I have multiple symptoms which I am starting to believe might be low testosterone. I have lost most of the hair on my legs, have had extreme difficulty in getting an erection (which I feel like is due at least in part due to having prostate cancer many years ago and being treated with radioactive pellets which made me sterile, have been suffering from memory loss which seems to be getting worse, low energy, muscle definition is disappearing. These symptoms have evolved over the last 10 years but seem to be getting worse at a faster rate lately. Also the size of my limp penis has gotten quite a bit shorter overall, since I had prostate cancer surgery I have to take a medication for b.p.h. whenever I need it, I've also been having urine leakage issues more frequently lately like when I cough or simply laugh too hard.
