Premature ejaculation may be due to kidney yin deficiency, kidney yang deficiency, or both kidney yin and yang deficiencies, or other organ deficiencies. It should be judged based on accompanying symptoms. If premature ejaculation is accompanied by symptoms such as dry mouth, dry tongue, night sweats, nocturnal emission, dizziness, and tinnitus, it may be due to kidney yin deficiency; while if premature ejaculation is accompanied by symptoms such as coldness in the lower back and knees, fear of cold, and fatigue, it may be due to kidney yang deficiency.
