| Birth control - slow release methods : Certain birth control methods contain man-made forms of hormones. The natural forms of these hormones are normally made in a woman's ovaries. These hormones are called estrogen and progestin. Both of these hormones prevent a woman's ovaries from releasing an egg. The release of an egg during the menstrual cycle is called ovulation. They do this by changing the levels of the natural hormones the body makes. Progestin also helps prevent sperm from entering the uterus by making the mucous around a woman's cervix thick and sticky. Birth control pills are one way of receiving these hormones. They are only effective if taken daily, preferably at about the same time. There are other methods to prevent pregnancy. The same hormones may be used but they are released slowly over time. | |
