title: Effect of experimental microvascular orchidopexy on spermatogenic cell differentiation in the testes of the dog.
abstract: Experimental microsurgical orchidopexy was undertaken in 15 healthy mongrel dogs by anastomosing the testicular artery and vein to the ipsilateral caudal epigastric vessels. At pre-selected post-operative intervals of 4 weeks, 5 or 8 months the results were morphologically and histologically evaluated by the 'testicular biopsy score count' method. This method is based on the presence of the main spermatogenic types arranged in order of maturity. Between the mean scores of the normal and the operated testes there was a significant difference. The differentiation of the spermatogenic epithelium of the reconnected testis is slightly hampered, but not seriously.
