The primary function of the NuvaRing is to prevent pregnancy. It is a form of hormonal contraception classified as a combined contraceptive method, delivering a steady supply of hormones—specifically estrogen and progestin—through the vaginal mucosa. These hormones work together to inhibit ovulation, ensuring that the ovaries do not release an egg. Additionally, the hormones thicken the cervical mucus, making it more difficult for sperm to enter the uterus, and alter the uterine lining to reduce the likelihood of implantation should fertilization occur.

While the NuvaRing may have secondary benefits such as potentially decreasing menstrual flow and alleviating symptoms related to hormonal imbalances, its primary and most critical role is to act as a contraceptive method to prevent pregnancy. Other options listed, such as regulating hormonal balance or alleviating symptoms of menopause, do not reflect its main purpose as a contraception device specifically designed for this function.
