The three most common male sexual dysfunctions are decreased libido, erectile dysfunction (ED), and ejaculatory dysfunction (including premature ejaculation [PE] in men ages 18 to 59 years). One or more conditions can co-exist in an individual. The inability to achieve and maintain an erection sufficient for satisfactory sexual intercourse is a distressing and common symptom, affecting up to one-third of adult men. ED is common in men with systemic disorders such as hypertension, ischemic heart disease, and diabetes mellitus, and its prevalence increases with age. Integration of Chinese medicine and western medicine would be a good choice for this disease. When treating male sexual dysfunction, Chinese doctors will take everything into consideration, including the following conditons.

1. Physical causes: Many physical and/or medical conditions can cause problems with sexual function. These conditions include diabetes, heart and vascular (blood vessel) disease, neurological disorders, hormonal imbalances, chronic diseases such as kidney or liver failure, and alcoholism and drug abuse. In addition, the side effects of certain medications, including some antidepressant drugs, can affect sexual desire and function.

2. Psychological causes: These include work-related stress and anxiety, concern about sexual performance, marital or relationship problems, depression, feelings of guilt, and the effects of a past sexual trauma.
