Are you talking about an IUD?I forget what the procedure is called, but my wife had a small bit of metal inserted into her abdomen. Makes pregnancy impossible, lasts 10 years, and is removable at any time. This might be useful information for some. I don't usually give the "medicine companies only want profit" conspiracy theories, but I feel like few people have heard of this because there's no profit in a 100% effective treatment that lasts a decade.
