Among male infertility,idiopathic male infertility(IHS)is characterized by abnormal semen analysis parameters and no clear etiology.The incidence of IHS is increasing,which brings spiritual and economic burden to domestic and even global families.Because the cause of disease is not clear,there is no effective treatment in modern medicine.Traditional Chinese medicine has advantages in the treatment of idiopathic male infertility through syndrome differentiation.Professor GUO Jun believes that the disease is based on deficiency of both kidney and spleen,laying a foundation for the formation of damp-heat in the body.The patient has been sick for a long time and has no children.If the liver-qi is not smooth,it will be stagnant.If the operation of qi,blood and body fluid is not smooth,it will be accompanied by visible pathogens such as blood stasis,damp-heat and phlegm.Therefore,for idiopathic male infertility,the treatment focuses on both reinforcing and reducing,strengthening the body and eliminating pathogens,tonifying the spleen and kidney,while for damp-heat,phlegm-dampness and blood stasis,clearing away heat,removing dampness and phlegm,activating blood circulation and removing blood stasis,etc.Examine one case at the same time.
