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 counts, 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. Excessive heat exposure. Such as frequent saunas, hot baths, placing laptops on the thighs, etc. The testicles are overheated and produce less sperm. 5. Prolonged bicycle riding. Those men who enjoy cycling should be extra careful because it may damage some of the sperm. In addition, some studies suggest that a variety of 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 at the groin, which is not conducive to sperm growth, thus affecting fertility; avoid high temperatures, testicular temperature is lower than other parts of the body; relax your body and mind, excessive mental stress is not conducive to sperm growth, relaxation will increase the chances of conception; eat more green vegetables and quit smoking and drinking, which can also improve sperm quality.
