Effects of chronic exposure to 2G/3G cell phone radiation on in vitro maturation of bovine oocytes

摘要

Mobile phone use has arisen and rapidly been increased during last decades and therefore electromagnetic radiation or heat sourcing from mobile phones and its possible damages has become focus of interest. The aim of the present study was to investigate the effects of mobile phone signals on in vitro maturation of bovine oocytes. A total of 224 bovine cumulus oocyte complexes were matured in vitro and separated into two groups, and only treatment group received mobile phone signals for 100 min by calling 5 min/h. Following maturation period, oocytes were stained by fluorescent stain to assess maturation rates. The results showed that oocytes reaching Metaphase I and Metaphase II stage were 35.2 +/- 2.24 % and 48.2 +/- 2.21 % for treatment group whereas 11.9 +/- 1.45 % and 73.8 +/- 4.60 % for controls, respectively (P0.01). In conclusion, bovine oocyte maturation has been significantly reduced by mobile phone signals.
