The Contraceptive Implant

9 Jul 2020

What is the contraceptive implant?

The subdermal implant is one of the best long-term contraceptive methods for women.

It is a rod with the size of a match that is placed under the skin on the upper arm.


How does the subdermal implant work?

The implant releases a low dose of a progestational hormone to thicken the mucus in the cervix, which prevents the sperm from swimming to your ovule.

In addition, the implant also usually prevents the ovules from leaving the ovaries (what is known as ovulation); therefore, there are no ovules to fertilize and you cannot get pregnant.

It lasts from 3 to 5 years, however if you decide to get pregnant before, you can remove it.


What side effects can the implant have?

It can happen that some women suffer side effects; the most common is irregular bleeding in the first 6 or 12 months. It may also happen that the implant causes bleeding between periods or these are more abundant and prolonged.

However, in most cases the contraceptive implant makes the menstrual period lighter.

Other side effects that are not usually as frequent can be:

  • Headaches
  • Breast pain
  • Feeling of nausea
  • Weight gain
  • Ovarian cysts
  • Pain, bruising or infection where the implant was placed.



It is important to be clear that the implant does not protect against sexually transmitted diseases (STDs), therefore we advise you to use a barrier method such as a condom.
