Research showed that men of erectile dysfunction drugs are 3 times more prone to STDs than those who are not taking Viagra, Cialis, or Levitra.

A recent study carried out by medical experts of Harvard University showed that men suffering from erectile dysfunction and taking prescribed ED medication (such as Viagra and Cialis) are 3 times more prone to having STD (sexually transmitted disease) than others.

The study published in Annals of Internal Medicine was based on the analysis of insurance claims made by men in their 40’s.

The results suggest, however, that it is the nature of men rather than erectile dysfunction drugs that lead to increased risk of sexually transmitted diseases.

The higher rate of STDs was seen in the year preceding and following the one that men started to take Viagra, Cialis or Levitra.

The risk of STD is 2.8 times higher in the first year that men are on ED drugs, and 2.65 in the second year.

This fact led Harvard researchers to a conclusion that patients on ED medication are more prone to have unsafe sex.

Researchers also found out that despite the fact that young men have more sexual partners than men in their 40’s, the latter have higher rate of STD because they prefer unsafe sex.

As such, the overall proportion of middle-aged men diagnosed by HIV/AIDS reaches 44%.

The authors of the research were unable to determine whether it was the sexual behavior of men on ED medication that led to higher STD rate.
