The prevalence of male infertility is rising year by year, simply because of the seed problem, the root cause is alcoholism, smoking, staying up late, long-term sedentary, etc. These are common problems of modern men. The bad habits will lead to higher sperm malformation rate, higher sperm malformation rate will increase the difficulty of natural conception, in order to father dream, male compatriots should pay attention to the health of life regular. In the 3rd edition of the WHO handbook, it is stipulated that men with normal fertility should have more than 30% of their sperm in normal form; the 4th edition of the WHO handbook stipulates that the normal form should be more than 15%; in 2010, the 5th edition of the WHO handbook stipulates that the normal form should be more than ≥4%. This shows that sperm morphology is not 100% normal as we think, and on the contrary, most of them are deformed themselves. The setting of standards has also dropped again and again, indicating that sperm malformations are increasing year by year. Even in men with normal fertility, often the rate of normal sperm morphology is only between 4-25%, which means that 75-96% of sperm will be judged to be malformed, and this portion of sperm will be eliminated from the female reproductive tract without producing the ability to conceive. Does malformation of sperm have any effect? It is mainly related to the probability of pregnancy, but not to the health of the baby after conception. The so-called “malformation” is an indicator we use to evaluate the ability of sperm to conceive, and an increase in sperm malformation will make natural conception more difficult (and will also affect the success rate of IUI and IVF). Simply put, the morphology of sperm is primarily related to the probability of pregnancy and has little to do with the nature of the sperm (genetic material). This is just as there is no direct relationship between the appearance of a person and the nature of the person, whether a person looks good or not does not indicate good or bad health, it cannot be said that a person who looks unattractive is not healthy, similarly, it cannot be said that if the sperm morphology is bad, the genetic material of the sperm is faulty and will lead to malformed babies or stillbirths. There is also no necessary link between sperm malformation and whether or not a malformed offspring is born. Therefore, the problem of male sperm malformation should not be magnified by small problems, otherwise the wrong logic will develop, that is, a lot of medication, but also little effect. Alcoholism is one of the common causes of sperm malformation It has been confirmed that alcoholism produced by alcoholism may damage sperm and cause an increase in the rate of sperm malformation, as well as sexual function abnormalities such as indifference to sexual desire, impotence and premature ejaculation. Of course refers to white wine and other strong wine, a small amount per day (no more than 50 ml is one or two) red wine or yellow wine is still beneficial. Smokers can increase the incidence of deformed sperm The more you smoke daily, the higher the incidence of deformed sperm, and the longer you smoke, the more deformed sperm you will have. It is important to note that the dangers of smoking do not stop at increasing the number of deformed sperm, but can also lead to weak sperm, cardiovascular disease, and most importantly, secondhand smoke can lead to fetal malformations. Nutritional deficiencies Zinc and selenium, the trace elements associated with sperm production and maturation, are the most important. When zinc and selenium are deficient, the hypothalamic-pituitary-gonadal axis is affected, causing a decrease in gonadotropin secretion by the pituitary gland, hypogonadism, and a decrease in sperm production, which leads to an increase in sperm malformation. Excessive temperature The testicles produce sperm and mature in the epididymis, which is suitable for a temperature of 35 to 36°C. When the temperature of the scrotum rises for various reasons, it will affect the development of sperm. For example, wearing tight underwear for a long time, sitting for a long time (driving, cycling), taking hot baths, working in a hot environment, etc. Varicocele Varicocele affects spermatogenesis, resulting in decreased sperm motility, morphological immaturity of sperm cells and an increased number of acromegalic sperm. Infections Certain infections of the urinary and reproductive system in men are also an important cause of teratozoospermia. Some of the more common infections that affect sperm malformations are prostatitis, seminal vesiculitis, urethritis, orchitis, epididymitis, etc.
