A vasectomy is a procedure that a man undergoes as a form of permanent birth control. In this procedure, the vasa deferentia is severed in the man. Both married and unmarried men are choosing this option in order to make sure that they are not at risk of becoming a father when they do not want to be one or simply don't want more children than what they have.
For those without the proper health insurance coverage for this, the procedure can be a little expensive, especially in the United States. This is why more and more men are opting to travel to other countries to have the vasectomy done. There is very little risk involved with this procedure, many find that the countries with the best rates are appealing.
