Pre-TRT, my FSH was 3.9 in a range of 1.5-12.4 (mIU/ml) from Lab Corp. LH wasn't tested, but TSH was 2.81 with range .450-4.500. Total T was 292 out of 348-1197. Because my FSH was on the lower range, does that mean I am secondary? I was never told anything by the doctor, who was horrible, and one of the reasons I quit TRT. I'm 36 years old, about 220 lbs, and am trying to figure out what has caused my T to be low in the first place.
