The levonorgestrel intrauterine system (LNG-IUS) is an underused contraceptive method in adolescent populations. In addition to being a highly effective, reversible, long-acting contraception, the LNG-IUS has many noncontraceptive health benefits including reduced menstrual bleeding, decreased dysmenorrhea and pelvic pain related to endometriosis, and menstruation suppression in teens with physical or developmental disabilities. The LNG-IUS can also provide endometrial protection in teens with chronic anovulation, and may be used to treat endometrial hyperplasia and cancer. This review examines the evidence supporting the use of the LNG-IUS in adolescents for these noncontraceptive benefits.
左炔诺孕酮宫内节育系统（LNG-IUS）在青少年人群中的使用并不广泛。除了作为一种高效、可逆、长效的避孕方法外，LNG-IUS 还具有许多非避孕健康益处，包括减少月经出血、减轻与子宫内膜异位症相关的痛经和盆腔疼痛，以及抑制身体或发育障碍的青少年的月经。LNG-IUS 还可以为患有慢性无排卵的青少年提供子宫内膜保护，也可用于治疗子宫内膜增生和癌症。本文综述了支持 LNG-IUS 在青少年中用于这些非避孕益处的证据。
