title: [Morphological changes of testicular tissues in rats of different age groups, depending on the time of being in the abdominal cavity].
abstract: Pathological changes in the testes of animals of different age groups with the experimentally simulated cryptorchidism were evaluated. Animals were divided into 3 groups according to the time of fixation of testes into the abdominal cavity for a term of 2, 3 and 4 weeks. The changes were recorded at the time of bringing down the testes into the scrotum and at 14th and 28th day after bringing down. An assessment of pathological changes and the dynamics of the reparative capacity of testicular tissue in animals of different age groups at different stages of the study was performed. Experimental cryptorchidism leads to marked degenerative changes in the testes, up to the destruction of the elements of the testicular tissue in both groups. Comparative analysis of reparative capabilities revealed that potential of recovery of testicular tissue in young group of animals is much higher than that of mature animals.
