[Effect of radiation leakage of microwave oven on rat's serum testosterone]

Since discovery of high frequency waves and their application in different industries, their adverse biological effects have been of great attention. Increased male fertility problems have suggested the possible role of microwaves in producing this disorder. Testes are active body tissues, which can be affected by these waves. Age of the patients at the time of the exposure can have important influence on the effect of these waves. Therefore, the aim of this study was to evaluate the effect of radiation leakage of microwave oven on rat serum testosterone at pre and post pubertal stages. In this study we used 18 mature [two months old] and 18 immature [one months old] rats. Mature and immature rats each were divided into control and experimental groups. Experimental groups were exposed to 2450 MHZ microwaves produced by a microwave oven, three times a day, each time for 30 minutes and control groups were kept in the laboratory under identical conditions in view of temperature and light. At the end of experiment blood was collected via heart puncture and serum testosterone was measured by RIA method. Collected data were analyzed by means of t-test. The result of this study showed that the level of serum testosterone in experimental group was less than that of control group in immature rats [P>0.05]. But in the mature rats, the serum testosterone level of experimental group was less than that of control group significantly [P<0.05]. Exposure to microwaves leakage of microwave oven resulted in decreased testosterone production by testes in mature rats which may be due to the direct effect of microwave on leydig cells or its indirect effect on pituitary and hypothalamus

Effect of radiation leakage of microwave oven on rat serum testosterone at pre and post pubertal stage

Since discovery of high frequency waves, their biological effects have been in great attention. Increased male fertility problems proposed their possible relation to use of microwaves. Testes are of very active body tissues, which can be affected by these waves. Age of exposure may also be an important factor. This study was carried out to evaluated testosterone level in rats exposed to microwave radiation at pre and post puberty. For this study 18 adult [2 month old] and 1.8 immature [1 month old] male rats were selected and each group divided in two groups, control and test group. Test groups were exposed to 2450 MHZ microwaves produced by microwave oven [LG Brant], three times a day, 30 minute each time. Control groups were kept in laboratory at same temperature and light condition. After 60 days blood was collected by heart puncture and testosterone was measured in serum by RIA method. Mean testosterone levels were compared by T-test. The results showed that in immature group testosterone has not changed significantly compare to control group; however in adult group this value was significantly decreased in test group in comparison with control [P<0.005]. Exposure to microwaves leakage of microwave oven decreased testosterone in adult male rats, which may be due to its direct effect on Leydig cells or indirectly through its effect on pituitary and hypothalamus
