levels of 5α - DHT are indicative
of over-inhibition
of 5α - reductase (5AR), the enzyme that converts testosterone to 5α - DHT, which is ~ 2 - 3 times as potent as testosterone due to 5α - DHT's greater affinity for
androgen receptors.15
When testosterone is given, the need to compensate via increased production
of 5α - DHT is removed; the
androgen receptors are now also being activated by testosterone, resulting in signaling for reduced synthesis

of 5α - reductase activity, 5α - DHT
levels and its metabolism to 3β - adiol.
