NuvaRing is a lightweight and flexible vaginal ring containing 0.015 milligrams (mg) ethinyl estradiol and 0.12 mg etonogestrel per 24 hours. These are derived from progestin and estrogen How the NuvaRing Prevents Pregnancy. The vaginal ring is hormonal birth control that prevents pregnancy by releasing two synthetic sex hormones into the bloodstream, preventing ovulation. The NuvaRing contains two hormones: estrogen (in the form of ethinyl estradiol, 2.7 milligrams (mg)) and progestin (in the form of etonogestrel, 11.7 mg). Introduction. The combined contraceptive vaginal ring (CCVR, NuvaRing ®, Organon Int., Oss, The Netherlands) is a new once-a-month method of hormonal contraception.It consists of a flexible, soft, transparent, ring measuring 54 mm in diameter and 4 mm thickness which can easily be inserted by the woman herself into the vagina (see Fig. 1).After 3 weeks of use the woman removes the ring NuvaRing will not prevent pregnancy if you wear it only during intercourse. You must wear the ring around-the-clock for 3 full weeks (21 days). Do not wear more than one ring at a time. For 7 days after inserting your first vaginal ring, you may need to use back-up birth control (condoms or spermicide, but not a diaphragm or female condom).
