Half of low T results normalize on repeat

追加: 2026-05-06

[00:00:00]Now again, we know that roughly half of initially low total testosterone levels will normalize on repeat testing without any sort of treatment. That's why this sort of confirmatory draw matters. Now, if the repeat draw confirms the first, LH and FSH can localize the problem. So, is it located at the level of the testes or is it somewhere in the brain? Is it somewhere else? And if you get a SHBG, that can tell you whether the total testosterone value may be misleading because of the binding protein being abnormal. Um so, you may also choose to get a free or bioavailable testosterone as a follow-up uh sort of step. This is usually reserved for cases where the SHBG comes back abnormal um or the total doesn't really match the clinical picture and you need that extra bit of information to make a decision. Although again, as you mentioned, the sort of mhm trial of testosterone replacement therapy is not really high-stakes in the short term, but um longer term it certainly can be.
