androgen + gi axis: what the current model actually says

tl;dr

• the androgen story is not collapse. it looks more like: 2023 high baseline -> 2025 lower plateau -> 2026 still normal but less abundant.
• the main reading frame is:
• TT + LH + T/LH = production / gonadal response
• SHBG + FAI + free T fraction = binding / accessibility
• free T + bioavailable T = actually available androgen pool
• T/E2 = balance signal, but context-sensitive
• the best current levers are not “testosterone supplements first”, but:
• sleep-airway quality
• recovery / overreaching
• energy availability
• autonomic stress

current androgen picture

• total T fell from the stronger 2023 baseline into a lower 2025-2026 range, but the shape now looks more like plateau than ongoing collapse.
• free T and bioavailable T are lower than the old baseline, but they do not support an overt low-T-first pathology.
• T/E2 looked ugliest in Dec 2025, then partially improved by Apr 2026.
• T/LH does not currently look like classic pituitary-gonadal failure; it looks more like a system that is still functioning, but not at the old “abundant reserve” level.

current GI picture

• fecal calprotectin = 426 ug/g
• stool multiplex PCR: EPEC detected
• HpSA negative
• visible parasite rows on the extracted page are negative
• current phenotype is unexpectedly quiet:
• normal stool
• no urgency
• no mucus
• no pain
• no recent worsening

what that GI pattern means

• this is not nothing.
• this is also not enough to declare chronic bowel disease.
• the cleanest current read is:
• a local GI inflammatory/infectious loop exists
• its current clinical burden may be mild, resolving, or partly silent
• it should be followed structurally, not dramatically

ranked hypotheses right now

1. low-grade / recent enteric infectious or post-infectious signal
2. local gut inflammation without proof yet of chronic IBD
3. training / recovery load helping drag ferritin downward
4. occult GI loss / absorption issue as a weaker but not closed branch
5. h. pylori as main story = weak
6. parasites as main story = weak
7. STD / sexual infection as gut explanation = very weak

what to check next

• wait for ceruloplasmin
• repeat fecal calprotectin
• if calprotectin stays high or symptoms appear, escalate into formal GI follow-up
• keep treating sleep-airway as a top-tier leverage layer because it likely pushes both androgen quality and recovery economics harder than another supplement theory

current doctrine in one line

the body does not currently look endocrine-collapsed; it looks like a system with a real sleep-airway burden, a real but clinically quiet GI inflammatory/infectious branch, and real room to improve androgen quality through recovery architecture rather than blind hormonal force.
