Varicose veins can affect sperm if they are varicose veins of the spermatozoa. Because sperm are easily affected by blood nutrition and temperature, if varicose veins are present, it will lead to impaired blood circulation around the testicles, and long-term varicose veins will lead to increased local temperature of the testicles, which will affect the quality of sperm. Therefore, varicocele can affect the quality and quantity of sperm, so it can lead to male infertility. If you want to completely remove the effect of varicocele on sperm, you have to undergo surgical treatment in various ways, and you need to choose different surgical procedures according to the patient’s different conditions and according to the patient’s needs.
