I took the advice from Ksman and went to an endo ( a different endo this time ) asking to get my thyroid checked. After checking my thyroid with ultrasound, it appeared perfectly normal, symmetrical, without any lumps of any sort. After getting a good look at me, my endo suspected some mild hypogonadism. As I said, I look drastically younger, and far less sexually developed than my peers. I'm almost 20, and still have no abdominal or facial hair, except for the armpits. So, I've got some tests done, and here are the results:
TSH 3.52 (ref. 0,40-40 ÂµIU/ml)
FT4 18.73 (12,60-21 pmol/l)
FT3 came back in the upper third of the range, but I can't find the result atm
Test 6.12 ng/ml (ref. 2.49-8.36)
Free testosterone 5.5 (ref. 5.5-42 pg/ml) !!!
FSH 2.26 (ref. 0.7-11.1 mIU/ml)
LH 3.58 (ref. 0.8-7.6 mIU/ml) (note: my LH came back below the range a few times in the last couple of years)
After this, my endo ordered a semen analysis ( not sure if this is the proper name of the test ) , and the results showed that I was fertile, not very fertile, but enough to impregnate a woman without any medical help.
After this, endo tried a pregnyl ( hcg ) stimulation test, and got my free T tested day after the shot. One thing I noticed, and this definitely wasn't a placebo, was that my testicles were about 10-15% larger and felt heavier after the hcg.
My freeT came back higher this time, it was 20 pg/ml !!!
So, my endo suggested me to start hcg monotheraphy, to see if I would notice any change on it.
Also, she believes that there is nothing wrong with my thyroid, and refuses to look any further into that.
I would also like to add that when I was a kid, about 5 years old I suffered a head trauma,
and I'm suspecting that this could have made me slightly secondary hypogonadal?
So, I'm asking for opinions, is freeT causing my problems or should I look further somewhere else?
(also, in the past couple of years series of endos tested a lot of things, and I couldn't write everything down, so, if you're interested in some results, other than the ones that are posted, feel free to ask)
