The vaginal ring (brandname: NuvaRing) is a form of birth control for women that is inserted internally for three weeks and then removed for the week of menstruation. It is a flexible (non-latex) ring that is discreet, usually undetectable to the wearer, and allows intercourse to be more spontaneous.
NuvaRing works much like regular birth control pills by releasing estrogen and progestin into the bloodstream. Much like the Pill or a birth control patch, the vaginal ring prevents ovulation (an ovary releasing a monthly egg.) The endometrial lining usually thickens to accept a fertilized egg, but the NuvaRing prohibits such an optimal endometrium. Cervical mucus also thickens to prevent sperm from entering the uterus.
NuvaRing Use and Effectiveness
The NuvaRing is inserted into the vagina and the muscles in the vaginal wall keep it in place. It is generally not felt when properly inserted. It cannot get lost because the cervix prevents it from getting into the uterus. The vaginal ring is usually not felt during exercise or intercourse.
When used correctly, the NuvaRing is as effective as a birth control patch (99%.) This is slightly more effective than the Pill. Check with a health professional as to proper use and removal.
NuvaRing Side-Effects
Like other forms of birth control that contain hormones, there are side-effects to consider when using the vaginal ring. They include:
- possible weight gain, nausea, vomiting, and/or breast tenderness
- moodiness
- spotting between periods
- possible increased susceptibility to vaginal infections
- headaches
- increased menstrual cramping (rare)
More serious side-effects are less common. They can include:
- an increased risk for developing blood clots in the legs, heart, lungs, or brain
- an increased risk for having a stroke or heart attack
- an increased risk for developing breast cancer
Check with a doctor for the actual percentage of risk. Some serious risks are increased if a patient is over 35 and smokes.
NuvaRing Benefits
The vaginal ring can benefit a patient in various ways:
- once-a-month birth control (unlike a daily pill)
- like a birth control patch, hormones are continuously and evenly absorbed into the bloodstream, keeping side-effects to a minimum
- shorter, lighter periods (decreased risk for developing anemia)
- decreased premenstrual symptoms (usually)
- ovulation quickly returns after stopping the vaginal ring
- decreased risk for developing ovarian cysts
- decreased risk for developing ovarian or endometrial cancer
It's important to discuss the benefits v. the side-effects of the NuvaRing with your doctor. Not every patient is a good candidate for the vaginal ring. Together, you and your doctor can determine your best choice for birth control.
