Your thyroid numbers do -not- indicate any thyroid issues.  Yeah, your TSH is a bit on the high side, but it's still in range.  Can thyroid issues trigger libido issues too?  Yes!  In your case though, I seriously doubt it.


In my case, I have Hashimotos.  At one point, FT4 and FT3 were in the dirt and TSH was around 27.  It took me almost 5 years and 4 docs to finally get it all under control.  Now my FT4/FT3 are in the upper high of in range and my TSH is at a comfortable 0.8.  This was a major contributor to my "issues".  Once I had that settled, THEN I could focus on TRT (I'm 60 by the way).  Once I had this under control, libido issues subsided.


Oh, and TRT can also be over-done!  I've found that I feel my best when I keep free-T in the upper 1/3 of in range and my E2 is around 25-ish.


I've tried iodine in the past too.  Was using Lugol's Solution.  I'd add a few drops to some orange juice in the morning.  Boy howdy, that brings on some good energy...but it can be over-done!  I found that if I took too much iodine, I would get stuffy.  I had energy but still felt like sxit.  Now?  Just 4 to 5 drops of Lugol's in some orange juice a few times of week seems to work best for me.  Iodine can and will affect thyroid function.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
