PSA testing got a major lift from an endorsement by the American Cancer Society which has a history of overselling the value of early detection and advising the public to seek tests before their safety and efficacy has been established. Medical organizations like the American College of Physicians and the U.S. Preventive Services Task Force that carefully search the scientific evidence before making screening recommendations have refused to endorse the PSA test.

This process results in relaxation of the muscle in the blood vessel walls that keeps blood from flowing into the penis. Lots of different things can go wrong along the way, which is why there are so many different causes of ED. The finding comes on the heels of work conducted at Fox Chase last year.
