119,120 The bioavailable levels of testosterone in the testis far exceed those required for function as the binding affinity of testosterone for AR is approximately 1 nM, and the levels of testosterone required to regulate gene expression via AR binding to gene regulatory regions are 1–10 nM....
Testosterone binds with high affinity to SHBG and with substantially lower affinity to albumin, CBG, and orosomucoid. The term bioavailable refers to that fraction of circulating testosterone which is not bound to SHBG and reflects the belief that non-SHBG bound testosterone, being bound with low ...

Testosterone bound to SHBG is essentially "inactivated," meaning it's unable to exert any cellular action. On the other hand, your bodycanutilize testosterone bound to albumin and free testosterone—that is, bioavailable testosterone—at the target tissue level. ...
