Does masturbation lead to kidney yin deficiency or kidney yang deficiency?

Masturbation may lead to kidney yin deficiency, kidney yang deficiency, or both. According to TCM theory, excessive masturbation may affect the balance of kidney yin and yang. Kidney yin deficiency is mainly caused by frequent sexual stimulation and excessive semen depletion during excessive masturbation, which may lead to kidney yin deficiency. Kidney-yin has the functions of moistening and quietness, etc. Deficiency of kidney-yin may cause a series of manifestations of yin deficiency and internal heat, such as soreness of waist and knees, dizziness, tinnitus, hot flashes, night sweats, five-upset fever, dry mouth and pharynx, etc. The occurrence of kidney-yang deficiency may be due to excessive masturbation damaging kidney-yang. Kidney-yang is the root of yang qi. When kidney-yang deficiency occurs, it will show cold pain in the waist and knees, cold limbs, decreased libido, impotence, premature ejaculation, listlessness, edema of the lower body and other deficiency cold symptoms. In addition, long-term excessive masturbation may also damage both yin and yang of the kidney, both yin deficiency symptoms and yang deficiency manifestations. At the same time, it should also be noted that the occurrence of kidney yin deficiency and kidney yang deficiency does not only depend on masturbation, but also on individual constitution, living habits, mental state, etc.
