Introduction
Choosing the right birth control can feel overwhelming. With so many options available, it’s easy to get confused — especially when comparing two of the most effective methods available today: IUD vs Nexplanon. Both are long-acting, highly reliable, and low-maintenance, which makes them popular choices for people who want stress-free contraception.
However, many people mix them up because they’re both implanted by a healthcare provider and last for years. Some even assume they work the same way — but that’s not true.
Although they look/sound similar, they serve completely different purposes.
Understanding the real differences between IUD vs Nexplanon can help you make a confident, informed decision about your reproductive health. This guide breaks everything down in simple language — how each works, how they differ, and which one might suit your lifestyle best.
What Is an IUD?
An IUD (Intrauterine Device) is a small, T-shaped device placed inside the uterus by a healthcare professional to prevent pregnancy.
Meaning & How It Works
An IUD works by:
- Preventing sperm from reaching an egg
- Changing the uterine environment to stop fertilization
- In some cases, thinning the uterine lining
There are two main types of IUDs:
- Hormonal IUDs (Mirena, Kyleena, Liletta)
- Copper IUD (Paragard)
Where It’s Used
IUDs are widely used worldwide and are recommended by doctors as one of the most effective forms of reversible birth control.
In the IUD vs Nexplanon comparison, IUDs are often preferred by people who want options with or without hormones.
Examples in Sentences
- She chose an IUD because it lasts several years.
- A copper IUD doesn’t contain hormones.
- Many doctors recommend an IUD for long-term birth control.
Historical Note
IUDs have been used since the 1960s and have evolved significantly to become safer, smaller, and more comfortable. Today, they are among the most trusted contraceptive methods globally.
What Is Nexplanon?
Nexplanon is a small, flexible hormonal implant placed under the skin of the upper arm to prevent pregnancy.
Meaning & How It Works
Nexplanon releases progestin, a hormone that:
- Stops ovulation
- Thickens cervical mucus to block sperm
- Thins the uterine lining
Unlike an IUD, Nexplanon works entirely through hormones.
Where It’s Used
Nexplanon is widely used in the USA and many other countries as a long-acting contraceptive option.
In the IUD vs Nexplanon discussion, Nexplanon is often chosen by people who prefer not to have a device placed in the uterus.
Examples in Sentences
- She got Nexplanon for worry-free birth control.
- Nexplanon is effective for up to three years.
- The implant is placed just under the skin.
Usage Note
Nexplanon replaced an older implant called Implanon and is currently considered over 99% effective, making it one of the most reliable birth control methods available.
Key Differences Between IUD and Nexplanon
Quick Differences (Bullet Points)
- Placement: IUD goes in the uterus; Nexplanon goes in the arm
- Hormones: IUD can be hormonal or non-hormonal; Nexplanon is hormonal only
- Duration: IUD lasts 3–10 years; Nexplanon lasts up to 3 years
- Periods: IUD may reduce or increase bleeding; Nexplanon often causes irregular periods
- Removal: Both require a healthcare provider
