title: Sexual dysfunction in patients with epilepsy.
abstract: Sexuality is an important and private aspect of life and sexuality and epilepsy have been intimately linked since ancient time. Disturbances of reproductive and sexual health are common in men and women with epilepsy. Multiple causes may lead to sexual dysfunction. The basis for hyposexuality has been attributed to both epilepsy and antiepileptic drug use, making it difficult to distinguish between the illness-specific and pharmacologic impacts on sexual functioning. Low levels of androgens are associated with sexual arousal insufficiency and sexual dysfunction. Data from animal studies support the hypothesis that hyposexuality occurs as a result of epileptiform activity in the temporal lobe, but not in the motor cortex. Enzyme-inducing antiepileptic drugs are metabolized in the hepatic P 450 system (e.g., 3A4, 2C9, 2C19), induce hepatic enzymes, increase the hepatic synthesis of sex hormone-binding globulin (SHBG), and increase the metabolism of sex hormones that might have an additional influence on sexuality in patients with epilepsy. When examining sexual dysfunction in men and women with epilepsy, the Arizona Sexual Experience Scale may be helpful in evaluating sexual function. Laboratory tests for estrogen, free and total testosterone, and serum SHBG may also be useful in evaluating sexual health.
