Sperm deformities, also called malformed sperm, refer to morphological variations of the head, body and tail. Head deformities include giant head, amorphous, double head, etc.; body deformities include thick body, folded, incomplete, etc.; tail deformities include coiled tail, double tail, missing tail, etc. In a statistical sense, when a normal reference value is very close to 0, it is already difficult to distinguish the normal and pathological range of results with such a low reference value because the biological reference value cannot be negative, and thus it is difficult to distinguish the normal fertility from the infertile population. The spermatozoa are not only the most common type of spermatozoa, but also the most common type of spermatozoa. The higher the sperm malformation rate, the higher the possibility of infertility in many men, which means a lower chance of conception, but there is no clear correlation with fetal malformation, and teratospermia does not necessarily lead to fetal malformation. Because the female reproductive tract has a function of superiority and inferiority, the sperm will eliminate most of the deformed sperm in the process of passing through the female reproductive tract, thus excluding the possibility of the combination of deformed sperm and egg, and ultimately ensuring the quality of the sperm for conception. 2. What are the causes of deformed spermatozoa? The causes of deformed spermatozoa include varicocele, genitourinary tract infection, testicular inflammation complicated by mumps, epididymal tuberculosis, etc. All these diseases can affect the quality of sperm; the use of hormones or certain chemical drugs, such as anticancer drugs, reserpine, Maryland, furans, etc., can make the sperm immature and abnormal; the gonads are exposed to radiation and irradiation, which can cause mutation of sperm; the scrotum local long-term High fever, long-term alcoholism and smoking, as well as chromosomal abnormalities can cause sperm aberrations and lead to an increase in malformed sperm. Varicocele is the most common cause of malformed spermatozoa. 3.What are the causes of malformed fetus? Deformed fetus may be caused by internal factors (such as chromosomes, genes, etc.) or external environment (such as viruses, toxoplasma, mycoplasma, chlamydia, iodine deficiency and endemic cretinism, heavy metals such as lead, mercury and benzene, fluorosis, radiation, radiation from household appliances, computers and cell phones, air pollution, food pollution, diseases and drugs, etc.), or it may be the result of a combination of these two types of factors It is more likely to be the result of a combination of these two types of factors. 4.How to improve sperm quality? (1) Supplementation of various vitamins. Vitamins have the role of providing raw materials for sperm, promoting sperm production, and keeping the sexual organs free from abuse. Among them, vitamin E is most closely related to the reproductive system, with a variety of roles in preventing the aging of sex organs, regenerating empty vas deferens, and enhancing sperm vitality. Vitamin E-containing foods are mostly destroyed during processing, so preparations can be taken, such as vitamin E pills. Other vitamins are rich in popular vegetables; (2) eat high quality protein and arginine foods high quality protein is the main raw material for the formation of semen. The food containing high protein include lean meat, pork spinal cord, dog meat, beef and mutton, chicken and duck, eggs, fish and shrimp, soy products, etc. Arginine is a necessary ingredient for the production of sperm, and can occur when lacking in spermatozoa. The food containing arginine are eel, black fish, sea cucumber, hoof tendons, soy products, lean meat, etc.; (3) less to sauna, steam bath. High-temperature steam baths directly harm sperm, but also inhibit sperm production; (4) participate in more physical exercise. Studies have shown that if a man is overly obese, it can lead to an increase in temperature in the groin, which impairs the normal growth of sperm, which can lead to infertility problems. Therefore, weight control within the standard range can improve the quality of sperm; (5) avoid the influence of harmful substances. The sperm in the testicles are affected by other factors such as radiation, harmful chemicals (including pesticides, fertilizers, detergents, paints, etc.) and certain drugs during their production and maturation process, which can lead to qualitative changes. Therefore, men in their reproductive years should try to avoid long-term exposure to a large number of such harmful substances and do not abuse drugs at will. The doctor suggests: 1, before preparing to have a child must go to the regular hospital male, reproductive medicine department to do a pre-conception examination, found in time to treat the problem; 2, can be natural or after treatment can be natural conception, never advocate the use of assisted reproductive technology conception, in order to ensure the natural elimination of genetic defects, so as to ensure the natural health of the offspring; 3, after pregnancy should avoid all factors that may lead to fetal malformations, especially those pregnant women who are of advanced age and work in high-risk industries. Oral folic acid tablets (0.4 mg/day) can be taken during the first 3 months of pregnancy.
