Oral contraceptive pills. These combined pills contain the hormones oestrogen and progesterone, which suppress ovulation. An increase in the thickness of the mucus in the cervix (neck) of the uterus occurs, as well as an altering of the lining of the uterus. Both these changes reduce the likelihood of fertilisation or implantation of a fertilised egg, should fertilisation occur.
