The contraceptive implant, known as Nexplanon in the UK, is a small yet powerful tool for birth control. This flexible rod, about 4cm long, is inserted under the skin of your upper arm and works wonders by releasing a synthetic hormone called etonogestrel into your bloodstream. It’s designed to prevent pregnancy effectively for up to three years.
You might be wondering how it all works. The implant primarily stops ovulation—meaning no eggs are released from your ovaries each month. Additionally, it thickens cervical mucus, making it harder for sperm to reach an egg if one were released. And if that weren’t enough, it also thins the lining of the womb so that even if fertilization occurs, implantation becomes difficult.
What makes Nexplanon particularly appealing is its convenience; once it's in place by a trained healthcare professional (like a doctor or nurse), you can forget about daily pills or weekly patches. Just set it and forget it! However, remember that while this method boasts over 99% effectiveness when used correctly, you'll need to replace it after three years for continued protection.
Insertion involves lying back with your arm bent at the elbow—a simple procedure where local anesthetic ensures comfort during placement. Afterward, you’ll receive a Patient Alert Card detailing when you had it placed and when it's due for replacement.
If you're considering starting or switching methods of contraception but have concerns about hormonal side effects like changes in periods or weight gain—common experiences among users—it’s always best to discuss these with your healthcare provider beforehand.
In summary: Nexplanon lasts three years before needing replacement—but rest assured that once removed, fertility returns quickly! So whether you're looking at family planning options now or down the line, you'll know exactly what role this little device can play.
