You need to do lab for prolactin which suppresses LH/FSH if elevated/high. That can then be from a prolactin secreting pituitary adinoma. Pituitary can also be damaged by whiplash or blows to the head.
When do you feel that T levels became low?
Thyroid can sometimes do this. Test TSH, fT3, fT4 and check oral body temps - see below. If temperatures solid, skip the labs.
hCG can work with younger testicles. You could also try a HPTA restart, find the sticky.
High doses of hCG create problems and is expensive. Try 250iu subq EOD. Use #31 5/6" 0.5ml insulin syringes. 0.3ml seems too small to hand.
Most here are on injected T. You simply need to find out how you respond. You should be after high end of range for TT and FT and hCG may not do that.
Most are on T+AI+hCG. T+hCG does not present any fertility issues at all AV hCG only.
With low FT and E2=19, you may need AI [anastrozole] to keep E2 near 22pg/ml which is optimal for almost [not all] guys.

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.
