Progestins are hormones. The low-dose progestins for contraception are used to prevent pregnancy. Other names for progestin-only oral contraceptives are minipills and progestin-only pills (POPs). Progestins can prevent fertilization by preventing a woman's egg from fully developing. Also, progestins cause changes at the opening of the uterus, such as thickening of the cervical mucus. This makes it hard for the partner's sperm to reach the egg. The fertilization of the woman's egg with her partner's sperm is less likely to occur while she is taking, receiving, or using a progestin, but it can occur. Even so, the progestins make it harder for the fertilized egg to become attached to the walls of the uterus, making it difficult to become pregnant. No contraceptive method is 100 percent effective.Studies show that fewer than 1 of each 100 women become pregnant during the first year of use after correctly receiving the injection on time. Fewer than 10 of each 100 women who take progestins correctly by mouth for contraception become pregnant during the first year of use. Methods that do not work as well include condoms, diaphragms, or spermicides. Discuss with your doctor what your options are for birth control.
