NuvaRing is a small plastic contraceptive device shaped like a ring that is prescribed to prevent unplanned pregnancy. The device contains synthetic estrogen (ethinyl estradiol) and progestin (etonogestrel). These hormones prevent the release of an egg during ovulation. They also change the cervical mucus and the uterine wall to keep sperm from fertilizing an egg. Combined, these measures vastly reduce the likelihood that you’ll get pregnant.
NuvaRing is only available via prescription from a licensed healthcare provider.
