Male Sexual Dysfunction

男性性問題在男性性功能障礙

Sexual dysfunction is any physical or psychological problem that prevents you or your partner from getting sexual satisfaction. Male sexual dysfunction is a common health problem affecting men of all ages, but is more common with increasing age.

Sexual disorders in men are categorized according to their occurrence in the cycle of sexual response into disorders of desire, arousal (erectile dysfunction), or orgasm (premature or delayed ejaculation, or anorgasmia), albeit with considerable potential for overlap and concurrence between these disorder groups. It is essential to understand the different types of sexual disturbance in their biopsychosocial context as well as the significance of sexuality for the individual, and for the couple, with respect to reproduction, sexual pleasure, and bonding. Sexual disturbances are common.

Laumann et al. (1999) found in a representative cross sectional study of 18 to 59 year old US citizens a 5% prevalence of desire or erectile dysfunction and a 21% prevalence of premature ejaculation. International comparison (Laumann, et al. 2005) revealed some similarities, but also significant intercultural variations corroborating the biopsychosocial etiology of these disorders. A number of studies have also confirmed the negative effects of functional sexual disorders on relationships and quality of life.
