For healthy men, the number of sperm in each semen is very large, about hundreds of millions of sperm. With such a large number of sperm, it is rare to have one that can truly survive. What are the factors that affect sperm quality? From this, we can know the causes of male infertility.
There are many factors that affect sperm quality, and perhaps many men are unaware that their bad habits can also cause unimaginable harm to sperm. The specific introduction is as follows.
Age.
Generally speaking, male sperm motility changes in a parabola with age, and 20-40 years old is the best time for its vitality, which is also the "golden period of fertility" for men. After the age of 40, the sperm motility of men will decline at an annual rate of 0.7%, and there will be more and more deformed sperm. After the age of 60, 85% of the sperm may be deformed.
Smoking and drinking.
Smoking has a great impact on sperm motility. Foreign studies have shown that compared with non-smokers, smokers have significantly reduced the main indicators of semen quality, and sperm deformity rate has also significantly increased. Alcohol has a direct impact on male testes, and long-term excessive drinking can lead to testicular atrophy and a decrease in semen quality.
Exercise.
Research has found that excessive obesity in men can lead to an increase in temperature in the groin and damage sperm growth. Moderate exercise can help improve sperm motility, balance body hormone levels, especially maintain the level of androgen secretion. However, vigorous exercise, such as marathons and long-distance cycling, may still affect the growth environment of sperm.
Temperature.
Long term habits such as wearing tight pants, steaming saunas, soaking in hot baths, and placing laptops on the legs can lead to poor local heat dissipation, causing an increase in scrotal temperature, thereby reducing sperm production and vitality.
Cosmetics.
Some substances contained in cosmetics can also affect sperm motility, mainly phthalates and estrogen. The former is the plasticizer that has been making a lot of noise recently. The presence of such substances in food or cosmetics can disrupt the endocrine system, reduce the number of male sperm, reduce their motility, and cause abnormal morphology, leading to changes in testicular tissue structure and reducing the number of sperm in semen.
Therefore, in order to improve sperm motility, we should start from the above aspects, such as taking more physical exercise, less sauna, smoking and drinking. British fertility expert Winster pointed out that sperm growth only takes 4 months, and by changing lifestyle habits, the quantity and quality of sperm can be immediately improved.
