Contraceptive Implant

The contraceptive implant is a type of long-acting reversible contraception (LARC) that is inserted under the skin to prevent pregnancy.

How it Works

The contraceptive implant releases a small amount of progestin, a hormone that prevents ovulation, into the bloodstream. This hormone also thickens cervical mucus, making it difficult for sperm to reach the egg, and thins the lining of the uterus, preventing a fertilized egg from implanting.

Types of Contraceptive Implants

There are several types of contraceptive implants available, including:

• Nexplanon (etonogestrel implant): This is a single rod implant that releases etonogestrel, a type of progestin.
• Implanon (etonogestrel implant): This is also a single rod implant that releases etonogestrel, similar to Nexplanon.
• Norplant (levonorgestrel implant): This is a six-rod implant that releases levonorgestrel, another type of progestin.

Insertion and Removal

The contraceptive implant is inserted under the skin of the upper arm by a healthcare provider. The procedure typically takes about 10-15 minutes and can be done in a doctor's office. The implant can be removed at any time, but it must be done by a trained healthcare provider.

Effectiveness

The contraceptive implant is over 99% effective in preventing pregnancy when inserted correctly. It is also effective for up to three years, although some implants may last longer.

Benefits

The benefits of the contraceptive implant include:

• High effectiveness in preventing pregnancy
• Long-acting, so no need to remember to take a pill every day
• Reversible, so fertility returns quickly after removal
• Can reduce menstrual cramps and heavy bleeding
