According to Pfizer, the manufacturer of Viagra, they indicate the drug is clinically proven to improve erectile function in most men with E.D.

A 28-week study was done by Pfizer of more than 500 men with E.D. where roughly 102 men took 100 mg of Viagra and 205 men took sugar pills and the remaining patients took other doses of VIAGRA. Results of the study found that 85% of men with E.D. who took 100 mg of Viagra achieved fairly strong erections versus 50% of men who were given sugar pills.

Pfizer also indicates that women too have been satisfied with the drug, showing in their study that 92% of women said “Viagra improved their partners’ erections” versus 19% of women whose partners were given sugar pills.
