Attention, swordsmen of the world. A decade of childless shenanigans awaits you.

It’s called RISUG (reversible inhibition of sperm under guidance) and it’s recently been shown to be 100% effective for a minimum of 10 years with no side-effects and complete reversibility.

The thing that makes RISUG so effective is that it is not a drug, it’s a polymer – a positively-charged polymer to be precise. Sperm, you see, are negatively charged – so when they travel past the polymer as they pass through the vas deferens – they get zapped. Obviously the catch is that the polymer must be injected into the vas deferens via the scrotum – but the 15-minute procedure is probably a lot less painful than it sounds… and much less painful than childbirth.
