I can't pin it down when it started, but it seems to have been going on for a while. I have very little desire for sex w/my wife, I am always tired, a lot more irritable, and when I DO have sex, my erections never last long.<br> <br> I decided to go see a Urologist. He sent me for a blood test and I just got the results, but I have yet to see the Dr. again b/c my appt. is next week.<br> <br> The results were as follows:<br> <br> FSH - 3.3 (1.6 - 8.0 mIU/mL reference)<br> LH - 6.5 (1.5 - 9.3 mIU/mL reference)<br> Prolactin - 7.3 (2.0 - 18.0 ng/mL reference)<br> Testosterone, Total - 132 (241 - 827 ng/dL reference)<br> Sex Hormone Binding Globulin - 11 (7 - 50 nmol/L reference)<br> <br> I am not a doctor, but I can easily see my testosterone is LOW.<br> <br> Should I be worried about anything (i.e. causes of low testosterone) and what should I be asking the Urologist next week?
