IUD Vs Implant For Birth Control: What’s The Difference?

IUD Vs Implant – In this article, we compare both birth control options on multiple factors like duration, side effects, precautions, safety, etc.

Overview

To protect against pregnancy, you can use either a hormonal implant or an intrauterine device (IUD). Both of these contraception methods are dependable and effective. These are known as LARCs (long-acting reversible contraceptives). Once you get an implant or IUD, you do not have to worry every day to safeguard yourself from unwanted pregnancy. This is because both last for years once they go in. You need a healthcare provider to get an IUD or implant placed or removed.

An IUD and implant are quite effective. They have a success rate of 99% when working correctly. Both these birth control methods do not negatively affect your fertility. After the removal of an IUD or implant, you can get pregnant again.

IUD Vs Implant: Comparision

  • Types of IUDs: An intrauterine device is a soft and tiny T-shaped device. It is placed in the uterus by a doctor. There are 2 types of IUDs: Hormonal and Copper. The hormonal intrauterine device releases progestin in the body. It protects you against pregnancy by stopping the ovaries from releasing eggs, making the cervical mucus thick so that the sperm cannot pass through, and preventing a fertilized egg from implanting on the uterus lining.
  • Birth Control Copper IUD: A Copper IUD is harmful to sperm and disables it. The IUD is wrapped in a thin copper wire. It releases copper ions to destroy sperms so that no pregnancy takes place. The device also disallows a fertilized egg from attaching on the uterus lining.
  • Birth Control Implant: A hormonal implant is the size of a matchstick. It is a tiny tube that the doctor puts under the skin of your upper arm. The implant works to protect you against pregnancy by releasing small amounts of progestin. This makes the cervical mucus too thick for sperm to pass through. It also restricts a release of eggs from the ovaries.

It is rare to encounter any problem with an IUD. However, in rare events, the device may breach the uterus wall. If this happens at the time of placement, then the doctor can rectify it then and there. IUD displaces and not fixed soon, then it may harm the nearby organs, and has to be removed anyhow. If you can feel the strings of IUD in your vagina, it could be a sign of IUD displacement. 

Sometimes the IUD may dislodge partially, and perforate the cervix or uterus. It is possible that you may not even feel anything if the device displaces.

Some of the symptoms to note are:

  • Unusual vaginal discharge or odor
  • Inability to feel the IUD in the cervix

Again, in a rare case, you can conceive while still on an intrauterine device. The pregnancy that occurs can be ectopic, where the fetus develops outside the uterus. You cannot continue such a pregnancy, as it is life-threatening. Such pregnancy will be eliminated by your doctor. Contact your doctor immediately if you feel cramping or sharp pain at the lower abdomen. The pain can be frequent, lasting for more than a few minutes.

A birth control implant can move inside your arm. This may cause the implant to come out. Such an incidence is more common in the first month of getting it. Start using another contraception method immediately if you notice the implant coming out. Also, see a doctor soon so that the implant can be fixed or a new one can be inserted.

If you have an implant, then you need to get it removed after 3 years. Your doctor will take out the implant. If you want to once again use any of these methods, then you can get a new one inserted at your convenience.
