Potential Delivery of Contraceptive Agents to the Female Reproductive Tract
Vaginal contraceptives have played a positive role in fertility planning for years. Prior to the introduction of intrauterine devices (IUDs) and oral contraceptives (OCs), jellies, creams, and suppositories were used, sometimes in conjunction with the diaphragm or condom, but usually they served as the sole barrier.1 The higher failure rates of the vaginal contraceptives in relation to other contraceptive devices (IUDs and OCs) were believed to be due primarily to the inconsistent use of the method rather than to failure of the method during use.
