Physiological role and diagnostic value of anti-Mullerian hormone in pediatrics
Abstract
Background. Anti-Mullerian hormone (AMH) has now gained popularity as a marker of ovarian reserve. It is important to determine the place and role of AMH in children. The purpose of this work was to analyze the data of the scientific literature on the role of AMH in pediatric practice. Materials and methods. A review of the literature in PubMed was conducted, limiting itself to articles in English and updating the search in February 2022. The search term was “anti-Mullerian hormone”. A total of 437 manuscripts were found, including 37 review articles. The search was gradually narrowed with filters of clinical trials and systematic reviews to 75 articles. The references of the original and review articles were then checked to ensure a complete review. AMH is responsible for the differentiation of the gonads, provokes the regression of Mullerian ducts in the male fetus, correlates with karyotype, sexual development, levels of luteinizing hormone, follicle-stimulating hormone, and its serum levels reflect the ovarian reserve in women, even in childhood. Serum AMH is high from prenatal life to puberty. In postnatal period, the secretion of AMH by the testes is stimulated by follicle-stimulating hormone and strongly inhibited by androgens. AMH is of clinical value as a marker of testicular tissue in men with differences in sexual development and cryptorchidism, as well as in the assessment of persistent Mullerian duct syndrome. Determination of AMH is useful for assessing the function of the gonads without the need for stimulation tests and guides the etiological diagnosis of childhood male hypogonadism. In women, AMH is used as a prognostic marker of ovarian reserve and fertility. The use of criteria developed for adult women is problematic for adolescent girls, as clinical signs associated with polycystic ovary syndrome are normal phenomena of puberty. AMH can be used as an additional criterion in the diagnosis of polycystic ovary syndrome in adolescents. However, the lack of an international standard for AMH limits comparisons between AMH analyzes. Conclusions. AMH has broad clinical diagnostic utility in pediatrics, but interpretation is often complex and should be made in the context of not only the age and sex, but also the stage of development and puberty of the child. Recognition of the role of AMH beyond the development and maturation of the gonads may lead to new diagnostic and therapeutic applications that will further expand its use in pediatric practice.
