I hope you get this figured out.
Did you have your E tested? I've heard of some guys having mysteriously high FSH & LH while other numbers were ok, never had more information on those unique situations, though.
May I ask how did you come to determine your prolactin levels were high and there was a pituitary issue? None of the clinics I've went to tested prolactin.
I came off T temporarily while switching clinics. My T was too high for the labs to record (over 1500ng/dL), which raised my estradiol to the normal ranges for ovulation. This happened after my period stopped, oddly. I was a HOT MESS (insomnia, panic, tremors, cold sweats). I need only a fraction of the dose most guys need - metabolism definitely isn't a one-size-fits-all thing. Lowering my dose was all I needed to do.
