High-quality sperm is the basis for the origin of life. In recent years, sperm counts have been decreasing in men around the world, which is not only a matter of male health, but also a sign that human reproductive capacity may be at risk. A recent study on sperm counts concluded that men who watch more than 20 hours of television per week have significantly lower sperm counts, which has caused many people to become panicked about television. In fact, the decrease in sperm count is related to environmental lifestyle and other factors, but is not directly linked to television viewing. There are five environmental factors that have been shown to reduce sperm count, including: 1. Industrial chemicals. For example, benzene, herbicides, pesticides and certain painting materials. 2, Heavy metals, especially lead. 3, Radiation or X-ray exposure to the pelvic area. 4.Exposure to excessive heat. Such as frequent saunas, hot baths, placing laptops on the thighs, etc. The testicles are overheated and produce less sperm. 5, long time riding a bicycle. Those men who like cycling should be extra careful because it may damage some of the sperm. In addition, some studies have concluded that various diseases such as varicocele can also affect sperm count. Infections, especially STD infections such as chlamydia and gonorrhea, can also reduce sperm motility. To improve sperm quality, physical exercise should be increased appropriately. Excessive obesity in the male body can lead to increased temperature in the groin, which is not conducive to sperm growth and thus affects fertility; avoid high temperatures, the testicles are cooler than other parts of the body; relax, excessive mental stress is not conducive to sperm growth and relaxation will increase the chances of conception; eating more green vegetables and quitting smoking and drinking can also improve sperm quality.
