Changes in serum estradiol, insulin-like growth factor-1, leuteinizing and testosterone levels, and leuteinizing hormone-stimulated testosterone production per testis in vitro from hatching to adulthood were studied in Korean native chickens of 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 21, 24, 28, 32, 44, 52 and 64 weeks (n=13 chickens per group) of age. The changes in the profiles of the levels in the incubation medium of luteinizing hormone-stimulated (100 ng/mL) testosterone secretion per testis in vitro, and the serum LH, testosterone, estradiol, and insulin-like growth factor-I were determined by radioimmunoassay.
