What is the implant and how does it work?
The implant is small soft rod that is placed under the skin of the inner, upper arm.
The implant steadily releases a progestogen hormone into the bloodstream to prevent ovulation. The implant is over 99% effective.
It is fitted under local anaesthetic and no stitches are needed. The area may be tender for a day or two with bruising and some swelling. Most women can feel the implant, but it can't be seen.
