Serum concentrations of FSH and LH and the hypothalamic content of gonadotrophin releasing hormone (GnRH) were measured by radioimmunoassay in male rats maintained at 35 degrees C for various periods of time. The results show that heat exposure caused a temporary decrease in serum concentrations of LH and FSH which was associated with comparable changes in the hypothalamic content of GnRH. Histological examination of the adenohypophysis of rats exposed to heat for 42 days disclosed that the… CONTINUE READING
