Contraception in Canada: a review of method choices, characteristics, adherence and approaches to counselling.

Contraception is a significant concern for Canadian women of child-bearing age, their partners and their health care providers. In this narrative review we provide information on current trends and recent changes in Canadians' choices of contraceptive methods. We review the characteristics of contraceptive methods available in Canada, with an emphasis on hormonal methods and newer options such as the transdermal contraceptive patch, the vaginal contraceptive ring and the levonorgestrel-releasing intrauterine system. We also discuss adherence to contraception as well as approaches to counselling to promote adherence and to reduce the risk of sexually transmitted infections in the context of contraception.
