Implants For Birth Control
Implants are small rods that are surgically inserted just under the skin of a woman's upper arm. Each rod slowly releases a progestin hormone into the surrounding tissues where it enters the bloodstream. Progestin is a hormone that prevents pregnancy by preventing ovulation and thickening cervical mucus.
Implanon and Nexplanon are new implants now available in the United States. They consists of a single rod that is implanted under the skin of the upper inner arm and slowly releases low levels of progestin. The rod provides birth control protection for three years but can be removed sooner.
Implanon and Nexplanon are as effective as sterilization in preventing pregnancy but it is reversible. The implant is easy to monitor because the rods can be felt on the inner side of your upper arm. Once positioned under the skin, there is little concern about the device malfunctioning.
