The vaginal contraceptive ring works systemically by releasing 120 micrograms etonogestrel (a third generation progestogen) and 15 micrograms ethinylestradiol per day. As little independent research has been done on the efficacy and effectiveness of the vaginal contraceptive ring, it seems too early for the uncompromising propagation of systemic vaginal contraception. Women who occasionally omit to take the pill and those reluctant to use an intra-uterine device may possibly benefit from this form of contraception.
