Also, when posting labs, ALWAYS include the normal ranges and the units. They differ by lab and by country, so a particular number may mean different things, depending on what the normal range is for that lab. For example, your prolactin is Prolactin 3.24 ng/ml, but how do I know that is high or low without a range to compare it to. For my lab, the "normal" range is 4.0-15.2 pg/mL, so your number falls below the normal range. However, your lab may have a lower end of the range, depending on methodology.
A GnRH challenge test might prove useful to see if your pituitary is responsive to GnRH. One question I forgot to ask is whether or not you've had any head injuries in the timeframe that things started going bad with the T? Head injuries, particularly whiplash, can damage the delicate blood vessel plexus connecting the hypothalamus (part of the brain where GnRH is made) to the pituitary (where it stimulates the release of LH/FSH). A GnRH challenge test might help to narrow the problem organ down to either the hypothalamus or the pituitary.
