Age peculiarities of morphological parameters of sperm in rats

E. V. Shcherbak, N. M. Brechka

The paper studied the effect of age of rats on androgen bodies and on the qualitative and quantitative indicators of sperm. In the experiment used 60 Wistar rats were divided into eight age groups: 2,5 months, 3,5 months, 6 months, 12 months, 18 months, 24 months, 30 months and 36 months. It was, revealed that the mass of androgen bodies remained almost unchanged, despite their slight variations in physiological limits, if a control group of animals to take the reproductive period of life (6 months). The number of sperm in the groups studied animals with age did not decrees. But while there was a significant increase in the level of pathologic forms (almost 3 times) and reduced mobility in 30 and 36 month-old animals. At 18 and 24 month-old animals was observed agglutination of low degree, and in 30 and 36-month agglutination was observed as low and secondary degree.
