Birth control is a term that includes all methods used to regulate or prevent the birth of children. Other terms with a similar meaning are birth planning, family planning, fertility control, and planned parenthood.
When people talk about birth control, they are usually referring to artificial methods. But nature itself has built-in controls for limiting and spacing births. A woman can become pregnant only during a small fraction of her monthly menstrual cycle. In addition, women are able to conceive only during a certain time in their lives
