Contraceptive Implants

Contraceptive Implants

Contraceptive Implants are little plastic rods containing hormones. They are inserted under the skin of the arm, slightly above the elbow. The implants release hormones at regular intervals to prevent ovulation and pregnancy. Implanon and Nexplanon are two widely used brands of contraceptive implants.

The hormones that are released by implants prevent pregnancy by:

  • Thinning the uterine lining to stop fertilized egg implantation
  • Thickening the cervical mucus to prevent sperm from entering

Insertion and Removal Techniques

Local anesthetic is injected into the skin of the arm, and using a special needle designed for the implant, the tiny rod is pushed into place. Typically the left arm is used and the designated site is the inner part of the left arm, approximately 4-5 inches above the elbow. Most doctors like to insert the rods in the first five days after a period starts.

Implant removal is done by injecting a local anesthetic and then making a small incision. The implant is then removed through the incision.
