An investigational vaginal contraceptive ring that elutes ferrous gluconate, ascorbic acid and glycine keeps vaginal pH at a relatively stable acid environment, averaging 4.5, and the ferrous gluconate binds with sperm, blocking sperm motility almost completely, according to new research presented here at the annual meeting of the American College of Obstetricians and Gynecologists.
