The effect of expose the rat testis to low level laser light on changing serum LH and testosterone levels

Abstract: 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.
