Birth control implant

Birth control implant is a type of long-acting reversible contraception (LARC) that is inserted under the skin to prevent pregnancy. It is a small, flexible rod that slowly releases a progestin hormone called etonogestrel into the body over a period of up to three years.

Mechanism of action

The birth control implant works by releasing a steady dose of etonogestrel, which prevents ovulation (the release of an egg from the ovaries). It also thickens the cervical mucus, making it difficult for sperm to reach the egg, and thins the lining of the uterus, which makes it less likely that a fertilized egg will attach and grow.

Effectiveness

The birth control implant is one of the most effective forms of birth control available. It has a failure rate of less than 1%, meaning that less than one in 100 women will get pregnant in a year of using the implant. The effectiveness of the implant does not depend on user action, making it a reliable choice for those who may have difficulty remembering to take a pill every day.

Side effects

Common side effects of the birth control implant include irregular menstrual periods, weight gain, headaches, and mood changes. Some women may also experience pain or bruising at the site of the implant. Serious side effects are rare, but can include infection at the implant site, and in rare cases, the implant can move from its original position.

Insertion and removal

The birth control implant is inserted under the skin of the upper arm by a healthcare provider. The procedure is usually done under local anesthesia and takes only a few minutes. The implant can be removed at any time by a healthcare provider, but must be replaced every three years to maintain its effectiveness.

Advantages and disadvantages

The birth control implant has several advantages, including its high effectiveness, long duration of action, and the fact that it does not require daily action. However, it does not protect against sexually transmitted infections (STIs), and some women may not like the idea of having a device inserted under their skin.
