Immunoexpression of Androgen Receptor and Nine Markers of Maturation in the Testes of Adolescent Boys with Klinefelter Syndrome: Evidence for Degeneration of Germ Cells at the Onset of Meiosis

Abstract excerpt

CONTEXT: The pathogenesis and mechanisms behind the degeneration of the seminiferous tubules in testes of subjects with Klinefelter syndrome (KS) are yet unknown. OBJECTIVE: The objective of this prospective clinical study was to characterize the testicular degeneration process during puberty in boys with KS by describing the immunoexpression of some developmentally regulated markers of testis maturation in...
