A varicocele, or dilated complex of veins in the scrotum, can overheat the testicle(s), negatively impacting sperm production and quality. Varicocele surgery involves tying off or ligating the abnormally dilated veins, thus allowing for a healthy sperm production environment. This surgery seems to be most effective in men whose varicocele is of significant size; and in cases where sperm count and motility are not too severely impaired.
Varicocele surgery is performed under local anesthesia and light (‘twilight’) sedation, usually taking a little over an hour. The patient will return home and may be advised to take it easy for a day.
