We have lots of guys here with low-T at your age, not much comfort, but you are not alone. Your next step is these labs to try to understand the cause:
Labs:
TT
FT
LH/FSH
prolactin
CBC
hematocrit
fasting glucose
fasting cholesterol - can be too low
AST/ALT
If body temps are low:
fT3
fT4
Most USA States allow you to order your own labs and pay out of pocket via some WWW sources.

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.
