Cholesterol content in the blood serum and the testicular tissue of male buffalo calves was estimated from birth to sexual maturity at 17 stages. Overall mean level in blood serum and tissue, respectively, were 61.92 mg% and 7.20 mg/g, for total 9.79 mg% and 3.60 mg/g for free, and 52.13 mg% and 3.60 mg/g for ester cholesterol. The free cholesterol formed only 15.81% of the total cholesterol in serum but formed 50% of the total cholesterol in the tissue on an average. On day 420 (around puberty) peak ester cholesterol was in the testis. The testis structurally presented a large number of spermatocytes in the seminiferous tubules and increased activity of Leydig cells in the interstitial spaces. In the tissue the cholesterol got reduced in the postpuberal phase probably due to its utilization for androgen production. The results revealed an association between the testicular cholesterol and serum cholesterol on the one hand, and the formation of spermatids and spermatozoa in gonads and matured behaviour of bull calves on the other
