I'm suffering all the classic symptoms of low testosterone. I've been messed around by GPs for 6 months now so would really appreciate some independant input. Here are my lab results;
Total Testosterone (03/2013) - 13.1 nmol. [ref. range; 8.8 - 36.7]
Total Testosterone (07/2013) - 23.4 nmol. [ref. range; 8.8 - 36.7]
Free Testosterone - 5.55 pg/ml - [ref. range; 8.8 - 27]
SHBG - 77 nmol - [ref. range; 20 - 60]
Cortisol, Folate, Thyriod Stimulating Hormone, Free Thyroxine, Free T3, Follicle Stim. Hormone, Luteinising Hormone, Prolactin, Growth Hormone, B12 - were all within normal range.
When I asked my GP about SHBG, he said it was a problem but he didn't know what could be done about it. I asked if it may implicate high estrogen inhibiting testosterone, he said maybe but he'd have to ask the lab if I was eligible for estrogen testing.
My knowledge of the mechanisms of SHBG is limited, but a cursory Google search brings up the drug Proviron (Mesterolone) as being used to reduce it. I want to learn about the implications of this, what causes high SHBG, and whether bringing it down may help my issues with libido and fatigue. I have never had any TRT. Thanks.
