Usually with pituitary axis injuries the other hormones are affected as well and not just FSH/LH.

The FSH and LH being normal with low testosterone means there’s some kind of dysfunction. There’s an inverse relationship and if T is low LH should be higher to induce synthesis.

Sort of like in women’s menopause - when the ovaries run out of oocytes the ability to produce estrogen is gone and FSH/LH increase.

Anyways, obesity could be another issue. Adipose cells produce estrin and estrin has promiscuity with the estrogen receptor which reduces testosterone production. Another is elevated prolactin which has multiple causes and can reduce T production.

Anyways, my caffeine ranting is at an end. Good luck
