Abstract
The unfavourable outcomes of mobile phone use on male fertility have still not been fully elaborated. To establish the potentially adverse effects of everyday exposure to radiofrequency radiation (RF) on humans, we performed a controlled animal study that aimed to investigate the influence of RF radiation on rat testis histology as well as the amount, mobility, and structure of epididymal free sperm cell population. Eighteen adult male rats were divided into two groups of nine. One group comprised sham-exposed control animals, while the other group endured total body irradiation for an hour daily during two weeks. A 915 MHz RF field, power density of 2.4 W m(-2) and strength of 30 V m(-1) was generated in a Gigahertz Transversal Electromagnetic chamber. The specific absorption rate (SAR) was 0.6 W kg(-1). Body mass and temperature were measured before and after each exposure treatment. Immediately after the last exposure, the animals were sacrificed and testes removed and prepared for histological analysis. The free sperm cells were collected from the cauda epididymis and their quantity, quality, and morphology were microscopically determined using a haemocytometer. No statistically significant alteration in any of the endpoints was observed. This study found no evidence of an unfavourable effect of the applied RF radiation on testicular function or structure. Based on these results, we can conclude that short-time intermittent exposure to RF radiation does not represent a significant risk factor for rat reproductive functions.

Given the conflicting data reported by the relevant literature, our study attempted to investigate the influence of RF radiation derived from conventional cellular phones on the histology of rat testes and the amount, mobility, and structure of epididymal free sperm cells
The findings of the present study suggest that totalbody short-time intermittent irradiation of male rats with a 915 MHz RF field for an hour per day during two weeks did not result in significant disturbances of testicular function or structure
Summary
The unfavourable outcomes of mobile phone use on male fertility have still not been fully elaborated. To establish the potentially adverse effects of everyday exposure to radiofrequency radiation (RF) on humans, we performed a controlled animal study that aimed to investigate the influence of RF radiation on rat testis histology as well as the amount, mobility, and structure of epididymal free sperm cell population. The unfavourable outcomes of mobile phone use on male fertility have still not been fully established, as studies have revealed a wide spectrum of possible effects, ranging from insignificant ones to inconsistent degrees of testicular damage [5]. Given the conflicting data reported by the relevant literature, our study attempted to investigate the influence of RF radiation derived from conventional cellular phones on the histology of rat testes and the amount, mobility, and structure of epididymal free sperm cells
