NORMAL MORPHOMETRIC INDICATORS OF THE EPIDIDYMIS OF WHITE OUTBREED RATS OF DIFFERENT AGES

Аннотация

In this article, the normative morphometric parameters of the testicles in the age dynamics of white rats are presented. Epididymal weight and dimensions: Small testicular mass (0.21 g) and its dimensions (length - 0.74 cm, thickness - 0.49 cm) are observed in newborn rats. As the rats get older, the mass, length and thickness of the epididymis increase. The highest values are achieved in 12-month-old rats: weight - 0.76 g, length - 1.3 cm, thickness - 0.9 cm. Epididymal tissue volume and density: Epididymal tissue volume also increases with age, reaching the highest values in 12-month-old rats (0.64 cm3). The density of testicular tissue decreases with age, which may be related to tissue development and changes in its composition. Correlation between body weight and testicular weight: Both body weight and testicular weight increase with age of rats, which shows some parallelism in their growth.
