Please help me determine cause of my Low T.
4 years ago, for no real reason other than that I have trouble building muscle, I asked to add Testosterone to my annual blood work for my physical. I was not experiencing any typical low T related symptoms. I was surprised to find out that my Total Testosterone was very low (168). I was referred to an endo who ran labs and did an MRI and determined that everything was normal except T level. He prescribed TRT gel. I did some research and asked the endo to put me on Clomid instead as I still wanted to have more children. He was hesitant but eventually caved and prescribed 25mg every 3rd day.
The clomid raised my T levels to 759. After 4 months, he had me go off Clomid to see if that remained higher and I was back down to 150. Ever since I have been on Clomid and hovering around 600. Every time I have an appointment I ask about a possible cause, and he says sometimes there isn’t one which I find to be a lazy or uniformed answer
Recently, I have been interested in finding out what may be causing it on my own, instead of just taking clomid for the rest of my life. I am in good shape and eat fairly well. I currently take 5000IU of vitamin D and Clomid, nothing else.
Here are some of my lab results:
Before Clomid:
Dec '12
Estradiol 14.8 (7.6-42.6)
PSA .8 (0-4.0)
TT 168 (348-1197)
Hemocrit 41.6 (37.5-51)
Jan '13
SHGB 16 (10-50)
Albumin 5.4 (3.5-5.2)
fT4 1.37 (.8-1.8)

LH 1.6 (2-6)
TSH 2.6 (.4-4)
FT 43.7 (35-155)
TT 180 (250-1100)

TT 759 (250-1100)
Jul '14
FT 122.4 (35-155)

Before I go to my Endo for my annual appointment, I would like to know what additional tests I need to take. What can I do to diagnose the cause myself? Should I just stay on the Clomid and forget about? What else do you need to know to help me?
Thanks to anyone who can guide me along.
