Erectile dysfunction or impotence is the men’s inability to acquire or uphold a hard erection during lovemaking. Male impotence not tricky for just him, but his woman can have a very challenging time coping with his trouble as well. Feeling unsatisfied, annoyed, sad, confused, insulted and even unattractive are all common negative emotions that a woman may experience if her man is facing erectile difficulties. Although handling their partner’s erectile difficulties is problematic for women, some things can be done to make it easier. ED Pills work by inhibiting an enzyme called phosphodiesterase type-5 (PDE5). Blocking this enzyme causes the blood vessels in the penis responsible for achieving and maintaining an erection to dilate. However, no erection will occur without an environmental or psychological trigger to stimulate sexual arousal. Very effective. Studies have shown that 60 to 70 percent of men with ED see positive results.
