Hypoplasia of the undescended testicle: qualitative characteristics based on morphology and electron microscopy

The purpose of the study is to study the histological and ultrastructural characteristics of testicular hypoplasia in cryptorchidism in children. Materials and methods. Morphological (light-optical microscopy) and electron-microscopic studies of 36 biopsy specimens of the tissue of the neoplastic testis with unilateral cryptorchidism (inguinal retention or ectopia) were performed in accordance with the modern research data algorithm using the following equipment: microtomy was performed on a HM-450 MICROM microtome; the morphology and morphometry of the preparations was performed on a Olympus CX41 microscope with magnification x50, x100, x200, x400; ultrathin sections were obtained on a Leica EM UC6 ultratome and examined using a Morgagni 268 electron microscope. To assess the degree of hypoplasia of the testicular tissue, morphometric indicators were selected that characterize the condition of the seminiferous tubules: average diameter of the seminiferous tubules, number of layers of germinogenic epithelium, number of Sertoli cells per tubule and tubular index fertility Statistical analysis was performed based on the Gretl software package (Gnu Regression, Econometrics and Time-series Library 2014)...
