Are premature ejaculation and lower back pain signs of kidney yin deficiency?

TCM believes that kidney yin deficiency may lead to insufficient kidney essence, resulting in failure to secure the seminal gate and possibly causing premature ejaculation. Meanwhile, insufficient kidney yin fails to nourish the meridians of the lower back, leading to soreness in the waist. If these manifestations are accompanied by typical symptoms of yin deficiency such as tidal fever, night sweats, dry mouth and throat, heat in the palms and soles, dizziness, and tinnitus, the condition is most likely related to kidney yin deficiency. Treatment should primarily focus on nourishing yin and tonifying the kidneys.
