What is the minimum age recommended for the insertion of a Mirena IUD?

1. 18 years

2. 20 years

3. 25 years

4. 30 years

The correct answer is: 20 years

The recommendation for the minimum age for Mirena IUD insertion is typically guided by professional guidelines which suggest that it can generally be inserted in individuals who are 18 years or older. The Mirena IUD is an intrauterine device that releases levonorgestrel, a hormone effective for contraception and management of heavy menstrual bleeding. Its use is usually advised for those who have a history of childbearing, but it is also deemed safe for nulliparous women of reproductive age starting at 18. Choosing an age of 20 years might stem from caution around the physical and emotional maturity needed to manage an IUD, or potential complications that may arise in younger candidates. However, medical guidelines generally allow for insertion at 18, making the age of 20 an unnecessarily restrictive recommendation in practice. In clinical settings, the decision for IUD insertion is personalized, factoring in individual health, fertility plans, and consent.
