The first reaction of many patients when they get the report of sperm morphology is that they have made a mistake, why is my sperm morphology so little normal and the proportion of abnormalities so high? Deformed sperm refers to the morphological variation of head, body and tail. Head deformities include giant head, amorphous, double head, etc.; body deformities include thick body, fracture, incomplete, etc.; tail deformities include coiled tail, double tail, missing tail, etc. Sperm morphology is examined by smearing and staining the semen and then placing it under a microscope to observe sperm morphology one by one: the morphology of normal sperm. The head is ovoid on the front, flattened on the side, and the tail is long and curved, shaped like a tadpole. An excess of immature sperm, senile sperm and malformed sperm can interfere with normal fertilization and have a negative correlation effect with fertility. The fertilization ability of sperm is closely related to the normal morphological structure of sperm, and the greater the number of sperm with normal morphological structure, the greater the fertility. Causes of disease 1. Genitourinary system infection: Genitourinary system infection is an important factor leading to sperm malformation. Due to the occurrence of urogenital infections, the nutrients in the semen will be reduced, making the sperm deformed or dead. 2, endocrine disorders: the body of certain related hormone secretion imbalance, resulting in an increased rate of deformation. 3, excessive smoking: a new study found that smokers can make the incidence of deformed sperm significantly higher. The longer the smoking time, the more deformed sperm. 4, alcohol abuse: alcohol abuse is also a common cause of sperm malformation. Alcoholism produced by alcoholism may damage sperm and cause an increase in sperm malformation, and may also cause sexual indifference, impotence, premature ejaculation and other abnormalities of sexual function. 5, other causes: chemical agents, radiation, environmental pollution and other factors, can trigger sperm malformation. 6, disease factors: genitourinary tract infection, mumps complications of orchitis, epididymal tuberculosis, varicose veins of the spermatozoa and so on, these diseases can affect the quality of sperm and the formation of deformed spermatozoa. 7, drug factors: the use of hormones or certain chemical drugs, can make sperm immature, the formation of deformed sperm, resulting in deformed sperm disease. 8, external factors: external factors such as radiation exposure of the gonads can also cause mutations in sperm and the formation of deformed spermatozoa. Will a high sperm malformation rate give birth to a fetal malformation? Fetal malformation and sperm malformation are not the same thing. Sperm malformation is only abnormal in shape and affects the ability to fertilize. It is the intrinsic quality of the sperm that is the main factor affecting the quality of the embryo and the miscarriage. A high sperm malformation rate alone will not lead to an increased fetal malformation rate, but it is the presence of viral infections, reproductive tract infections, chromosomal abnormalities and other diseases in some patients with teratozoospermia that will cause an increased fetal malformation rate. How is teratozoospermia treated? It takes at least three months for sperm to form, so the preparation period should be at least three months in advance. At the same time, the treatment effect varies with each patient due to various factors such as occupation and lifestyle habits. It is recommended to pay attention to the adjustment of living habits; prohibit smoking and alcohol, avoid spicy diet; reduce the exposure to chemicals and so on; be careful with the use of complementary treatment, etc. The treatment of the disease is a slow process, do not be too anxious and indiscriminate treatment, affecting the effectiveness of treatment!
