32, First T Test, Help Decipher Results


I recently went in to have my T tested due to low energy, (although I work 60+ hours a week physical work) and have some issues in the erection department. Everything looks good to me , except maybe the SHBG is a little high ? Results as follows

Total Testosterone 799 ng/dl
Free Testosterone 15.6 ng/dl
SHBG 43 nmol


It is often not as simple as that.
There can be more going on than TT, FT and SHBG
SHBG in your case may be from elevated E2 [estradiol].

Are you also finding that you feel the cold easier now?
Have you been using iodized salt to support thyroid hormone production?
See last paragraph in this post.

Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body’s temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.
