I posted my situation regarding erectile dysfunction in the site below and I got the reply from the doctor…
I’m not good at understanding Hormones , DHT , Testosterone and all these kind of stuff. 
cure-erectile-dysfunction.org/er … opecia/235
I mailed him to send his contact information so that I can contact him in person.
Is there any thing else that I should ask?
Seems to me he understands what the root of the problem is…DHT…I posted a comment to see if he understands what 3-adiol G is.
Here is his reply to my question.

My guess is that the temporary lowered DHT levels and ruined homeostasis may have altered numerous gene expressions for improper Glucuronosyltransferase release, that in turn may have lead to chronically low 3-Androstanediol glucuronide levels. However, this is just an assumption.
What exactly is this website and what are the credentials of this “Dr. Richard”? I can find no info on him, and the site looks an unprofessional spam blog, similar in tone and writing style as Dr. Lin from actionlove.com. In fact, that appears to be what it is, considering HE SELLS PRODUCTS AND SUPPLEMENTS through PAYPAL, designed to “cure” people’s situations who ask him for help:
cure-erectile-dysfunction.org/products
cure-erectile-dysfunction.org/he … ustion/298
cure-erectile-dysfunction.org/je … mptoms/289
From the above, it appears to be little more than a spam site written by an internet marketer masquerading as a “doctor”. Then again I could be wrong, but for now I would take whatever he replied with with a grain of salt.
