Morphometric Parameters of The Testis of 6-Month-Old Rats in The Norm and Under Radiation Exposure

Abstract

Assessment of the morphofunctional status of the testicles in chronic radiation sickness after prolonged exposure to ionizing radiation, comparison of the morphometric and morphological characteristics of these organs with different intervals and, thus, the development of an optimal algorithm for prevention, diagnosis and treatment are among the priority tasks facing scientists. The aim of the study to reveal the age-related morphofunctional features of the testes in radiation sickness. Methods. An experimental study was carried out on material taken from the testes of white non-linear rats. Animals were divided into 2 groups (n=64): Group I - (intact) control (n=33); II - group - rats that received radiation for 20 days from 71 days of age at a dose of 0.2 Gy (total dose was 4.0 Gy) (n=31). Results. Morphometry of the testicles showed that their mass, length and thickness in postnatal ontogenesis change unevenly. Comparison of the rate of weight gain and body length with the weight and volume of the testicles shows that with an increase in their volume, body weight increases more than length.
