The metabolic clearance rate of a steroid is defined as the volume of blood that has been completely cleared of the hormone per unit time. The production rate of a steroid hormone refers to entry into the blood of the compound from all possible sources, including secretion from glands and conversion of prohormones into the steroid of interest.
If there is little contribution of prohormone metabolism to the circulating pool of steroid, then the production rate will approximate the secretion rate.
