A new 52-mg levonorgestrel-releasing intrauterine contraceptive system (LNG20) is both safe and effective for nulliparous and parous women for at least 3 years, according to a study of 1,600 women aged 16 to 45 and 36 to 45, including 1,011 nulliparous and 438 obese women. Researchers found:
• Successful placement occurred in 97.9% of participants.
• Six pregnancies occurred, four of which were ectopic.
• Cumulative life-table pregnancy rate was 95% through 3 years.
• Of women who discontinued use and desired pregnancy, 86.8% conceived spontaneously within 12 months.
