In addition to having an important impact on the development of the fetus, the quality of the father's sperm also affects the development of fertilized eggs and even the growth of the fetus.Most people often only notice the role of women in the descendants, because the fertilization and development of eggs are carried out in the mother's body, so they believe that the mother's responsibility is great.As everyone knows, the role of dad is also very important, especially the quality and quantity of semen, which is also important for the impact on future generations.
Sperm quality is important
In addition to the completion of fertilization, in addition to egg cells, the number, quality, and activity of sperm plays an important role, and the quality of sperm is particularly important.The man's physical fitness, the health and function of reproductive organs, and certain external environmental factors all affect the quality and quantity of sperm.There are less than 1.5 ml of semen each time, less than 20 million sperm, sperm malformation rates exceeding 20%, sperm mortality exceeding 50%, sperm activity is less than 60%, semen is not liquefied within half an hour, etc.Both can cause infertility.
Director Shi Changchun, an expert in Beijing Tianlun, pointed out that some patients often encountered some patients in clinical practice. After the treatment of females, the problem has basically been solved, but it is still difficult to become pregnant. As a result, there is a problem with the men's semen.Some factors in vivo and in vitro can cause sperm production defects, which causes the man to have infertility, or cause the defects of future generations.At least 85%of male infertility patients in clinical practice are the defects of sperm itself. The main reasons are: (1) congenital factors, such as testicular development disorders or incomplete maturity, and chromosomal abnormalities; (2) endocrine diseasesFor example, pituitary, adrenal, and thyroid diseases cause testicular spermatogenic dysfunction; (3) infection diseases caused by various inflammatory reproductive systems; (4) radiation radiation;Pants, which make the testicles pressing to the groin tube and increase the testicular temperature, causing testicular sperm functional decline; (6) chemical poisoning and application of the application of essential drugs, such as Malilan, Fufu drugs and long -term use of testosterone, estrogen,,,, estrogen,,,,, estrogen,,,,, estrogen,,,,, estrogen,,,,, estrogen,,,,,,Wilderness; (7) Long -term chronic diseases and nutritional deficiency; (8) immune sudden ejaculation caused by testicular damage;
Animal experiment research confirms that taking sedatives has the effect of male animal sperm malformation and affects the health of future generations.Therefore, before pregnancy, before wanting the child's sex life, it is possible that the man's medication can cause congenital defects in the offspring.Some scholars believe that certain chemical preparations can damage the production and maturity of sperm cells, affect the quality of male semen, and the transmission of sperm and its decomposition products to sperm.In addition, men are in chronic diseases, such as malnutrition, lack of vitamin A and calcium, phosphorus, etc., severe hobbies of tobacco and alcohol, benzene, lead, and arsenic poisoning will also affect the quality of sperm.
Therefore, for the next generation of health, men should avoid conceiving their wives under the above unfavorable conditions.To improve physical fitness, quit the hobbies of tobacco and alcohol, and take drugs with caution, so as to create a suitable pregnancy condition to ensure a strong baby.Sperm is vulnerable to injury
From the perspective of sperm biological characteristics, sperm is the terminal product of the development of the male germ cell line.In the process of sperm, formation, and deformation, due to cytoplasm removal, DNA repair enzymes in cytoplasm are lost, which causes DNA damage and repair system functions to be lost.Therefore, it cannot repair more than 90%of primary genetic material damage by itself like body cells and egg cells.Among the various cells of the human body, only sperm has this characteristic.In addition, sperm is more sensitive to toxic substances compared to various other cells.Sperm cells are always in a rapid division, and men will continue to generate sperm from the middle and late stages of embryo to old age.In the process of rapid sperm, the harmful effects of various harmful factors have increased significantly after accumulation and accumulation.With the deepening of genetic research and understanding in recent years, people have become more clear. Compared with X chromosomes in the eggs, the genes of Y chromosomes in sperm are more likely to change.
