The results of our study suggest that there is no substantial risk in the first decade after starting use. Whether there are longer-term risks remains unknown, reflecting the fact that this is a relatively recent technology.

There's been at least one study that's shown an increased risk of miscarriage in women who drink moderate amounts of caffeine, and that's only 1 1/2 to 2 cups a day.

For women who have this condition and are at an extremely high risk for two gynecological cancers, this study provides a positive finding.
