|---|---|---|
| **Mechanism** | Releases copper ions to disable sperm | Releases low-dose progestin to thicken cervical mucus |
| **Duration** | 5 to 10 years | 3 to 8 years (depending on brand/model) |
| **Hormone Content** | 100% hormone-free | Localized progestin (levonorgestrel) |
| **Menstrual Effect** | May cause heavier periods or cramping initially | Typically reduces flow, cramps, or stops menstruation |
| **Best For** | Women avoiding synthetic hormones | Women managing heavy periods or endometriosis |

## Q&A

**Q: What is an IUD (Alat Perancang Dalam Rahim)?**
A: An IUD is a small, T-shaped contraceptive device placed inside the uterus by a medical professional. It is over 99% effective and offers reversible, long-term protection against pregnancy without requiring daily action.

**Q: What is the main difference between copper and hormonal IUDs?**
A: Copper IUDs prevent sperm motility without hormones and last up to 10 years, though they may temporarily increase menstrual flow. Hormonal IUDs release localized progestin, last 3–8 years, and often lighten menstrual cycles.

**Q: Who is a suitable candidate for an IUD?**
A: Most healthy adult women seeking multi-year contraception are suitable candidates, including those who have or have not given birth. A pelvic examination and medical assessment are essential prior to insertion.

**Q: What are the common side effects and risks associated with IUDs?**
A: Common side effects include mild pelvic cramping and irregular spotting during the first 3–6 months. Rare risks include device displacement, expulsion, or pelvic infection. Consult a physician immediately if severe pain or high fever occurs.

**Q: How does Dr.Ann support feminine and intimate health in Malaysia?**
A: Dr.Ann provides research-backed educational content and lab-tested feminine care products tailored for the tropical Malaysian climate, helping women maintain balanced microflora and optimal intimate hygiene.
