What factors lead to male infertility? The main causes of male infertility are low sperm quantity, high sperm deformity rate or poor mobility, ejaculation dysfunction or obstruction of semen output duct. So what factors lead to male infertility? Here is your introduction.
1、 Vulnerable sperm
From the biological characteristics of sperm, sperm is the terminal product of the development of male germ cell line. In the process of spermatogenesis, formation and deformation, due to the escape of cytoplasm, DNA repair enzymes in cytoplasm are lost, resulting in the loss of DNA damage and repair system function. Therefore, it can not repair more than 90% of the primary genetic material damage by itself, like somatic cells and egg cells. Among all kinds of human cells, only sperm has such characteristics. In addition, compared with other kinds of cells, sperm is more sensitive to toxic substances. Spermatogenic cells are always in a state of rapid division, while men will continuously produce sperm from the middle and late stages of the embryo to the old age. In the process of rapid spermatogenesis, the harmful effects of various harmful factors increase significantly after accumulation and accumulation. With the deepening of gene research and understanding in recent years, it is more clear that the gene carried by Y chromosome is more prone to mutation than that carried by X chromosome.
2、 What factors cause male infertility
In addition to genetic and organic diseases of some organs, male infertility is closely related to living habits. If these bad habits can be understood or overcome in daily life, at least the occurrence of male infertility can be reduced or avoided, then what factors can cause male sperm reduction and infertility?
1. Disordered and unclean sex life
Disordered and unclean sexual life is easy to cause male genital tract infection. Pathogens causing genital tract infection include gonococcus, mycobacterium tuberculosis, virus, mycoplasma, chlamydia and trichomonas, among which mycoplasma and chlamydia infection are the most common. Reproductive tract infection first affects sperm production and sperm transport, resulting in oligospermia and reproductive decline. Genital tract infection can also cause changes in sperm vitality. Genital tract infection can inhibit the secretion of accessory gonads, resulting in insufficient secretion of semen, nutrient deficiency of semen, changes in acidity and alkalinity, and changes in semen composition, thus affecting the growth environment of sperm, causing a serious decline in sperm vitality and quantity, resulting in infertility.
2. Smoking and drinking
Men are quite sensitive to the toxins in tobacco and alcohol, especially the germ cells. According to research, nicotine in tobacco leaves can reduce the secretion of sex hormones and kill sperm. For those who smoke 30 cigarettes a day, the sperm survival rate is only 49%, and the secretion of male hormones in smokers is 16% to 47% less than that in non-smokers, thus reducing the ability to produce sperm. Long-term alcoholism will damage spermatogenic cells of testis and affect sperm production.
3. Damage of warm environment to testis
For example, long-term high-temperature operation, hot water bath, and wearing tights for a long time will hinder the function of scrotum to regulate temperature. Many men wear tights for a long time in order to show a good figure. However, tights will firmly stick the scrotum and testicles together, making the heat dissipation function of the scrotal skin unable to play, thus increasing the local temperature of testicles and hindering sperm production. In addition, wearing tights will also limit and hinder the blood circulation at the scrotum, forming testicular blood stasis, leading to infertility. The testicle is the organ that produces sperm. The temperature of the testicle during spermatogenesis must be between 35.5 ℃ and 36.5 ℃, which is 1 to 1.5 ℃ lower than the normal temperature. Often take a bath with very hot water, especially a bath in a tub or sauna, so that the scrotum is often in a high temperature state, which will affect the spermatogenic function of the testicle.
4. Improper diet
Nutritional deficiency, such as vitamin a deficiency, can lead to the growth of spermatogenic epithelium; Vitamin b deficiency can affect pituitary function and reduce fertility; Vitamin c plays an important role in preventing sperm coagulation and maintaining sperm vitality; Vitamin e deficiency can cause testicular damage; Lack of calcium and phosphorus can reduce fertility; The lack of trace elements zinc and magnesium will also have a greater impact on the production and vitality of sperm. In addition, gossypol in edible crude cottonseed oil can destroy spermatogenic cells and cause infertility; Eating too much celery can also cause infertility. After 10 years of research, a Thai doctor has proved that celery has the effect of contraception. After the men in the test eat 75 grams of cooked celery every day for 1 to 2 weeks, the number of sperm in these men will be significantly reduced, that is, from the normal sperm content per milliliter to only 3000 per milliliter, which is difficult for women to conceive.
3、 Food for replenishing sperm
1. Eating foods rich in vitamins can replenish sperm
Vitamins A, B, C, E, etc. are indispensable important substances for providing raw materials for sperm and semen, promoting the synthesis and metaplasia of sperm, regulating the function of gonads, enhancing sperm vitality, protecting the anti-infection ability of paragonads, and maintaining the whole metabolic process of sperm. These vitamins are widely found in animal liver, vegetable oil, green leafy vegetables and carrots, peas, tomatoes, lentils, lettuce, cauliflower, pumpkins, potatoes, sheraton, kale, garlic, dates and fresh fruits.
2. Eating foods rich in zinc can replenish sperm
It can be said that there are many trace elements for male reproductive function, and zinc is the main trace element for sperm production and maturation, which is the key to ensure sperm quality. Some men have too little sperm. This is what we often call asthenospermia. It not only depends on drug treatment, but also can be cured by daily diet.
