This method has me the most excited. It seems to marry the auto-immune cause and the hormonal cause. Hopefully Demo will talk more about his "T" theories on the other "thread" but in that case it seems as though higher "T" quickens the sperm production process which, for the reasons that Demo can surely explain better, shortens the POIS symptoms.
In the case of it's use for short-circuiting the auto-immune reaction, the theory is, we haven't really proved it yet, that stopping the production of sperm altogether, will not permit the auto-immune reaction to initiate.
As I usnderstand it, there's a relatively delicate balance, and that the two in combination, Testosterone and progestins, are much more consistently assured to stop this sperm production. Our hope is that when that happens, POIS will NOT appear. There are real hopes for it's success, because we have had some positive results with a different drug, Silodosin, that retains sperm.
So, if the combination doesn't work relative to the immune-system cause it still has a chance to work by establishing a hormone balance which has proven effective here already.
