Lo/Ovral is categorized as a combined oral contraceptive, the most common type of birth control pill. Combined oral contraceptives contain a combination of two different types of hormones: an estrogen and a progestin. The hormones in Lo/Ovral prevent pregnancy primarily by stopping ovulation (the maturation and release of eggs from the ovaries).
Lo/Ovral also works to prevent pregnancy in two other, less important ways. It alters the lining of the uterus (the endometrium), making it less receptive to an embryo. It also changes the cervical mucus (the fluid of the cervix, which is the lower, narrow part of the uterus that is connected to the vagina), making it more difficult for sperm to enter the uterus.
