such temporally related behavior requires rapid production and removal of both 17-ketosteroids , processes which have been confirmed by tracer studies where it has been shown that in a two compartment system , androsterone has a t1/2 of 25 +/- 9 min for the fast component and metabolic clearance rate of 4050 +/- 1315 l per day ( n = 10 ) .
