50 yr old male needs input

[Guest guest]

Recently I had a full battery of blood tests for a physical. I had been

feeling run down, forgetful, low libido etc. I was shocked to find out

that my testosterone and free test were on the low side. 285 ng and .7

for free test. It is completely devastating to find out that my nuts

are not functioning properly. LH and FSH were on the low side of

normal. My thyroid tests came back within normal limits but the Doc.

says that I have a nodule on my thyroid and ordered a sonogram he says

that its probably nothing but wants to make sure. What the hell could

be causing the low T? Where do I go from here? I feel like a girlie man.

Thanks for your input
