Once a woman has decided to no longer have children, instead of using temporary measures, she can choose Essure, a form of permanent contraception. This is a one-time minimally invasive surgical procedure whereby tubular coils (stents), which are inserted into the fallopian tubes and cause a blockage against sperm, they are placed using a hysteroscope. A hysteroscope is a thin tube-like camera used to guide the placement of Essure coils. The benefit of this is that it is one and done. Any other temporary measures may lead to unwanted weight gain, abnormal bleeding, headaches, nausea, breast tenderness, and accidental pregnancy due to forgetfulness. All these side effects can be avoided with one simple treatment of Essure.
