title: [Correlation between tissue ultrastructure changes of small testis and sex hormone].
abstract: OBJECTIVE
  To investigate the tissue ultrastructure changes of small testis and sex hormone and their correlation.
  
  
  METHODS
  The patients were divided into small tests (n = 8) and control group(n = 12). FSH, LH, T were determined by radioimmunassay. Diameter and wall thickness of convoluted seminiferous tubule were investigated with light microscope and electro microscopy on small testis tissue morphology and ultrastructure.
  
  
  RESULTS
  FSH, LH, T of small testis and control group were (21.05 +/- 9.15) IU/L vs (6.74 +/- 3.52) IU/L, (22.88 +/- 6.25) IU/L vs (6.60 +/- 1.48) IU/L and (0.30 +/- 0.04) nmol/L vs (17.55 +/- 9.25) nmol/L, respectively. Seminiferous tubule diameter and wall thickness were(37.33 +/- 6.80) microns vs (198.46 +/- 29.84) microns and (10.30 +/- 1.82) microns vs (2.95 +/- 0.20) microns. Small testis tissue ultrastructure changed significantly.
  
  
  CONCLUSIONS
  Pathologic changes of small testis tissue in many parts such as seminiferous tubule, germinal epithelium, Sertoli cell, Leydig cell, limiting membrance and blood vessel may relate with genetics and immunoreaction.
