We're Back: 100% More Boners

A new study, conducted on hamsters has discovered the one of the active ingredients in Viagra is helpful in stopping the problems that come about when travelling. Namely, jetlag. And this is just great, now we will have instead of thousands of weary travellers, we will have thousands of perky travellers all rocking massive Viagra-enhanced erections. Yikes.

Sildenafil, the active ingredient in Viagra, is known to inhibit the degradation of cyclic guanosine monophosphate (cGMP), a messenger molecule that advances the body clock in response to light. So researchers assumed, Golombek says, that higher levels would increase the sensitivity of the circadian system and, in the process, "accelerate adaptation to a changing light schedule."

Their results, published in the current issue of Proceedings of the National Academy of Sciences USA: Hamsters given sildenafil (in concentrations of 3.5 parts per million in solution) adjusted to a six-hour change in their light-dark cycle (the equivalent of the time-change experienced by passengers traveling between New York City and Paris) in eight days; it took hamsters injected with saline solution 12 days to recover, as measured by what time they began their daily jog on running wheels in their cages. A larger dose of sildenafil sliced the adjustment time in half to six days, but also brought on penile erections, as the drug was approved to do.

I love you Science.
