Menstrual Disorders in Adolescence: Diagnostic and Therapeutic Challenges.

: Adolescence is the period of life between the ages of 10 and 19. This period is essentially dominated by puberty. The first menstruation, called menarche, occurs, on average, at the age of 12-13. The period after menarche, especially the first 2 years, is characterized by anovulatory cycles, which can be accompanied by menstrual irregularities. This review aims to describe the current status of the diagnostic and therapeutic challenges of the physiological and pathological causes of menstrual irregularities in adolescence and evaluates the benefits from interdisciplinary collaboration to ensure optimal care. : A systematic literature search was conducted in the PubMed database in April 2024 using the following term: "menstrual disorder adolescence". A total of 1724 abstracts were screened, and relevant articles from the last 10 years were included. In addition, a supplementary topic-relevant literature search of the guidelines of the European Society of Human Reproduction and Embryology (ESHRE) and the guidelines of the Arbeitsgemeinschaft der wissenschaftlichen medizinischen Fachgesellschaft (awmf) was carried out. In addition to cycle irregularities that occur physiologically as a result of anovulatory cycles in the context of the immaturity of the hypothalamic-pituitary-gonadal axis, there are other cycle abnormalities that can be classified as pathological and need to be recognized and treated. : Increasing awareness of the various specialist disciplines of physiological and pathological cycle abnormalities in adolescence and interdisciplinary cooperation between them can have a positive influence on the quality of life of adolescent women with cycle abnormalities.
