Δ4-Androstenediol is an androstenediol that is converted to testosterone. The conversion rate is about 15.76%, almost triple that of Δ4-androstenedione, due to utilization of a different enzymatic pathway. There is also some conversion into estrogen, since testosterone is the metabolic precursor of the estrogens.
