Men standing for long periods of time can damage their sperm

　　Many people know that sitting for long periods of time is not good for male reproduction healthy , may harm sperm . In fact, standing for a long time is also not good for men's health. In particular, men who work as teachers or in service industries need to pay more attention.

　　Just like sitting for a long time, standing for a long time can easily lead to poor venous blood return in the testicles and stay in the blood vessels, causing obstruction of the spermatic vein in the scrotum. It may also produce abnormal swelling and lead to varicocele. Some people will experience soreness in the testicles, inner thighs, groin and waist due to this. In severe cases, protruding blood vessels can be seen from the appearance. This may also affect male fertility, because blood retention in the spermatic vein will increase the local temperature of the testicles and prevent metabolic waste from being taken away in time, resulting in the testicles not being adequately nourished. ； At the same time, the blood in the left internal spermatic vein flows backward, bringing the metabolites secreted by the adrenal glands and kidneys to the testicles, inhibiting sperm production and affecting sperm quality and quantity. If this happens for a long time, it will even affect testicular function, leading to testicular softening and smaller size.

　　Therefore, men who need to stand for long periods of time should walk around or sit down to take a break every hour. If you suspect that you have varicocele, you can observe yourself first. If you cannot see varicose veins after standing and holding your breath, but you can feel the varicose veins, it is considered mild. ； If the vein mass can be seen and felt, and the mass can gradually disappear after lying down, it is considered moderate. ； The obvious vermiform veins can be seen with the naked eye and palpated, and they disappear very slowly even when lying down. Severe cases are considered severe. Generally speaking, those with no symptoms or mild symptoms can only use a scrotum support belt or wear tight underwear to raise the scrotum. If you have severe pain symptoms, you must seek medical treatment promptly.
