Abstract
This fact sheet provides information about how the progesterone vaginal contraceptive ring works to prevent pregnancy. The progesterone vaginal ring (PVR) offers a novel way of delivering safe and effective contraceptives for lactating women. When used by such women it prevents pregnancy by inhibiting follicular growth, hence preventing ovulation; reinforcing the inhibitory effect of breastfeeding on ovulation; extending postpartum amenorrhea; and thickening the cervical mucus, thus inhibiting sperm from meeting the egg. The PVR expands the range of contraceptives available to lactating women and has the potential to contribute to improving maternal and infant health.
