In Traditional Chinese Medicine (TCM), although males become sexually mature at 16 years old and females start menstruating at 14, marriage should not occur until their late twenties or early thirties. This is because for girls who have not yet reached adulthood, if they engage in sexual activity too early, it can lead to premature loss of yin energy, causing damage before full development. This may result in infertility, miscarriage, or giving birth to weak children. Therefore, it shows how difficult it is for yin energy to fully develop and why it needs to be preserved.
The process of having sex requires hormonal regulation and excitation of the cerebral cortex, which are extremely physically demanding. Thus, TCM believes that excessive consumption of fundamental substances leads to a situation where the body cannot naturally regulate and replenish itself. When output exceeds input, it results in deficiency.
In terms of TCM's concept of the kidney, it includes the reproductive system and endocrine system as described in Western medicine. Insufficient function of the kidney corresponds to kidney yang deficiency, while a lack of fundamental substances corresponds to kidney yin deficiency. Especially for teenagers who are not yet fully mature, it is easier to damage their innate kidney yin. Due to insufficient kidney water, the fire of life gate associated with kidney yang becomes weak, leading to an imbalance of yin and yang in the kidneys.
