Birth control that's in your skin? i heard of 2 methods thats are put in your skin what are they called and are they expencive?

There : There are two forms of birth control that are given by injection. One uses an implantable rod, which is a matchstick-size, flexible rod that is put under the skin of the upper arm. It is often called by its brand name, implanon. The rod releases a progestin, which causes changes in the lining of the uterus and the cervical mucus to keep the sperm from joining an egg. Less often, it stops the ovaries from releasing eggs. It is effective for up to 3 years. The cost of the exam, implanon, and insertion ranges from $400—$800 the other is a birth control shot often is called by its brand name depo-provera. With this method you get injections, or shots, of the hormone progestin in the buttocks or arm every 3 months. There is a new type is injected under the skin. The birth control shot stops the ovaries from releasing an egg in most women. It also causes changes in the cervix that keep the sperm from joining with the egg. The shot should not be used more than 2 years in a row because it can cause a temporary loss of bone density. The loss increases the longer this method is used. The bone does start to grow after this method is stopped. But it may increase the risk of fracture and osteoporosis if used for a long time. Office visits to obtain your prescription and the birth control injections range from $50 to $200; follow up visits for additional injections are usually between $20 to $40. The cost for your quarterly injection ranges between $30 and $75.
