Varicocele comes in 3 grades. Grade 1 varicocele is not clear to a person. It is only diagnosed via an ultrasound examination. The same applies to grade 2 varicoceles. They are also diagnosed via an ultrasound examination of the scrotum. A grade 3 varicocele is obvious. A person or a doctor can see and feel the abnormally large varicose veins within the scrotum.
