Low LH with normal Testosterone experiencing low T symptomps

here's my recent bloodwork (the attached bloodwork is the most current one), I attached the bloodwork here. I took another bloodwork last year and my LH were 1.25 and Total Testosterone were 550 (not attached).

The bloodwork is taken approximately 3.5 weeks after the cessation of SERMS (Torem 40mg+5mg Nolvadex ED for 8 weeks). I also believe that this bloodwork is a little skewed upward with a little after effect of the SERMS.

The symptoms that I am experiencing are low libido, difficulty maintaining an erection, brain fog, and anxiety. Also fatigue even after sleeping for 8-9 hours so decreased sleep quality i guess.

I'm now at a point where I want to evaluate if TRT can be an option. Questions:

1. What conditions can cause low LH levels with a "normal" testosterone level? I read that this can be due to tumors in Pituitary...
2. Are low LH levels enough to diagnose secondary hypogonadism, even when Testosterone level is normal or low normal?
3. Does one need to have fairly low level of Testosterone to be considered for TRT?

Any advice is much appreciated.

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.
