Purpose
This is a pilot study to determine the feasibility for a randomized controlled trial of two forms of intrauterine contraception: the Levonorgestrel intrauterine system (LNG-IUS) and the Copper T 380A.

Primary Outcome Measures:
- Retention Rate [ Time Frame: 6 months ]Percentage of participants who completed the final visit (i.e., not subject to early termination or loss to follow-up)
Secondary Outcome Measures:
- Heavy Bleeding Rates [ Time Frame: 6 months ]Rates of participants experiencing heavy bleeding among teens randomized to the LNG-IUS or Copper T 380A.
- Pregnancy Rates [ Time Frame: 6 months ]Proportion of subjects who became pregnant within 6 months of IUD insertion
- Expulsion Rates [ Time Frame: 6 months ]Rates of partial or complete expulsion for teens randomized to the LNG-IUS or Copper T 380A. Patients experiencing partial expulsion had IUDs visible on speculum exam. Complete expulsion is characterized by complete evacuation of the IUD.
- Device Satisfaction Rates [ Time Frame: 6 months ]Satisfaction rate is the proportion of subjects who report being "happy" or "very happy" with their assigned intrauterine contraceptive method on the date of their 6 month study visit.

| Arms | Assigned Interventions |
|---|---|
|
Active Comparator: Mirena IUD [LNG-IUS]
Participants in this arm had a Levonorgestrel-releasing intrauterine device (LNG-IUS), also known as the Mirena IUD, inserted within the first 5 days of the adolescent's menstrual cycle, at least 7 weeks after a vaginal or cesarean delivery or second-trimester abortion or at least 3 weeks after a first-trimester abortion. For participants who had used depot-medroxyprogesterone acetate, insertions occurred at least 6 months after the participant's last injection. Participants were blinded to the device type; however, investigators and research assistants were not.

Device: Levonorgestrel-releasing intrauterine device (LNG-IUS)
Teens are randomly assigned to receive the LNG-IUS after completing a screening visit.
Other Name: Mirena IUD

Active Comparator: Paragard IUD [Copper T380A]
Participants in this arm had a Copper T380A intrauterine device (CuT380A), also known as the Paragard IUD, inserted within the first 5 days of the adolescent's menstrual cycle, at least 7 weeks after a vaginal or cesarean delivery or second-trimester abortion or at least 3 weeks after a first-trimester abortion. For participants who had used depot-medroxyprogesterone acetate, insertions occurred at least 6 months after the participant's last injection. Participants were blinded to the device type; however, investigators and research assistants were not.

Detailed Description:
Teenagers have the highest percentage of unintended pregnancies, and often struggle to comply with daily methods of contraception. The intrauterine device (IUD) provides safe, long-term protection and rates highly for patient satisfaction. It also does not require repeat prescriptions or clinic visits, making it a potentially attractive method among teens. However, in adolescent populations, there is both a lack of information about the IUD, as well as few studies that have examined the use of these devices. This study will examine whether a larger scale study on this topic is feasible. IT will address the feasibility of recruiting, consenting, screening, enrolling, randomizing, and retaining adolescents randomized to the LNG-IUS or Copper T 380a.
