Implanon® (implants)

Implanon® is a small plastic rod, about the size of a matchstick, which is inserted just under the skin on the inside of a girl's upper arm. The rod slowly releases a female hormone called progesterone into the bloodstream over a period of three years. But Implanon® won't protect you against sexually transmitted infections (STIs). It's a good idea that both partners have an STI test before having unprotected sex (sex without a condom), even if the girl has Implanon®.

Implanon® works in three ways:

  • Temporarily prevents ovulation (an egg from being released from the ovaries every month).
  • Temporarily thins the lining of the womb (uterus) to prevent a fertilised egg from attaching to it.
  • Thickens the discharge (juices) from the cervix to help prevent sperm from going into the womb (uterus).

When the rod is inserted correctly by a doctor, Implanon® is 99% effective in preventing pregnancy.

Advantages:

  • Convenient - you don't have to remember to take anything.
  • Lasts for a long time - three years.
  • Effective.
  • Easily removed.

Disadvantages:

  • Does not protect against STIs - protection such as condoms must be used.
  • The menstrual cycle is altered, causing irregular periods and spotting through the cycle.

Implanon® costs $5 - $25 every three years plus the cost of insertion by your doctor.

Get it from your doctor or sexual health clinic.

    STIs are infections that can be spread during sexual contact (vaginal, anal, oral sex). Some infections like herpes and warts can also be transmitted by skin to skin contact. Most STIs have no symptoms – so you don’t know you have them.
