Circulating testosterone levels
WebMost circulating testosterone is bound to sex-hormone-binding globulin (SHBG) and albumin, whereas a small proportion circulates as free testosterone. Decreased SHBG level is associated with increased risks for insulin resistance and metabolic syndrome, although it would also be expected to be associated with increased free testosterone level. WebThis is particularly so considering that bicalutamide increases circulating testosterone levels, and by extension gonadal testosterone production, by up to two-fold in males, and that only a small fraction of normal intratesticular testosterone levels, and by extension androgen action, appears to be necessary to maintain spermatogenesis.
