The formation of adolescent reproductive health is the main trigger of demographic growth. This process is based on knowledge about the need to preserve reproductive health, its relationship with somatic and mental health, risk factors and the basics of prevention of disorders. The Russian system of reproductive health protection of children and adolescents is much more effective than similar systems in foreign countries. It includes a more advanced mechanism of preventive examinations, built on respect for the traditional values of the family as a union of men and women, care for the younger generation, sexual integrity of minors. The paper shows the specific achievements of the pediatric and adolescent gynecology service of the Tyumen region: solving the personnel problem, reducing the gynecological morbidity of minors, reducing the frequency of pregnancies and its termination in girls under the age of 18. These achievements are based on consistent work on teaching the basics of hygiene, on the formation of health-preserving reproductive behavior and safe reproductive behavior in minors: schoolchildren, students of secondary specialized educational institutions. At the same time, reproductive losses, which compete with childbirth in their frequency, are a serious obstacle to solving urgent demographic problems. The authors see the solution to the problem in the formation of a cult of a healthy lifestyle among adolescents, creation of effective conditions for the timely detection and treatment of gynecological diseases in minors.
