I've had elevated LH for at least a decade (LH always above top of normal range). I asked my urologist what the long term health impact would be if I continued to have high LH. He said "nothing". Wow.
I'm making a list of potential negative health effects due to chronically elevated LH. Please post if you know of any that I miss, or if you have references in addition to the ones I list below.
