Morphological Parameters of Rat Testes in Normal and Under the Influence of Chronic Radiation Disease

In this work objective was to study the morphological parameters of the testes of rats of 3 months of age in normal condition and under the influence of chronic radiation disease. The study was conducted on 40 white randomly bred male rats, weighing from 95 to 120 g, divided into 2 groups. Chronic radiation sickness was induced by irradiation of rats (4 Gy). Animals were removed from the experiment at 90 days of age, 20 days after its inception. Mathematical processing was also performed in which the standard deviation and representativeness errors were determined. An analysis of the results showed that in rats of the experimental group exposed to radiation (chronic radiation sickness), at the sexually mature (90 day) age, the diameter of convoluted seminiferous tubules is 8% less than the control, and their cross-sectional area is 13% behind. Other anatomical parameters, such as the mass of the testes lag behind by 8%, the length of the testes by 6%, the thickness of the testes by 5% and the volume of the testes by 10%, respectively. It has been established that after exposure to chronic radiation, puberty is delayed and all the morphological parameters of the testes lag behind.
