The effect of expose the rat testis to low level laser light on changing serum LH and testosterone levels
In order to investigate the effect of low level laser light on changing serum LH (luteinizing hormone) and T (testosterone) levels, 24 male rats have 6 weeks of age, weighing about 200g of each were divided randomly into 3 groups, 8 rats for each. Group ? was exposed to 4 joules/cm²/day (50 mW × 10 sec), and group ?? was exposed to 12 joules/cm²/ day (50 mW × 30 sec) of laser light by 660nm wave length probe for five days. Group ??? was used as control. At the sixth day, the serum LH and T levels were measured and the right testes were taken for histopathological examination. The results showed that there was significant (P<0.05) decrease in serum LH level in group ?? when compared with group ? and control, while serum T levels were not significantly higher between groups, and there was clear histopathological changes in right testes seminiferous tubules of group ?? which exposed to 12 joules of laser light.
