Implanon ® (subdermal implant/rod/bar)
99.95% effective
The implant is about the size and shape of a matchstick. It is inserted under the skin of the upper arm. The doctor will give local anaesthetic injection to numb the area first. It contains the hormone progestogen, which stops the ovary from releasing an egg and thickens the cervical mucus so sperm cannot get through.
