As an interesting point of reference, pre-varicocele these were my levels (just found these by chance):
- TSH: 0.63 mu/l
- Free T4: 15.8 pmol/l ( 9 - 24 )
Which converted is:
1.2275 ng/dL ( 0.61 - 1.12 )
I was always ridiculously thin but had no libido issues or anything at this point. As you can see, my level is at the top end of the range before varicocele.
As a side note, you can convert using this website:
This thread is worth checking out as well btw, @beak118 also has varicocele and similar issues:
