The short explanation
Both are small T-shaped devices placed in the womb, and both are very effective at preventing pregnancy for several years. The difference is in how they work. A Copper T releases copper and contains no hormones; it can make periods heavier. A hormonal IUD releases a small amount of a progestogen hormone directly into the womb, which thins the lining and usually makes periods much lighter and less painful. Some women stop having periods altogether. This is why a hormonal IUD is often suggested for women with heavy periods who also want contraception. Because the hormone acts mainly in the womb, side effects elsewhere in the body are usually mild, though some women notice spotting in the first months, breast tenderness, acne or mood changes.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Irregular spotting is common for the first three to six months and usually settles.
- A hormonal IUD may cost more than a Copper T; availability in government hospitals varies.
- It can also be used to protect the womb lining with some types of menopause treatment.
