ABSTRACT A vaginal spermicide distributing membrane comprises a relatively thin flexible membrane (10) having a plurality of integral rings (12, 14) of thicker dimension on one or both sides thereof. Each ring can have a depression (18) along its surface that functions as a receptacle for spermicide. The rings (12, 14) provide sufficient resistance to deformation so that when the membrane (10) is flexed for insertion in the vagina, it will tend to assume a planar shape and be held in contact with the vaginal mucosa. The rings keep the device properly positioned and function as successive barriers to sperm migration. Loops (22) provided along the periphery of the membrane assist in its insertion and removal.
