First, the kidneys govern endurance. In traditional Chinese medicine, the kidneys are believed to store essence, and kidney qi has a consolidating and controlling function. If the kidneys are deficient, the kidney meridian may easily lose control, leading to issues such as premature ejaculation. Along with kidney deficiency and instability, symptoms like soreness and weakness in the lower back and knees, tinnitus, and fatigue may also occur. In such cases, the focus should be on tonifying the kidneys.

Second, the liver governs firmness. Traditional Chinese medicine holds that the liver governs tendons and stores blood, while the kidneys store essence. Since essence and blood share the same source, the liver and kidneys are closely related. For the genitals to be firm and resilient, an ample supply of essence and blood is essential. If the liver is impaired, qi movement can stagnate, potentially disrupting the supply of essence and blood. As a result, the genitals may become as soft and limp as a deflated balloon. Individuals with liver stagnation may also experience symptoms such as irritability, a quick temper, and frequent sighing. In such cases, the approach should focus on soothing the liver and regulating qi.

Third, the spleen governs physical strength. Traditional Chinese medicine believes that the spleen is the source of qi and blood production, transforming food into qi and blood to supply all parts of the body and nourish the whole. Therefore, when the function of the spleen and stomach is strong, a person's physical strength will be abundant and vigorous. When the spleen and stomach are deficient, qi and blood are also prone to deficiency, leading to a feeling of fatigue in everything, a lack of energy and reluctance to speak, and a disinterest in moving or talking. Over time, bodily functions may decline, making everything even more difficult. In such cases, the focus should be on regulating the spleen and stomach.
