5-androstenedione is structurally similar to 4-androstenedione, with the exception of the positioning of a carbon-carbon double bond. 4-Androstenedione is a prohormone which is naturally produced in the body by the adrenal glands and gonads, and acts as precursor to testosterone, as well as estrone and estradiol.
