The contraceptive vaginal ring is a novel contraceptive method that offers unique advantages. Intravaginal delivery of both estrogen and progesterone allows continuous release of medication, resulting in lower systemic levels. The use of long-term combined hormonal contraception enables improved cycle control compared with progesterone-only methods. The indications and usage of the NuvaRing(®) are described along with the efficacy, tolerability, and safety. Overall, the contraceptive vaginal ring appears to be very effective, with a favorable side-effect profile, and is highly acceptable to most patients.
避孕阴道环是一种新型的避孕方法，具有独特的优势。阴道内同时输送雌激素和孕激素可以持续释放药物，从而降低全身水平。与仅孕激素方法相比，长期使用复方激素避孕药可以更好地控制周期。本文介绍了 NuvaRing（®）的适应证和用法，以及其疗效、耐受性和安全性。总的来说，避孕阴道环似乎非常有效，副作用小，大多数患者都能接受。
