5-alpha reductase works on dht I believe. It is dht that is generally thought of as the major culprit in male pattern baldness. Presumably dht has some effect on libido .
Although the action mechanism is still unclear, previous animal studies have suggested that PSO may inhibit 5α-reductase, which produces DHT from testosterone [11, 12, 26].
Oh, yeah, I see what you're saying now.
In addition, DHT and prostate specific antigen (PSA) levels were not measured for identification of mechanism of PSO; therefore we could not explain the exact action of PSO on AGA patients.

Unfortunately, they did not measure DHT. Huh.
