2. Cooper T –
The Cooper T is an effective method and has been used by women’s since 5 decades, and it is 99 % effective. But you need a doctor to implant it. The Copper T is a simple intra-uterine device (IUD) made of a flexible, “T” shaped piece of plastic wrapped with a thin copper containing wire. This shape is chosen as it fits the area around the uterus, allowing for the Copper T to sit in place for years without moving around.When inserted, the ends of the “T” are folded and inserted into the patient with a straw-like tube. Once in place, the spermicidal effects of the Copper T are in effect, and the tiny piece of plastic and copper becomes a birth control device.
Copper ions prevent pregnancy by inhibiting the movement of sperm because the copper-ion-containing fluids are directly toxic to sperm.
