Sexual dysfunction is a quality-of-life issue for men and women. Men may have libido (sex drive), ejaculatory or erectile difficulties. Some form of sexual dysfunction affects half of all men over age fifty. Women may suffer from difficulties with libido, sexual arousal, orgasmic function or vaginal lubrication. A recent survey in The Journal of the American Medical Association (JAMA) stated that more than 40 percent of women may be affected by these types of sexual dysfunctions. In addition, testosterone deficiency may be present in both men and women.
