Is high sperm malformation rate associated with fetal malformation? Sperm malformation, also called malformed sperm, refers to the morphological variation of head, body and tail. Head malformation includes giant head, amorphous, double head, etc.; body malformation includes thick body, fracture, incomplete, etc.; tail malformation includes coiled tail, double tail, missing tail, etc. According to the standard of the fifth edition of the WHO Laboratory Test Manual for Human Semen, the normal morphology of sperm after staining is required to be above 4%. Is high sperm malformation rate associated with fetal malformation? The higher the sperm malformation rate, the higher the likelihood of infertility in many men, which means a lower chance of conception, but there is no correlation with fetal malformation. How to improve sperm quality? 1. Take a variety of vitamins. Vitamins have the role of providing raw materials for sperm, promoting sperm production, and keeping the sexual organs free from aggression. Among them, vitamin E is most closely related to the reproductive system, with a variety of roles in preventing the aging of the sex organs, regenerating the 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 food high quality protein is the main raw material for the formation of semen. The food containing high protein is lean meat, pork spinal cord, dog meat, beef and mutton, chicken and duck, eggs, fish and shrimp, soybean products, etc. Arginine is the necessary ingredient for the production of sperm, lack of which can occur less 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 the male body is overly obese, it will lead to an increase in temperature in the groin and damage 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 will be affected by other factors such as radiation, harmful chemicals (including pesticides, fertilizers, detergents, paints, etc.) and certain drugs during their production and maturation process and produce qualitative changes. Therefore, men in their reproductive years should try to avoid long-term exposure to large amounts of such harmful substances and do not abuse drugs at will.
