After unilateral spermatic vein surgery, there are usually no major contraindications in terms of diet, patients can just eat normally and pay attention to nutrition. Eat laxative food early after varicocele surgery, such as fruits containing more fiber, such as watermelon, apples and bananas, etc. These fruits can improve constipation at the same time, and reduce the incision pain caused by the difficulty of defecation and straining to defecate after surgery. In severe cases, patients can be treated with surgery. High level ligation of spermatic vein can effectively block the reflux of renal vein, which can help patients to recover the function of testicular spermatogenesis and enhance the function of interstitial cells to secrete androgens, and it can improve the symptoms of localized swelling and pain after the surgery, and improve the quality of sperms. The efficacy of laparoscopic high varicocele ligation is reliable, and the preservation of the internal spermatic artery can reduce the incidence of postoperative complications. Meanwhile, high-quality protein diet, such as milk, meat and other protein-rich foods, strengthens the body’s immunity and promotes incision healing. After the surgery, we usually avoid eating cold, hard and irritating foods to prevent the incision from becoming congested and inflamed.
