I think it means that "Type 3 3alpha-hydroxysteroid dehydrogenase (aldo-keto reductase 1C2, aka-AKR)" neutralizes 5alpha-dihydrotestosterone (DHT). Where you can get "Type 3 3alpha-hydroxysteroid dehydrogenase (aldo-keto reductase 1C2, aka-AKR)" is a mystery to me. It is also unclear to me what the total health effects would be.

However, it may be that certain SSRIs might provide it. http://en.wikipedia.org/wiki/3-alpha-HSD

Unfortunately, the last thing I would recommend is taking SSRIs, unless your really, really need them.
