Low T, LH, and FSH-- what to do?
I'm 36 years old. July 31, my bloodwork showed:
Free Testosterone 4.1 (8.7-25.1)
My doctor said it was because of my vasectomy and started me on weekly testosterone injections, which I did for 3 weeks before stopping because of anxiety symptoms after the shots. I'm sorry I don't remember that dose. 1ml per week sounds right, but I'm not sure.
Since the shots were freaking me out, he started me on Testim 1% 50mg per day testosterone gel. I did that for 3 weeks. Then I got tested again and got this result:
Free Testosterone 4.4 (8.7-25.1)
So he upped my dosage to 100mg per day of a compounded cream.
Before I started the new cream, I had my LH and FSH tested and got this:
FSH 0.7 mIU/mL 1.5-12.4
LH 1.2 mIU/mL 1.7-8.6
Now he says that we should have tested those before starting testosterone treatment since treatment can push those levels down. Regardless, he's giving me 3 options:
1) Do nothing and assume the vasectomy caused the low T and that the T therapy caused the low FSH and LH.
2) Test to make sure I'm not producing too much prolactin, which apparently would indicate a pituitary tumor.
3) Have an MRI to look for a tumor.
What do you think? Is one of these options reasonable, or should I do something else? Also, I read somewhere that only high-dose T therapy would cause low FSH and LH. I'm positive I'm not on high-dose therapy, but what do you think? Should I stop the T therapy since it doesn't seem to be helping anyway, and then retest my FSH and LH after I've been off the T for a while?
