Medical Conditions - Contraceptive Implant

A contraceptive implant is a small and flexible rod that is implanted under the skin of a woman's upper arm. It releases a hormone called progestin, which prevents pregnancy by thickening cervical mucus, inhibiting ovulation, and thinning the lining of the uterus. The implant can last up to three years and is highly effective, with a failure rate of less than 1%. It is a convenient and discreet form of birth control, but may have some side effects such as irregular bleeding, weight gain, or mood changes.
