Do anabolic steroids lower SHBG?
We conclude that the detection of the SHBG-decrease following anabolic steroid administration seems to be a reliable, safe and simple test of androgen sensitivity.
Do androgens decrease SHBG?

Sex hormone binding globulin response to testosterone. An androgen sensitivity test Adequate distinction between an abnormality in androgen secretion or in target cell response is important in the diagnosis and management of male pseudohermaphroditism.

Is SHBG after hCG reliable as an androgen sensitivity test?
It is concluded that determination of serum SHBG after hCG is not reliable as an androgen sensitivity test, but the detection of the decrease in serum SHBG after exogenous testosterone is a useful and simple test of androgen sensitivity.
