缩阳
Traditional Chinese Medicine Definition
Shrinkage of the Penis, a term in traditional Chinese medicine (TCM) that falls under the category of urological diseases. According to the "Textbook of Internal Medicine in TCM," shrinkage of the penis refers to a condition where the penis fails to maintain a firm erection or quickly becomes flaccid after an erection, accompanied by symptoms such as a tight and cold pain in the lower abdomen, weakness in the lower back and knees. This syndrome is often attributed to deficiencies in the liver and kidney, invasion by cold pathogenic factors, or blood stasis.
Shrinkage of the penis is a common urological disease in clinical practice of TCM, with its core pathogenesis mostly related to deficiencies in the liver and kidney, and invasion by cold pathogenic factors. Common precipitating factors include prolonged illness leading to physical weakness, emotional disorders, and overexertion. During the differentiation of symptoms, attention should be paid to distinguishing between cold and heat, deficiency and excess, such as the syndrome of cold retention in the liver meridian, which manifests as the penis retracting, a tight and cold pain in the lower abdomen, aversion to cold, etc. During treatment, it is necessary to warm the liver and dispel cold, and invigorate the channels and collaterals. For the syndrome of kidney yang deficiency, it manifests as recurrent episodes, aversion to cold, cold limbs, weakness in the lower back and knees, etc., and treatment should focus on warming the kidney and replenishing yang, and dispelling cold to activate the channels. In clinical practice of TCM, the overall direction of treatment for shrinkage of the penis suggests harmonizing yin and yang, and smoothing the meridians and collaterals to restore the normal erectile function of the penis.
