The causes of male infertility are complex, and according to their causes, Chinese medicine can be divided into several types, such as oligozoospermia, thin semen, cold semen, semen coagulation, pus semen, azoospermia, and non-ejaculation. The main cause of male infertility is the lack of sperm and weak sperm, and the lack of liquefaction of semen. The clinical and scientific research of the male department for many years recognized that “kidney yin deficiency, dampness and toxicity, qi stagnation, blood stasis, positive deficiency and evil attachment” is the main pathogenesis of this disease. The series of formulae developed from 1 to 5 “tonifying the kidney to produce sperm and invigorate blood” are based on Chinese medicine’s classic formulae and combined with macroscopic and microscopic theories to form a formula with the effects of tonifying the kidney, invigorating blood, promoting qi and relieving dampness. This series of formulas can improve the local micro-environment of sperm production, which can benefit the kidney and produce sperm. It is clinically proven that after 1 to 3 courses of treatment, it can significantly increase the number and vitality of sperm and improve sperm function.

In addition, the male department has accumulated rich clinical experience in chronic prostatitis, immune infertility, and infertility caused by varicose veins in the sperm. In terms of scientific research, he is currently undertaking the clinical research project of the Chinese Academy of Traditional Chinese Medicine (CACMSY) on the advantages and standardization of the treatment of oligozoospermia based on the kidney tonic method.
