The experiment established the long-term effects of low-intensity electromagnetic radiation from a mobile phone (EMR MP 1745 MHz, xpd = 7.5 ± 0.3 μW/cm2) in the offspring of male rats from parents, one of which was either subjected to a prolonged exposure of the investigated factor. A change in the sex ratio of the born offspring and a decrease in their body weight have been established. The analysis of the reproductive system of the offspring of males when they reached the age of 2 and 4 months, revealed significant impairments, with the most pronounced changes found in the offspring obtained from both the irradiated parents or when only the male was irradiated. These changes are manifested in the disruption of the normal functioning of the spermatogenic epithelium, namely, an intensification of the initial stage of spermatogenesis is noted, with a significant inhibition at the stage of spermatid transformation. A decrease in the number of mature germ cells – spermatozoa and a pronounced deterioration of their viability, as well as an increase in testosterone secretion is established. The revealed violations in the morphofunctional state of the reproductive system of the offspring suggest that the trans-generation effect of EMR exposure generated by cellular sources can be considered as a factor affecting the decline in the male fertility.
