Barrier and Other Pericoital Contraceptives
pH regulator contraceptive gel
Contraceptive pH regulator vaginal gel changes the vaginal pH; this change incapacitates sperm and thus prevents fertilization. The gel contains primarily lactic and citric acids. The pregnancy rate is 7% with perfect use and 14% with typical use. Using other barrier methods with vaginal gel improves efficacy. pH regulator vaginal gel should be placed in the vagina no more than 1 hour before sexual intercourse and reapplied before each episode of sexual intercourse. It does not reliably protect against STIs.
