Collagen sponge as vaginal contraceptive barrier: Critical summary of seven years of research

American Journal of Obstetrics and Gynecology, 1985
Extensive testing of collagen sponge as a vaginal contraceptive (mechanical and chemical) showed that the original expectations regarding the safety, convenience, and efficacy were not met. The collagen sponge was tested both as a cylinder and as a diaphragm and used as such or impregnated with spermicidal detergent or with zinc salt.
