Topic Overview

Hormonal factors may play a role in erection problems (erectile dysfunction). Men who produce low levels of the hormone testosterone (a condition known as hypogonadism) may have decreased sexual desire. A blood test is usually done if your doctor suspects this problem. But few men with erection problems have low testosterone production.

Producing high levels of the hormone prolactin (hyperprolactemia) also may be a factor. High levels of prolactin interfere with testosterone production, resulting in a form of hypogonadism.

Medicines are available to treat low testosterone production and excess prolactin production.
