Having the operation of a vasectomy in our waking life renders males incapable of producing offspring. If a vasectomy appears in your dream life, this symbol implies that you might be cutting off opportunities in your life. If you are a man and experience this dream you may be feeling loss of control over some area of your life, probably your sex life.
You also may be simply dissatisfied with the state of your sex life when this dream symbol appears. If the vasectomy symbol appears in your dream and another person is also in this dream, the symbol could be suggesting that this person does not allow you to show the world who you really are, and are restricting your freedom or restricting you in this relationship.
