In Traditional Chinese Medicine (TCM), the kidneys are considered the foundation of life, storing Essence (Jing) and governing growth, development, and reproduction. The Canon (《黃帝內經》) states that strong kidney energy is essential for fertility, as it nourishes the reproductive system and regulates hormonal balance. Kidney deficiency, whether in Yin or Yang, can lead to infertility, irregular menstruation, or low sperm quality. TCM treatments aim to strengthen kidney function, enhance blood circulation, and restore balance, improving fertility naturally. By addressing the root cause, TCM provides a holistic approach to reproductive health.
