Your DHEA-S is low!
Please get 25mg DHEA in vitamins shelves if in USA. Take with a meal that has more oils/fats and avoiding high fiber. Take fish oil and Vit-D3 the same way.
A1C is a problem. Diet should avoid all simple carbs such as subars, bread, rice, potatoes etc. You could try 500mg metformin per day. Very inexpensive, $40 per year at USA Walmart and others.
Is there selenium in your vitamins?
A1C affected by overall metabolic rate and AM cortisol should also be checked.
FSH is quite high relative to LH.
If/when you go on TRT, check LH/FSH one time then. Both should track near zero. If FSH does not, that could be from a FSH secreting testicular cancer.
rT3 looks very good, so we can remove that as a factor in your metabolism.
Prolactin does not seem to be a factor in low LH, TT, FT.
E2 was not tested and it can suppress LH, TT, FT.
However, SHBG is low and that normally suggests that E2 would be low, but we also know that diabetes can lower SHBG and your A1C indicates a problem.
A1C suggests metabolic problems. Would be good to also test AM Cortisol and Vit-D25. But take 5,000iu Vit-D3 per day and test to see where Vit-D25 is later.
With low DHEA-S, we are concerned with what else is going on in the adrenals is important. With good rT3 we do not expect to see adrenal fatigue.
