I am a 54 year old male and have been experienceing fatigue and
decreased sexual desire. My testesterone levels are:
Total 498 ng/dL:(referece range 350-1030)
% free 1.2%: (reference range 1.5-3.2)
SHBG 69 nmol/L: (reference range 20-60)
Is testosterone replacement recommended?

Go to Yahoo Groups and join the forum Hypogonadism2 group..you'll
learn a lot!  Also, search hypogonadism on the web..it's something
that you may be experiencing.  you'll need more labs..like Lh/Fsh
(leutinizing and follicle stim hormones) as they are resp to tell your
testes to produce T.  if they are low u may have a problem with your
pituiatary gland (which sends the lh/fsh to your testes) and if they
are high than u may have a problem with ur testes producing T.

this is a macro overview..u'll learn a lot more on the forum.

Take care
Jack
