What is Wrong With Sterilisation?
When sterilisation is carried out to save the health of an individual, it is licit. However, direct sterilisation has the immediate purpose of making reproduction impossible and it is always immoral. Direct sterilisation is the only surgery (apart from abortion) that deliberately destroys the natural functioning of healthy organs. Contrary to popular opinion, there are serious health risks involved, eg vasectomy is linked with renal disease (The Lancet, 1, No2, 1988).
