Impotence (Erectile Dysfunction)

Erectile dysfunction, also known as impotence, refers to the inability to achieve or maintain an erection sufficient for sexual intercourse. It can be categorized into two main types. First, primary erectile dysfunction refers to cases where an individual has never been able to engage in sexual intercourse since birth. Second, secondary erectile dysfunction describes situations where a person who was previously able to engage in sexual intercourse becomes unable to do so due to specific circumstances.Additionally, erectile capacity may be normal, but psychological factors may prevent adequate erection, which is termed functional erectile dysfunction. Conversely, organic erectile dysfunction occurs when sexual intercourse is not possible due to abnormalities in the nerves, blood vessels, hormones, or physical deformities of the penis (e.g., penile amputation). There is also mixed erectile dysfunction, which involves a combination of functional and organic factors, as well as transient erectile dysfunction caused by certain medications (e.g., antipsychotics, anxiolytics). Generally, secondary erectile dysfunction and functional erectile dysfunction are the most common.In cases of severe penile injury or significant spinal cord damage affecting the erectile center, recovery may not be expected solely through medication. When the cause of sexual dysfunction involves issues on the female side, it is conventionally referred to simply as "impotence," rather than erectile dysfunction. Causes on the female side may include vaginal agenesis, hymenal hypertrophy, vaginismus, and sexual aversion disorder. The sexual dysfunctions seen most frequently—secondary and functional erectile dysfunction in men, and vaginismus and sexual aversion disorder in women—are often well-suited for treatment in traditional Korean medicine (Han medicine).In traditional Korean medicine, the kidney (신, "shin") is considered the foundation for sexual and reproductive functions, thought to be deeply related to them. Thus, when kidney function weakens, impotence may occur. In Chinese medicine, erectile dysfunction is often viewed as arising from a deficiency in kidney yang (신양, "shinyang"), reinforcing the close relationship between sexual function and kidney health.Emotional factors are also significant contributors to erectile dysfunction. Feelings of frustration, worry, excessive thinking, and anger can damage the liver, leading to dysfunction in the central and autonomic nervous systems and ultimately resulting in erectile dysfunction. Moreover, prolonged stress can lead to overexertion of the nerves, damaging the heart and spleen, which reduces the generation of vital energy (기혈) and can further contribute to sexual impotence. Chronic debilitating diseases that deplete vital energy also make it understandable that one may develop erectile dysfunction.Dietary habits play an important role as well; excessive consumption of strong alcohol and rich foods over long periods can impair the spleen, leading to the accumulation of dampness and heat in the body. This condition can hinder the circulation of vital energy in the lower abdomen, making it difficult for the penis to achieve an erection.
