Premature ejaculation may be caused by kidney yang deficiency or kidney yin deficiency, as both can lead to premature ejaculation. If premature ejaculation is due to kidney yin deficiency, there may also be other symptoms such as nocturnal emission, tinnitus, dry mouth, and dry tongue, among others. If premature ejaculation is caused by kidney yang deficiency, it may also be accompanied by symptoms such as decreased sexual desire, reduced erectile function, poor erection, and weak lumbar muscles. Therefore, it is difficult to determine whether premature ejaculation is due to kidney yin deficiency or kidney yang deficiency. In such cases, it is necessary to visit the department of traditional Chinese medicine in a hospital, where a comprehensive dialectical analysis through pulse-taking and tongue observation can be conducted to identify the specific type of kidney deficiency, followed by targeted conditioning.
