US have developed a similar contraceptive, called Vasalgel, which has not yet been brought to market. A male birth control pill also exists, though researchers anticipate itll be about 10 years before the drug makes it to market.
