After the single two-child policy was liberalized, many families entered the “pregnancy preparation” army, and careful couples even began to do pre-conception tests. It turns out that some husbands’ sperm “fail”, or sperm count reduction, low mobility, increased malformation rate and poor semen liquefaction, environmental pollution, radiation, poor dietary habits, smoking and alcohol abuse are important reasons. “The sperm reduction is, in the opinion of Chinese medicine, a result of the loss of kidney essence and weakness of the vital gate. Regular moxibustion of the vital gate point with ginger has the effect of warming the kidneys and strengthening the yang and improving sperm quality. The vital gate point belongs to the Directing Vessel and is located between the two kidneys, and is the place of the vital gate, the birth gate for women and the sperm gate for men.

The kidneys need to be warmed up by the fire of the vital gate, so that the kidney essence is sufficient to nourish the internal organs of the body and reproduce offspring. The moxibustion of the vital gate with ginger and moxa leaves is to use the power of ginger and mugwort to dispel cold with the vital gate point to strengthen the yang in the body and achieve the effect of warming the kidneys and strengthening the yang, benefiting the qi and cultivating the yuan. Clinical studies have shown that moxibustion with ginger can effectively improve sperm morphology and liquefaction time, increase the number of sperm and enhance their motility, and improve the function of pregnancy and fertility. It can also be used to treat spermatorrhea and premature ejaculation due to kidney deficiency, impotence due to failure of the vital gate fire and deficiency of essence due to coldness, women’s deficiency of kidney energy and deficiency of the lower yuan, and lumbago due to kidney deficiency and dampness.
