title: Morphometric study on leydig cells in capsulotomized testis of rats.
abstract: OBJECTIVE
  To further clarify the changes occurred in the testicular capsulotomized rats.
  
  
  METHODS
  In testicular capsulotomized and sham-operated rats, the cross sectional area, the nucleus diameter and the number of Leydig cells were morphologically analyzed by the Vidas Image Processing System connected to a microscope.
  
  
  RESULTS
  In the capsulotomized animals, the cross sectional area of Leydig cells was gradually increased from 30 days onwards. There was no obvious change in the nucleus diameter of Leydig cells. However, The Leydig cell number was significantly increased from day 30 onwards.
  
  
  CONCLUSIONS
  In rats, testicular capsulotomy may induce hyperplasia/hypertrophy of Leydig cells in the testis.
