An intracervical device for the controlled release of an active agent for the prevention of both specific sexually transmitted diseases and pregnancy. The device consists of an entirely erodible polymer, or a combination of an erodible polymer with a skeletal polymer capable of maintaining therefor mechanical properties over long duration in the body. The active agents can include one or more than one of a large family of insoluble metal salts which have been shown to affect sperm motility and/or viability and are effacious in the prevention of sexually transmitted diseases. These agents are slowly released over a defined period of time ranging from one month to up to 18 months in duration due to erosion of the polymer matrix.
