in view of evidence , largely in animals , indicating effects of sex steroids on adrenergic receptors , we measured mononuclear leukocyte ( mnl ) beta 2-adrenergic receptors and adenylate cyclase sensitivity to stimulation by isoproterenol as well as platelet alpha 2-adrenergic receptors and sensitivity of sodium fluoride-stimulated adenylate cyclase to inhibition by epinephrine in 3 groups of normal humans with physiologically disparate levels of testosterone , estradiol , and progesterone ( 10 normal men and 10 normal women , the latter sampled in both the follicular and luteal phases of their menstrual cycles ) .
