abstract：:Basal growth hormone (GH) levels are higher in female than male primates, and estradiol (E) treatment of gonadectomized primates increases serum GH. To determine if the effect of E is mediated at the level of the somatotroph, we verified the effect of E-treatment on serum GH in spayed macaques, and then examined the e...
