When it comes to Vacuum Erection Pumps, there's no shortage of jokes, myths and credulous advice. Here are the facts: Penis Pumps work by using a vacuum seal to push the flow of blood into the penis, making erect. It's just that simple.
This makes pumping one of the best treatment options for erectile dysfunction available. For men without ED, pumps can also be useful for creating thicker, harder erections during sex or masturbation. As for those "huge permanent size gains" you might have read about, there isn’t much evidence of them permanently increasing penis size. Sorry!
That said, studies have shown if you go long enough without a spontaneous erection, some of your penile tissue can atrophy and cause long-term dysfunction. It turns out that use of a Erection Pump may prevent this damage from happening - which sounds like a great reason to use one.
