You keep saying that stem cell treatment is in use to treat ED but that is still a very long way off, and certainly not something your doctor can just inject.
We don’t know if it’s ‘receptor damage’, that is what the studies will have to determine. In case it escaped your notice there have been no studies of PFS victims until very recently.
I have read studies that low T causes lack of sensitivity, as well as changes to structure, muscles etc. It also happens with some men getting androgen ablation treatment for prostate cancer.
Theoretically if someone can unlock some way we can reconnect to androgen output then a lot of these symptoms should reverse themselves substantially, if not fully. That’s what keeps me going anyway.
