What are the causes of andropause?

Only 2% of testosterone circulates freely in the blood. In fact, it mostly binds to two plasma proteins: albumin (weakly bound) and SHBG (strongly bound). The decrease in testosterone secretion is due to aging on the one hand, and a high level of SHBG or “sex hormone-binding globulin” on the other. This increase has the effect of removing usable testosterone from the bloodstream: it thus enhances andropause and its physiological manifestations.
