Today, diabetic women have an increasing variety of safer and effective contraceptive methods. While more contraceptive trials in diabetic women are needed, data from existing studies and extrapolation from clinical trials in healthy women support the use of most contraceptive methods. This chapter will review contraception in women with type 1 (DM1) and type 2 (DM2) diabetes mellitus, with or without sequelae. It will also review contraception in prediabetic women, e.g., with previous gestational diabetes mellitus to augment the limited studies in women with DM2. The goal will be to provide a simple question-based approach to individualized counseling, considering diabetic sequelae and comorbidities, metabolic effects, and lifestyle demands.
