The levonorgestrel implant (Norplant System; Wyeth-Ayerst Laboratories, Philadelphia, Pa.) is a highly effective and desirable form of contraception for the adolescent population today. Not originally marketed toward this group of young women, it has become a very popular form of birth control for this age group. Even though common side effects are frequently experienced with the use of the Norplant System, timely and reassuring counseling from nurse practitioners is very effective in allaying fears and dissatisfaction. At the Pediatric Clinic for Denton County, Texas, nearly one half of all teenagers enrolled in the Teen Pregnancy Program in 1992 chose the Norplant System as their method of birth control, with very successful results.
左炔诺孕酮植入剂（诺普兰系统；惠氏-艾尔斯特实验室，宾夕法尼亚州费城）是当今青少年群体中一种高效且理想的避孕方式。它最初并非面向这群年轻女性进行销售，但如今已成为这个年龄段非常受欢迎的避孕方式。尽管使用诺普兰系统时经常会出现常见的副作用，但执业护士及时且令人安心的咨询在减轻恐惧和不满方面非常有效。在得克萨斯州丹顿县儿科诊所，1992年参加青少年怀孕项目的所有青少年中，近一半选择诺普兰系统作为他们的避孕方法，且效果非常成功。
