Although the sperm is small, it has a great crossing ability.It can penetrate cervical mucus and keep swimming in women's fallopian tubes.A healthy adult man can produce hundreds of millions of sperm each time ejaculation, but not every sperm is "brave and good.""The number of sperm is amazing, but the life is fragile." The chief physician of Guo Jun, chief physician of the male department of Xiyuan Hospital of the Chinese Academy of Traditional Chinese Medicine, said that sperm vitality is commonly used in medicine to evaluate the quality of semen, which mainly refers to the percentage of sperm sperm in semen.Sperm vitality is mainly affected by the following aspects.
1. Age.Generally speaking, male sperm vitality changes with parabola with age, of which 20 & mdash; 40 years old is the best vitality, that is, the "golden period" of men.After the age of 40, men's sperm vitality will decrease at a rate of 0.7%per year, and more and more deformed sperm will be. After 60 years of age, 85%of sperm may be deformities.
2. Smoking and drinking.The impact of smoking on sperm vitality is very great. Foreign studies have shown that the main indicators of semen quality are significantly reduced compared with non -smoking persons, and sperm malformation rates have also increased significantly.Alcohol has a direct impact on men's testicles. Long -term drinking will cause testicular atrophy and sperm quality.
3. Exercise.Studies have found that excessive obesity of men will lead to increased temperature at the groin and damage sperm growth.A moderate amount of exercise can help improve sperm vitality and balance the level of body hormone, especially maintaining the secretion level of male hormones.However, severe exercise, such as marathon and long -distance cycling, may still affect the growth environment of sperm.
4. Temperature.Long -term wearing tight pants, steaming sauna, soaking in hot bath, putting laptops on legs and other habits will cause poor local heat dissipation, cause the temperature of the scrotum to increase the temperature, thereby reducing the production and vitality of sperm.
5. Cosmetics.Some of the substances contained in cosmetics also affect sperm vitality, mainly deotonate and estrogen.The former is the recently dazzling plasticizer. There are such substances in food or cosmetics, which will interfere with endocrine, reduce the number of male sperm, low sports ability, and abnormal morphology, trigger changes in testicular tissue structure, and reduce the number of sperm in semen.
