The present study providing data on circulating TSH, T3 and T4 concentration of Caucasian snake in the active seasons• The parameters of body length and weight were measured in the Caucasian male vipers (n=24) from Lar area in Tehran province• The serum levels of the TSH, T4 and T3 hormones were measured in the October- November, of 2014, by ELISA in the wave length of 450 nm• The results show that the mean values of the body length and weight of the male Caucasian vipers were 43•2 2.3cm and 427•5 45 g respectively• The circulating TSH, T4 and T3 concentration were higher during per-hibernating time in fall and lower in summer p( 0•001) during breeding season• Therefore a seasonal variation was observed in C• Vipers, thyroid function appears to be influenced by temperature, that may directly alter the hypothalamic-hypophysis-thyroid axis, and by reproductive activity, supporting a role for thyroid hormones in energy-demanding activities of animal.
