The investigation of rat testes was conducted to ascertain whether the testicular endocrine function bears any relation to the maturation of animal from the view point of morphological aspects. The ponceau-fuchsin stain was employed and the results were compared with those of Azan stain made for general histology.Interstitial cells are distinguishable as LEYDIG cells at approximately 1 month of age which corresponds to the puberty of individual animal. From this date onward mature LEYDIG cells show degranulation as well as the peripheral vacuolation. The granular interstitial cells differentiated from indifferential cells. Transformation into the LEYDIG cell involves nuclear changes as well as the acquisition of much cytoplasm which underwent an apparent sequence of modification. The disintegration of LEYDIG cells appeared first in a few of the large cells in the animals prior to the appearance of mature spermatozoa in a tubule.In an adult rat testis, various stages in the disintegration of LEYDIG cells were seen in the intertubular space, where a well-developed reticular framework is seen spread throughout the entire space. Whole cytoplasm of mature LEYDIG cells are filled with fuchsinophilic granules, on the other hand no fuchsinophilic, granular cells were seen in an immature rat testis.Thus the fuchsinophilic granules are seen abundantly around the degranulating cells and in the framework. Fuchsinophilia in the LEYDIG cells may be considered to be in close relation with the male hormone substance.
