If my memory is correct 40-60% of males with diabetes have low testosterone. I have diabetes, hbp,high cholesterol,low testosterone, enlarged prostate, ed and now Peyronie's disease. I had been able to be close to normal with medication except for Peyronie's. Testapel implants really help and also helped lower A1C . I understand certain meds. affect people differently.
I'm 59 . ED started around 38 finally had testosterone check early 50's it almost cost me a marriage. The other issues slowly appeared starting mid 40's.
Definitely get different doctors. Sad some Drs are arrogant and next one is on the ball knows he's stuff and doesn't work for insurance company . I've farmed my whole life and now have off farm job also. Don't remember a bad veterinarian and there patients don't talk. Some doctor's you just shake your head and wonder how they passed the test.
