Vasectomy is a method of permanent male sterilization. It is a surgical procedure in which a cut is made in the vas deferens to prevent the passage of spermatozoa. For this reason, when a vasectomized male undergoes a semen analysis, no spermatozoa can be seen and the sperm count is, therefore, zero.
