Family planning services are necessary for the widespread adoption of preconception care for two reasons. First, preconception care is more likely if pregnancies are planned, and family planning services encourage pregnancy planning.

However, the potential of family planning services to promote preconception care is limited by underutilization of these services and inadequate attention to preconception care during family planning visits. This article suggests ways to reduce these problems.
