Clogged arteries in older men are commonly associated with low or low-normal testosterone levels. This narrowing of the arteries is usually due to the buildup of plaque within the cardiovascular system. Inside the artery walls, your cardiovascular system is responsible for carrying blood and essential nutrients to your body. In order to get an erection, the male body requires a strong and steady blood flow to the penis and other extremities.
However, this is harder than you may think, especially for men over the age of 40. You see, at this point in life, it is common for the Standard American Diet (SAD) to take a toll on the cardiovascular system. In fact, this diet that includes red meats, refined carbohydrate products, dairy and even fast food has been linked to the depleted health status of Americans.
Men who do not produce enough male sex hormone (testosterone) suffer from what is known as hypogonadism. This health problem can negatively affect the sex drive and energy levels of men. However, one study showed that for men with hypogonadism, a 2% testosterone solution was an effective therapy for the symptoms. This leads us to conclude that testosterone replacement therapy positively affects libido.
