Varicocele not only occurs in people's lower limbs, but also in men, especially men who sit and stand for too long. Statistics show that about 10% of men aged 30-40 are prone to this disease, among which male teachers, salespeople and waiters who are characterized by standing for a long time are the most common. Because men stand and sit for too long, it is easy to cause spermatic vein obstruction and abnormal swelling, that is, testicular venous blood is not smooth and stays in blood vessels. After a long time, the patient may have pain in the testicles, inner thighs, groin and waist, or the testicles may soften and become smaller. In severe cases, prominent blood vessels can be seen from the appearance, which seriously affects the male fertility. According to foreign research, the content of free radicals in patients with varicocele is twice that of normal people, but the antioxidant capacity is only 1/2 of normal people. Excessive free radicals will lead to cell aging and canceration, and increase the incidence of cardiovascular diseases and cataracts. Therefore, doctors usually advise male patients to avoid sedentary, long standing, moderate rest and exercise to improve their anti-aging ability. In addition, when men take a hot bath, they can also check themselves at any time to see whether the testicles on both sides are symmetrical and whether there are earthworms or noodle-like protrusions. If you have symptoms of soreness, you should seek medical attention immediately. Usually, patients with mild symptoms can be treated with drugs, and patients with severe symptoms can consider vein ligation. About 40% patients can improve the symptoms of infertility after operation.
