[Morphofunctional evaluation of the testes in cryptorchism].

E D Cherstvoĭ, P P Soldatenko

    Summary

    Undescended testes (cryptorchism) show age-related morphological changes, particularly in seminiferous tubule size. Hormonal disturbances affecting the pituitary and Leydig cells are key factors in its development.

    Area of Science:

    • Reproductive Endocrinology
    • Developmental Biology
    • Pediatric Urology

    Background:

    • Cryptorchism, or undescended testes, is a common congenital condition with significant implications for male reproductive health.
    • Morphological changes in the undescended testis occur with age, impacting testicular development and function.

    Purpose of the Study:

    • To investigate the age-related morphological alterations in abdominal and inguinal cryptorchism.
    • To identify key morphometric indices for assessing changes in undescended testes.
    • To explore the role of hormonal disturbances in the pathogenesis of cryptorchism.

    Main Methods:

    • Morphometric analysis of undescended testes from fetuses, newborns, and infants up to one year of age.
    • Evaluation of seminiferous tubule size, surface area, and relative volume.
    • Assessment of Leydig cell presence and anterior pituitary hormonal influence.

    Main Results:

    • Significant age-dependent morphological changes were observed in undescended testes.
    • Seminiferous tubule surface area and relative volume were the most informative morphometric indices.
    • A notable absence of Leydig cells was found in undescended testes of fetuses, newborns, and infants with congenital abnormalities.

    Conclusions:

    • Hormonal disturbances, particularly involving the anterior pituitary lobe and Leydig cells, are critically important in the development of cryptorchism.
    • The findings highlight the need for early diagnosis and intervention to address potential hormonal imbalances and developmental abnormalities associated with cryptorchism.
