Semen overflow is not equal to kidney deficiency. Semen overflow is clinically known as sperm overflow, which is a physiological phenomenon commonly seen in sleep, and is due to the fact that the semen reaches a certain amount and is in a saturated state, it will be discharged by way of seminal emission. For example, if an adult male does not have sex for a long time and does not usually masturbate, seminal emission can occur 1 to 4 times per month. However, if spermatorrhea is too frequent (more than 2 times a week), accompanied by accompanying symptoms such as lumbar and knee soreness (a feeling of soreness and weakness in the lumbar and knee areas), irritability and heat in the hands and feet (irritability and sultriness), or coldness in the hands and feet, it may belong to the category of jingguan unsoundness (deficiency of the kidneys, the kidneys can not hide the sperm), and the kidneys have lost their sealing and storing, which leads to the deficiency of kidney yin or renal yang (lack of yang qi in the kidneys). In summary, occasional spermatorrhea is generally not a cause for concern, but if the above symptoms occur, it is necessary to consult a doctor in a timely manner to clarify the cause and provide targeted treatment.
