title: The acceptance of the collagen sponge diaphragm as an intravaginal contraceptive in human volunteers.
abstract: Two types of highly resilient and liquid-absorbent collagen sponge contraceptives (CSC) in the shape of cylindrical cups (6 cm wide and 2.5 cm thick) were evaluated for acceptance as an intravaginal contraceptive method for a period of 3 months in 27 volunteers. Parameters such as retention, odor, irritation, itching, discharge, and convenience for the user and her sexual partner were tested. Average retention time was 7 to 9 days (range, 2 to 28 days); still, most sexually active volunteers preferred to remove the CSC every 3 to 4 days, rinse them in tap water, and reinsert them. Odor was noticed by users in 4% of the tested sponges and in 30% of all volunteers by medical personnel at the time of removal of the CSC from the vagina. No irritation, itching, or discharge was reported. The CSC alone did not cause any inconvenience to the user or partner, while the CSC with inserted rubber ring was felt by both partners and was found to be dislocated. This study indicates good acceptance of the CSC in intravaginal use. Studies to evaluate the efficacy of collagen sponges as mechanical contraceptive barriers are in progress.
