You should have DHEA-S tested to eval DHEA status. DHEA causes first hair growth, pubic and arm pit.
You seem to have a mix of primary hypogonadism [testes] and secondary [pituitary]. Prolactin is not causing low LH/FSH, but something else could be the problem in the pituitary and a MRI may show a non prolactin secreting adinoma. Blows to the head can also damage the pituitary and you can try to recall such events from years ago.
Some cases of this nature can involve a genetic component and testes can be ordered. Some involve simply looking at chromosomes with a microscope. There can also be problems with T receptor response or DHT receptors.
TSH is nice, but there is more to the equation that that. Please see below re oral body temperatures and iodine.

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.
