I have an artificial heart valve with extrememly low t-level 63 years old. On blood pressure medicine and crestor. Extremely low t-level, low energy, extremely low libido. Had a recent hospitalization for enlarged prostate (14 months ago) and had to have a cath for 10 days to aid in passing urine. Now my PSA is 0.24 and my doctor wants me to try Axiron for 3 month test. I'm concerned about side effects and the benefits of taking a t-supplement again (I was on Andro-gel for 9 months prior to the hospitalization with only moderate results).
