Prior to the insertion of the pellets, the correct individualized dose is calculated by Dr. Rodgers. During the in-office visit, which only takes a few minutes, you’ll be brought into the exam room, and the insertion site is numbed. The most common site of insertion is the upper buttocks. A small incision is then made for pellet insertion. Once the pellet is inserted, the site is covered with a small bandage (no stitches are needed).
