Family planning is sometimes used as a synonym or euphemism for access to and the use of contraception. However, it often involves methods and practices in addition to contraception. Family planning is the practice of controlling the number of children in a family and the intervals between their births, particularly by means of artificial contraception or voluntary sterilization. Because "family" is included in the concept's name, consideration of a couple's desire to bear children, in the context of a family unit, is often considered primarily. Contemporary notions of family planning, however, tend to place a woman and her childbearing decisions at the center of the discussion, as notions of women's empowerment and reproductive autonomy have gained traction in many parts of the world. Family planning may involve consideration of the number of children a woman wishes to have, including the choice to have no children, as well as the age at which she wishes to have them. These matters are obviously influenced by external factors such as marital situation, career considerations, financial position, and any disabilities that may affect their ability to have children and raise them, besides many other considerations. If sexually active, family planning may involve the use of contraception and other techniques to control the timing of reproduction.
