After a romantic life before and after marriage, many young couples began to actively plan to have a new life that witnessed the love of the two.However, after one or two years of "hard work", no "Olympic Baby" and "Dragon Baby" have not come, and now the young couple can first taste the sorrow.Many domestic and foreign data showed that the disease accounted for about 10%of the married couples, while the men's factors accounted for about 40%, of which about 50%of the infertility male sperm form was abnormal.At present, the mechanism of abnormal sperm morphology has not been fully clarified, which has made some patients with deformed sperm fail to get effective treatment.
Normal sperm is less than 15%pregnancy difficulty
Wang Zhongyang, director of the Department of Urology, the Sixth Hospital of Sun Yat -sen University, said that the excessive sperm of malformations refers to a disease with excessive sperm ratio of abnormal forms.Deform sperm does not have normal activity and conception ability, which is one of the main reasons for male infertility.In addition to normal sperm, in addition to normal sperm, it also contains a certain percentage of deformity sperm. The lowest reference range of human sperm normal form is 4%in the latest WHO manual. However The morphological sperm is less than 15%, and the in vitro fertilization rate is low.
In conventional semen analysis, sperm morphology is determined that it is most valuable to predict sperm essence, but sperm morphology assessment is less likely to be accurate and stable, because human sperm itself exists in morphological diversity, and the morphology Learning testing is greater than the subjective influence of the test.The detection and count of malformation sperm shall be carried out in accordance with the recommended dyeing methods and counting methods recommended in the WHO standard, and strictly grasp the standards of normal sperm morphology and the classification standards of malformed sperm.
Disases sperm number one by one
There are many cases of sperm malformations. The first sperm head is abnormal.The main structure of the sperm head is concentrated cell nucleus and top.In the process of chromatin maturity, abnormalities can cause sperm nuclear air bubble defects in the head, that is, the probability of sperm nucleus abnormality is higher.Wang Zhongyang said that there is also a relatively rare round head sperm syndrome, which is manifested in the appearance of the sperm head.
The other is the abnormalities of sperm neck and middle.The separation of the head and tail is a common sperm connection section deformity. This deformity is also called a broken sperm.Studies have shown that most broken sperm tail structures are normal; a small part of these sperm has residual connection segments at the rear and is surrounded by cytoplasm groups, or the middle section is missing; The middle section, or the residual connection segment is connected to the main segment.Wang Zhongyang believes that excessive residual cytoplasm can cause sperm function to decrease.
Another is sperm whipped.There are two manifestations of primary cilia movement disorders and dysplasia of fibrous sheath. The former is an ingredient hidden genetic disease.Such patients are often manifested as bronchial dilatation, chronic sinusitis, visceral inverse and male infertility.The cilia or whipping structure cannot be effectively swinging is the main cause of pathogenic cause.The latter is common in severe patients. Under optical microscope, most sperm tails are short, rigid, rough or irregular.
Eat more soybean yam sperm benefits more
Wang Zhongyang said that the mechanism that affects sperm forms and caused sperm deformity has not yet been fully clear, but in general, it mainly includes several aspects such as microbial factors, physical and chemical factors, and endocrine factors.
Microbial factor.White blood cells can be seen in male reproductive tract and ejaculation.Increased white blood cell concentration in semen can lead to decreased semen quality.In addition, bacteria, mycoplasma, chlamydia, virus, etc. can also cause semen infection, which can cause semen quality (vitality, pH, form) to change.
Environmental changes include air pollution, career contact, and lifestyle habits that can affect the quality of semen.The working environment also has a significant impact on the quality of semen.History of various toxic substances is an important factor in the reduction of male fertility.Long -term contact with pesticides (such as pesticides) also has a significant impact on sperm form, resulting in a significant decrease in the normal sperm rate.In addition, some drugs (such as antibiotics, anti -cancer, and manaic drugs) can also lead to increased morphological abnormal sperm rate in male semen.
Endocrine factors.In normal male slurry, estrogen levels are significantly higher than the level of serum estrogen.This not only shows the local production of estrogen, but also suggests that the balance of testosterone/estrogen plays an important role in normal male sperm.
To protect the sperm and reduce the deformed rate, Wang Zhongyang emphasizes that in addition to reducing the hazards of tobacco and alcohol, controlling the number of times of intercourse, keeping the scrotum temperature, preventing drug damage, paying attention to the combination of labor and rest, and strengthening physical exercise, you should also pay attention to the living environment and adjust your diet reasonably. Eat more foods containing arginine, such as soybeans and products, catfish, cuttlefish, octopus, yam, ginkgo, watermelon, pumpkin, etc.
