Vasotomy is a surgical incision into the vas deferens. This is usually done for diagnostic or therapeutic purposes, such as to retrieve sperm for fertility treatments or to relieve a blockage. It is less common than a vasectomy, which involves cutting and sealing the vas deferens. Think of it as making a small opening in the tube, rather than cutting it completely. This allows doctors to access or treat the vas deferens without permanently altering it.
