Researchers reviewed 14 studies that monitored the effects phosphodiesterase type 5 inhibitors—drugs for erectile dysfunction like Viagra and Levitra—had on men who experience premature ejaculation (PE). Eleven of the studies showed medication helped extend the length of the time they could go before reaching orgasm.
So does this mean that science has found the magic pill for helping you go all night? Not exactly.
The researchers stress that although this correlation was found, it’s hard to determine whether or not the ED medication was actually responsible for the delay in orgasm since a majority of the studies did not compare the results against a placebo.
