Abstract Introduction. Sexology is defi ned as the scientifi c study of human sexuality, including its development, behaviour, functions and preferences. A lot of gynaecological problems are linked to sexual development. Development of the sexual organs is strictly associated with the function of the hypothalamic-pituitary-adrenal axis. Conclusion. The aim of the study was to emphasize the importance of nursing care in sexual education on the example of masturbation of children. Paediatric and adolescent gynaecology is a multidisciplinary fi eld. Gynaecological problems among children and adolescents are often complex, both in terms of medicine and psychology, and require an interdisciplinary approach, including nursing care.
