There are many precautions for varicocele, such as avoiding strenuous exercise and prolonged standing, avoiding high local temperature of testicles, controlling body weight and so on. 1. Avoid strenuous exercise and prolonged standing: patients with varicocele should avoid strenuous exercise as much as possible, and at the same time reduce the time of standing, and choose to lie down when resting, so as to increase the amount of return blood and relieve the varicose veins of the spermatic cord. 2. Avoid high local temperature of testicles: When the temperature of testicles increases due to various reasons, and the blood return is reduced due to the sagging of scrotum, some patients may experience the aggravation of varicocele. 3. Weight control: too much weight can aggravate varicocele because too much abdominal fat compresses the veins and leads to poor blood flow. There are many other precautions to be taken for varicocele, and it is recommended that such patients go to regular hospitals for consultation and active treatment.
