The Male Contraceptive Involves Men Injecting Their Balls

Yeah...that'll happen.

A male-specific contraceptive could finally be on its way, but there's probably more chance of you persuading your man to just stop having sex than to volunteer for this. Why? Well, it involves getting an injection. In their balls.

The RISUG (Reversible Inhibition of Sperm Under Guidance) was invented back in the '70s, but has now been developed by the Parsemus Foundation to create a male birth control called Valsalgel. The big sell is that it is thought it could last as long as ten years.

The treatment involves a doctor injecting a synthetic gel into the vas deferens—the tube that transports sperm out of the testicles. The man would still ejaculate, but the gel filters the sperm out of the semen.

The main benefit is that unlike a vasectomy, the whole procedure is completely reversible. All the patient needs to do is have a sodium bicarbonate solution injected into the same spot, which dissolves the gel.

Aaron Hamlin, executive of the Male Contraceptive Initiative, told Vice: "There's nothing for you as a person to screw up. When you have a method that doesn't require you to do anything, like Vasalgel, you get the injection into the vas deferens and walk out the door. After all that's done, when it's time for you to have sex, everything you've had to do is already done."

While a male pill would require a partner to trust that their man had remembered to take it, this would erase that issue (unless the man in question had some secret desire to leave a trail of illegitimate children across the world and so lied and said he'd had the injection when he hadn't… but seems unlikely.) The only issue would be that this would of course still not protect against STIs.

The company explain on their website: "12 months of rabbit studies have shown no sperm from the second semen sample onwards! Sperm flow quickly returned in rabbits that had the polymer flushed out.

"Human trials are expected to start in 2016 and 2017. If everything goes well and with enough public support, we hope to get Vasalgel on the market as early as 2018."
