Danazol will not alter your hormone levels in a major way. It's not like adding external doses of testosterone for instance.
The bigest risk by far of Danazol, is that it's a 17 alpha-alkylated compound. It's been chemically armor plated against liver breakdown. This means that the liver can't break down the compound into metabolites on the first pass, however it will still try, causing damage in the process. Damage caused on such a short course of a 17aa compound however is minimal.
It is designed for women, correct. The raising of LH from using it is so slight that it will unlikely produce any noticable effect in men. I was merely speculating why the doctor may have prescribed it, not saying he was correct. Hope has already said he's had hormone levels checked and they were "fine". Not knowing what the results were they could very well be almost falling off the edge of normal range.
Either way IMO Danazol for gyne is a joke. Using it to treat anything envolving a male patient isn't going to result in anything.
As for drugs to reduce gyne, Fermara (letrozole) is effective in some cases, and not just steroid induced ones. The Idea is you starve the breast tissue of oestrogen to reduce its size. Due to its very nature, breast tissue has an abundance of oestrogen receptors. When too much Oest is present, it binds to them and triggers excessive growth.
There reaches a point where there is no longer enough oestrogen to induce growth, and the growth stops. Even after leveling off of hormone levels, say after puberty, there's sometimes still enough oestrogen to keep the existing tissue "ticking over". By eliminating the vast majority of oestrogen from the body, the receptors are no longer having oestrogen being bound to them, in theory causing the tissue to regress. it's certainly not going to shrink 36DD's by much, but it may well work for glandular gyne.
