Can a 13‑year‑old female safely use an intrauterine device (IUD) and what are the eligibility criteria and considerations?

IUD Use in 13-Year-Old Adolescents

Yes, a 13-year-old can safely use an IUD—both copper and levonorgestrel IUDs are appropriate contraceptive options for adolescents of any age after menarche, with no age-based contraindications. 1, 2

Eligibility and Safety Classification

According to the 2024 CDC U.S. Medical Eligibility Criteria, IUDs receive a Category 2 classification for adolescents from menarche to age 20, meaning the advantages generally outweigh theoretical or proven risks. 1 This classification applies to both:

• Copper IUD (Cu-IUD): Category 2 for ages menarche to <20 years 1
• Levonorgestrel IUD (LNG-IUD): Category 2 for ages menarche to <20 years 1

The American Academy of Pediatrics explicitly states that IUDs are safe for nulliparous adolescents and should be presented as first-line contraceptive options alongside implants when counseling about long-acting reversible contraception (LARC). 2

Key Safety Evidence

Insertion Success Rates

Real-world data demonstrates excellent feasibility in young adolescents:

• 96.2% first-attempt success rate in adolescents aged 13-24 years 3
• 95.5% success rate specifically in 13-17 year olds compared to 96.3% in 18-24 year olds (no significant difference) 3
• 95.8% success in nulliparous adolescents versus 96.7% in parous adolescents (no significant difference) 3
• Advanced practice clinicians successfully placed 86% of IUDs, demonstrating this is not limited to physician-only procedures 3

Infection Risk

The historical concern about pelvic inflammatory disease (PID) in adolescents has been definitively refuted:

• Infection risk occurs only during the first 21 days after insertion; IUDs do not increase STI or PID rates beyond this period 2
• IUDs do not cause tubal infertility in nulliparous women 2
• STI screening (gonorrhea and chlamydia) can be performed on the day of insertion unless the patient is at very high risk 2
• If STIs are diagnosed post-insertion, treatment can be provided with the IUD in place—removal is not required 2

Absolute Contraindications

The only true contraindications to IUD placement are: 2

• Current purulent cervicitis
• Active gonorrhea or chlamydia infection
• Current pelvic inflammatory disease
• Other active pelvic infections

Important caveats:

• Past history of PID is NOT a contraindication 2
• HIV infection is NOT a contraindication 2
• Immunosuppression is NOT a contraindication 2
• Nulliparity is NOT a contraindication 2
• Young age (<18 years) is NOT a contraindication 1, 3

Practical Considerations for Young Adolescents

Expected Outcomes

• Continuation rates in adolescents exceed those of other hormonal methods, making IUDs particularly valuable for preventing unintended pregnancy in this high-risk population 2
• 50% of adolescents <18 years had their IUD in place at 5 years, compared to 71.5% in 18-21 year olds 4
• Adolescents under 18 have higher removal rates (hazard ratio 2.85) but still maintain better continuation than short-acting methods 4

Potential Complications

• Expulsion rates: Occur in fewer than 5% overall, may be slightly higher in younger women, but age was not a statistically significant risk factor in most studies 2, 4
• Pain with insertion: More than half of young nulliparous women report moderate to severe pain during insertion 2
• No perforations were identified in the first 6 months in a large adolescent cohort 3
• Only 1.8% of successful insertions required ancillary measures (paracervical block, cervical dilation) 3

Clinical Approach

When offering IUDs to 13-year-olds:

• Counsel about pain management options before insertion, as nulliparous adolescents experience more discomfort 2, 5
• Screen for STIs on insertion day unless very high risk (e.g., partner with known gonorrhea) 2
• Counsel about irregular bleeding, particularly with LNG-IUD, as adolescents are less tolerant of bleeding side effects than adults 6
• Emphasize that IUDs do not protect against STIs—consistent condom use remains essential 1, 2
• Consider the 13.5 mg levonorgestrel IUD (Skyla) as it was specifically designed with a smaller inserter, though standard IUDs are also appropriate 2

Device Options

Three IUDs are FDA-approved and appropriate for adolescents: 2

• 52 mg levonorgestrel IUD (Mirena): 5-year duration
• 13.5 mg levonorgestrel IUD (Skyla): 3-year duration
• Copper T380-A (ParaGard): 10-year duration, also serves as emergency contraception if placed within 5 days of unprotected intercourse 2

The inability to provide ancillary measures such as paracervical block or cervical dilation should not limit access to IUDs in adolescents, as these are rarely needed. 3
