You need to screen for diabetes with fasting glucose and A1C as low SHBG can be from that condition, but also not.
Sometimes high or low SHBG is not explainable.
With low SHBG, your %FT is increased and there is less SHBG+T and TT is reduced. So your T status will be higher than TT implies.
With FSH much higher than LH you should have your testes screened for testicular cancer - a young man’s disease. Your screening did not show this.
You have signs of primary hypogonadism, your testes are not working very well. Varicocele perhaps.
Thyroid problems are seen very often here. Most often thyroid labs are normal, but lab ranges are rather useless. Most often problems involve not using iodized salt or other sources of iodine. Families can be affected by not using salt or not using iodized salt.
Find 5,000iu, yes 5000, tiny oil filled Vit-D3 capsules. You body makes Vit-D3–>Vit-D25 that is essential for proper gene expression in your body. Vit-D3 RDA’s will prevent crooked bones in children but the RDA is absolutely inadequate and sub-optima.
Anyone else in your family affected by some of these issues?

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.

I can be a bit abrupt in my replies and recommendations. I have a lot of ground to cover as this forum has become much more active in the last two years. I can’t follow threads that go deep over time. You need to respond to all of my points and requests as soon as possible before you fall off of my radar. The worse problems are guys who ignore issues re thyroid, body temperatures, history of iodized salt. Please do not piss people off saying that lab results are normal, we need lab number and ranges.
The value that you get out of this process and forum depends on your effort and performance. The bulk of your learning is reading/studying the suggested stickies.
