Oligozoospermia in men is a common cause of male infertility or reduced fertility. Its harm is mainly reflected in affecting conception, affecting eugenics, and causing premature birth or miscarriage, so oligozoospermia should be given enough attention. The factors that cause oligo-weak spermatozoa are relatively numerous, and whether they cause infertility depends on the degree of oligo-weak spermatozoa and its specific causes. The main causes of less and weaker spermatozoa are the following: 1, inflammation of the epididymis, seminal vesicles, prostate and other organs cause seminal plasma variation, affecting sperm activity and survival, such as prostatitis, orchitis, etc. 2, varicocele, testicular local lack of oxygen due to venous blood return obstruction, causing reduced sperm motility. 3.Trace element deficiency affects sperm motility. 4, testicular development is hindered, testicular spermatogenic epithelium is not fully mature or damaged and thinned, resulting in poor sperm quality and reduced viability. Such as radiation, high temperature, drug effects (sulfa drugs, Antiseptic, cyclophosphamide, aminopterin, colchicine, etc.), alcoholism, alcoholism, smoking, etc. 5, the amount of semen is not enough to affect sperm activity. Such as excessive room strain, fatigue subhealth, etc. 6, the body produces anti-sperm antibodies, so that sperm agglutination or braking. Such as some inflammation, trauma, vasectomy and other surgical damage to the blood-testis barrier immune response occurs, generating its own anti-sperm antibodies. Other special types are idiopathic oligospermia, such as gonadotropin deficiency, low testosterone, hypogonadism, or long-term massive injection of androgen negative feedback inhibition. There are chromosomal abnormalities, chromosomal aberrations, especially sex chromosomal aberrations, which seriously affect semen quality, etc. Treatment, few, weak spermatozoa, the focus should be clear etiology, the combination of Chinese and Western, complementary advantages is the treatment method. Western medicine mainly to identify the cause, the cause of symptomatic treatment: such as varicocele, cryptorchidism is timely surgical treatment; reproductive tract infection to actively anti-inflammatory; anti-sperm antibodies can try immunosuppressive drugs such as adrenal glucocorticoids and high dose vitamin C treatment. For endocrine factors, Western medicine endocrine therapy should be performed, and zinc and vitamin E should be supplemented for lack of trace elements. For idiopathic oligospermia of unknown etiology, testosterone or synthetic testosterone derivatives can be used for treatment. However, the incomparable advantages of Chinese medicine in terms of overall identification should always be brought into play. The advantages of “dialectical treatment” in Chinese medicine Chinese medicine has a complete medical system of “dialectical treatment”, including “theory, method, prescription and medicine”. The clinical use of drugs and prescriptions must conform to the requirements of the treatment rules, and the establishment of the treatment rules depends on the guidance of the “theory” of dialectical treatment. Chinese medicine believes that the main cause is the dysfunction of the kidney, liver, spleen, heart and other viscera, congenital deficiency, and loss of nourishment. The pathogenesis is “kidney deficiency, damp-heat, stagnation”, the nature of the disease is “actual deficiency mixed”, focusing on the three organs of the kidney, liver and spleen, the treatment is “tonifying the kidney and benefiting the essence, moving Qi and blood, clearing heat and dampness”. Therefore, the formula must comply with the principle of “ruler, minister, adjuvant and ambassador”, distinguish the main and secondary, and reasonably group the prescriptions to achieve diagnosis and treatment, add and subtract according to the symptoms, treat both the symptoms and the root cause, and attack and supplement at the same time, do not deficiency. Clinically, we often use Cuscuta sinensis, Fructus Lycii, Fructus chasteensis, Fructus Mercurialis, etc. to nourish the kidney and benefit the essence. For example, the deficiency of kidney qi can be reduced by Huang Jing Zan Yu Tang and Wu Zi Yan Zong Wan; the lack of kidney essence can be added to Qi Bao Mei Zhu Dan; the weakness of the spleen and stomach can be added to the supplement Zhong Yi Qi Tang; the damp heat is contained in the evidence of Dioscorea Z Fen Qing Drink, and the stagnation of the essence complex has been added to Tao Hong Si Wu Tang. Prevention and care: 1, to develop healthy habits, pay attention to physical exercise, pay attention to hygiene, regular sex life, reduce staying up late, etc.. 2, wear more loose and breathable underwear and outer pants. Less hot water bath or sauna, hot springs. Stay away from high-temperature places such as refineries and boilers, and avoid contact with chemicals such as dry cleaning clothes. 3, you can use an ice pack to cold compress the scrotum for 3-4 hours every night for 2 months. 4, less spicy stimulation, fatty sweet fried, tobacco and alcohol, avoid foreign fast food, cola and other carbonated beverages, cottonseed oil, etc. 5, medicine and food, more yam, wolfberry and other flat tonic herbal ingredients. 6, eat more zinc, arginine food. Arginine-rich foods include soybean products, ginkgo, sea cucumber, cuttlefish, octopus, watermelon, pumpkin, etc. Avoid eating sperm-killing celery, green beans, etc. In short, for male infertility, especially for unexplained infertility, it is more important to take comprehensive care; if there is no typical condition or the pursuit of eugenics, then pay attention to the Chinese medicine way of nourishing essence, as the so-called “to seek a heir must first nourish the essence, it is advisable to abstain from labor, not to deplete its mind, to nourish the blood and regulate the essence; it is advisable to abstain from alcohol, not to use alcohol as a sex medium, so as to avoid the fetus is not solid; it is advisable to clear the mind, not to help the fire with medicine, to calm the mind and cherish the essence It is advisable to restrain anger, not to anger injury to the liver and fire, in order to nourish Yin and suppress fire; it is advisable to be cautious of taste, not to crave fatty and thick taste, to light taste diet treatment to nourish the essence.”
