There are many causes of miscarriage, and the traditional view has always been that miscarriage is a woman’s business. With the development of medical science, especially male science, people have a better understanding of the possible role of the male partner in the miscarriage process: it turns out that the real cause of some miscarriages that used to be considered “unexplained” is the male partner. Men who live for a long time in an environment with high temperatures, volatile chemical gases, noise, radiation, etc., have a poorer functioning organism and greater mental stress, which affects the function of the sperm. If nodules with the egg, it may lead to miscarriage. If a man has varicocele, tumors, allergic diseases, persistent fever, etc.; or **itis, leukocytospermia, the sperm generated in this way is bound to be affected. We know that harmful chemicals can seriously endanger human health, such as benzene, mercury, cadmium, pesticides, etc. The harmful substances can be inhaled into the human blood through the lungs and can reach all parts of the body with the blood flow, which can affect the production of sperm and sperm quality, which in turn affects the growth and development of the embryo. Harmful substances can violate human nerve endings and affect human health.
