Contraceptive vaginal ring

Vaginal rings (also known as intravaginal rings) are 'doughnut-shaped' polymeric drug delivery devices designed to provide controlled release of drugs to the vagina over extended periods of time. For birth control there is Nuvaring - a low-dose contraceptive vaginal ring releasing a progestogen [etonogestrel] and an estrogen [ethinyl estradiol].

The Nuvaring is inserted into the vagina and left in place for three weeks, after which it is removed for a 'ring-free' week to allow menstruation to occur. The ring is held in place by the vaginal walls during the three week period. Nuvaring can remain in place during intercourse. If a couple prefers it can be removed for intercourse, but only for very finite periods of time (an hour, around three hours max to maintain efficacy of birth control properties). Most couples do not report interference or discomfort by leaving Nuvaring in place during intercourse. It is often not even felt.

In rare cases Nuvaring can be expelled from the body without the woman's knowledge; often as a result of constipation. If you think this may be the case it is good to check, but it is rare.

The Nuvaring prescription is similar to birth control pills, requiring an annual pap and physical.
