Planning for pregnancy and delaying pregnancy without health consequences are especially challenging today. Combined hormonal contraceptives are among the most effective methods of preventing unwanted pregnancies, providing high contraceptive reliability, availability and ease of use, safety and reversibility, as well as therapeutic and preventive action in various states. However, according to the State Statistics Committee of Russia, hormonal contraception is used only by 13.4% of women (2009) in this country. This is caused by suspicions both of patients and physicians about side effects of hormonal contraceptives and feasibility of the method in general.
