Men's Sexual Problems Due To Low Testosterone Or Something Else?

Even though "low testosterone and sexual problems quite often coexist," according to hormone expert Dr. Frederick Wu, a new study shows that decreasing levels of testosterone does not necessarily cause impotence or decreased libido.

Dr. Wu told Reuters Health that "most people with erectile problems do not have hormone problems...but often have blockages in the arteries to the penis."

Testosterone levels dwindle with age, race, country. But in men who admit to some sexual dysfunction, age, urinary symptoms, body mass index and diabetes impacted performance more!
