Last paragraph rather rambling...
Some have recovered nicely with that surgery and high LH suggests that the testes really are the problem. Is this bi-lateral? If only one side, prospects are lower than both sides, suggesting that the other teste was not able to carry the load with LH=7.6
Low FT is leading to low E2 which makes sense. SHBG seems a bit high VS E2, so while liver is clearing E2 nicely, it is producing more SHBG that expected. But we do see a lot of variations in SHBG that are unexplained that may simply add up to individual variations.
Top end of HPTA is working well and E2 and prolactin are not getting in the way of LH production. FSH should be tested too, I am seeing a lot of LH only lately which is not wise from a diagnostic point of view.
