Optimal male sexual health includes sexual desire (libido) and the ability to get and sustain an erection (erectile function). Although physiology can affect both the desire for sex and the ability to have sex, mental health and emotional factors also play important roles.
Male sexual health isn't merely the absence of disease. Erectile dysfunction (ED) is the inability to get an erection or to maintain it long enough for satisfying sexual activity. Many things can cause ED, including stress, depression, relationship issues, abnormally low testosterone, damage from urological surgery, and even cholesterol-clogged arteries. In fact, it is often an early warning sign for heart disease. ED can be treated with pills, injections into the penis, or devices. Men can also experience difficulties related to ejaculation, including premature ejaculation, delayed ejaculation, or the inability to experience orgasm upon ejaculation (anorgasmia).
One of the best ways to improve your health is cardiovascular exercise. Sex might get your heart rate up, but regular exercise can help your sexual performance by keeping your heart in shape.
