Question: 1 / 400

How does the NuvaRing prevent ovulation?

By thickening cervical mucus

By activating directly upon insertion

By releasing synthetic estrogen and progestin

The NuvaRing prevents ovulation primarily by releasing synthetic estrogen and progestin, which work together to inhibit the natural hormonal signals that trigger the release of an egg from the ovaries. The hormones in the ring suppress follicle-stimulating hormone (FSH) and luteinizing hormone (LH), preventing ovulation from occurring.

Additionally, the synthetic hormones contribute to other mechanisms of action, such as thickening the cervical mucus, which makes it more difficult for sperm to enter the uterus. However, the primary method of preventing pregnancy with NuvaRing is through the suppression of ovulation itself.

This understanding of the mechanism is essential because it highlights how hormonal contraceptives function and reinforces the importance of proper usage for effective pregnancy prevention.
