What Is the Nexplanon Implant?

Nexplanon is a small, flexible rod implanted under the skin of the upper arm that releases a progestin hormone called etonogestrel for up to three years. It is a long-acting, reversible form of contraception, chosen for its low maintenance and high effectiveness.

  • It’s about the size of a matchstick.
  • Its primary function is to stop ovulation and thicken cervical mucus, preventing pregnancy.
  • The procedure for insertion and removal is brief, typically performed in a healthcare provider’s office.
