عنوان انگلیسی P-7: Effects of Long-Term Exposure to Radiofrequency Radiations Emitted by Common Mobile Jammers on Sperm Quality Parameters in Rat
چکیده انگلیسی مقاله Background: Exposure to electromagnetic fields (EMFs) by using electrical machines, tools, industrial instruments, power lines, and communications devices has occurred as a result of technological developments and is causing a threat to normal lives. The aim of this study was to evaluate the effects of long-term exposure to radiofrequency (RF) radiations emitted by mobile jammers.on sperm quality. Materials and methods: Thirty adult male rats were randomly divided into control, sham and experimental groups. Experimental rats were exposed in the restraint tube to radiofrequency radiations emitted by mobile jammers at a distance of 100 cm, for 40 days, 5 days/week, 7 h/day. Sham group was placed in restraint tubes same as experimental group, without radiations. The control group was allowed to freely move in the cages, without radiations. Weight (before and after experiment) and volume of testis (cm3) of the animals were measured. Furthermore, to evaluate sperm counts, motility and viability, epididymal semen samples were collected and incubated for 40 min at 37 ˚C in 1 mL of PBS. Data were analyzed by using one-way ANOVA. P< 0.05 was selected significant. Results: In the sperm quality evaluation, percentage of sperm viability in experimental group exposed to jammer RF radiation was significantly lower than that of sham-exposed rats (P< 0.05). Moreover, the motility of sperm in sham group after subjected to restraint stress was significantly lower than that of control groups (P< 0.05). However, there were no significant different in sperm concentration, weight and volume of testis of the animals between groups (P>0.05). Conclusion: These findings lead to the conclusion that restraint stress or long-term exposure to radiofrequency radiations emitted by mobile jammers may significantly decrease sperm quality.
