[Reaction of Reproductive System and Epididymal Spermatozoa .of Rats to Electromagnetic Radiation from Mobile Phone (1745 MHz) of Various Duration].

Changes in the weight of reproductive system organs, quantitative and qualitative indicators of the epididymal spermatozoa of rats on the Ist and 30th days after the end of an electromagnetic exposition from the mobile phone (1745 MHz, the 8 hour/day, power density 0.2-20 µW/cm²) of various duration (from 1 to 90 days) have been researched. A significant increase in the absolute and relative weight of the epididymis and seminal vesicles and the number of epididymal spermatozoa was revealed on the 1st day after electromagnetic expo- sure during 7 days. The increase in the exposure duration up to 14 days is accompanied by a fall of the above indicators, and after a longer exposure (30, 60 days) there is an increase of the absolute weight of the testes; in all other cases, significant deviations in terms of the weight of reproductive organs are not observed. Expo- sition of various duration at 1745 MHz, except for 7-day radiation exposure, had no significant effect on the amount of epididymal spermatozoa and DNA fragmentation in them; however, viability of mature male germ cells in irradiated animals decreases independently of the duration of exposure. The revealed disturbances of the researched indicators are mainly normalized in the remote period (on the 30th day) after electromagnetic radiation.

[State of the reproductive systemin in male rats of 1st generation obtained from irradiated parents and exposed to electromagnetic radiation (897 MHz) during embryogenesis and postnatal development].

The consequences of prolonged exposure to electromagnetic radiation from cellular phone (897 MHz, daily 8 h/day) in male rats of the 1st generation obtained from irradiated parents and subjected to prolonged exposure to electromagnetic radiation of the range of mobile communications during ontogeny and postnatal development were studied. It has been found that irradiation causes a decrease in the number of births of animals, changing the sex ratio towards the increase in the number of males. It had a significant impact on the reproductive system of males, accelerating their sexual development, revealed at the age of two months. Radiation from cell phones led to significant disproportions in the cell number at different stages of spermatogenesis. It increased the number of mature spermatozoa which decreased viability.
