Nuvaring Patches contains Etonogestrel and Ethinyl Estradiol. Etonogestrel and Ethinyl Estradiol both are female hormones. This Ring is available by prescription and prevents the release of an egg from the ovary due to the presence of the two hormones.
Estradiol is a type of estrogen, a female sex hormone produced by the ovaries. It is required for several processes in the body. When it is not produced in sufficient quantities in the body (for example: in postmenopausal women), then it has to be taken in the form of medication.
