MORPHOFUNCTIONAL STATE OF REPRODUCTIVE SYSTEM IN WHITE MALE RATS UNDER CONDITIONS OF INFLUENCE OF LOW INTENSITY ELECTROMAGNETIC RADIATION
The purpose of the paper was to study the effects of low intensity electromagnetic radiation on morphofunctional state of testes in white rats as well as some biochemical indexes of different units of reproductive system in the animals. White male rats weighing 215-240 g were subjected by microwave radiation with frequency of 42 GHz during 30 days for 30 min. daily. The level of lipoperoxidation in the tissues of testes and mediobasal hypothalamus as well as the testosterone and luteinizing hormone levels in blood plasma were determined. Morphofunctional state of epididymal spermatozoa and testicular tissue were studied. Under conditions of low intensity electromagnetic radiation, peroxide haemolysis of erythrocytes has been found to increase that testifies to oxidative stress development. The hormone levels of testosterone and lutropin have been found not to differ trustworthily from that of the control indexes. The relative weights of gonads and pituitary under experimental conditions were compared with the control group. The intensification of free radical oxidation processes was determined in testicular tissue, which correlated with the worsening of morphofunctional state of epididymal spermatozoa. The leading disorders were broken and lost tails of spermatozoa. Under the influence of the electromagnetic radiation, the increase of the total number of Leydig’s cells took place, which may be connected with the resonance effect. Therefore, low intensity electromagnetic radiation does not affect steroidogenesis considerably while it causes morphofunctional changes of spermatozoa.
