Abstract: The authors tested the contents of testosterone and estradiol in plasma of sika deer during every stage of growth of deer antler by radioimmunoassay in 1984. The role of sex hormones in the growth of deer antlers was discussed.17 male sika deer from deer farm of the Institute of Special Products,Chinese Academy of Agricultural Science, were divided into 3 age groups.The first group had 6 individuals (8 years old), the second 5 individuals (4 years old), the third 6 individuals (3 years old) .In velvet, the contents of testosterone differed greatly from that of estradiol, the testosterone level was low and the estradiol high during the fast growth period of pilose antler.In olssification and antler bony period,the contents of testosterone and estradiol increased fast.The authors considered that there was a cooperation of testosterone and estradiol in the growth of deer antler,the pilose antler could become bony antler thoroughly only when the two sex hormones increased at the same time.
