The present study showed a highly significant (P<0.01) positive correlation persisted between the thyroid gland and the testis in respect of their biometrical and micrometrical parameters in male Assam goats at different ages of postnatal life. The weight of the thyroid gland also showed a highly significant (P<0.01) positive correlation with weight of caput, corpus and cauda epididymides of the male goats at their various ages. Mean serum concentrations of Triiodothyronine (T3) and Thyroxine (T4) was found to possess a highly significant (P<0.01) positive correlation with diameter of the seminiferous tubules, height of seminiferous tubular epithelium and weight of testis. Again, the thyroid hormones had a negative correlation with the height of tubular epithelium of all the three segments of the epididymis. The increase in diameter of the seminiferous tubules was attributed by increased number of Leydig cells in the testis. The serum concentrations of testosterone hormone were found to have a positive correlation with various micrometrical parameters of the testicular tissue. Again, the serum levels of testosterone hormone showed highly significant (P<0.01) negative correlation with the concentration of serum cholesterol.
