The SILCS diaphragm is a silicone barrier contraceptive device which is inserted vaginally to cover the cervix. The SILCS device was developed by the Program for Appropriate Technology in Health (PATH) and SILCS, Inc. USAID-supported Contraceptive Research and Development Program (CONRAD) supported product development and clinical trials.
It functions identically to a normal contraceptive diaphragm, but avoids the need for many sizes and a pelvic exam for a correct fit; it is designed as a "one size fits most" device.
The designers of the device relied heavily on results from studies of current and former diaphragm users and clinicians to improve acceptability and satisfaction. Women are evaluating the new device for comfort and ease-of-use in studies, underway in the Dominican Republic, South Africa, Thailand, and the United States.
