To Jed Diamond:
I’m a student journalist who’s writing a column on male hormonal cycles.
Could you please give me the exact names of the studies that you mentioned in this article? (You said there are studies in United States, France, and Australia, what are those studies and who conducted those studies?)
About the monthly cycle, I’ve read on the Internet that men experience internal flow of blood from certain glands. But to my knowledge, glands do not have blood to produce. So could you please explain to me if that is true, and if not, then what actually happens to the monthly hormonal cycle in men?
Dihydrotestosterone (DHT) (referred to as androstanolone or stanolone when used medically) can also be used in place of testosterone as an androgen. The availability of DHT is limited; it is not available in the United States or Canada, for instance, but it is available in certain European countries, including the United Kingdom , France , Spain , Belgium , Italy , and Luxembourg .  DHT is available in formulations including topical gel, buccal or sublingual tablets, and as esters in oil for intramuscular injection.  Relative to testosterone, and similarly to many synthetic AAS, DHT has the potential advantages of not being locally potentiated in so-called androgenic tissues that express 5α-reductase (as DHT is already 5α-reduced) and of not being aromatized into an estrogen (it is not a substrate for aromatase).
