Men's hormone balance

Male endocrine status as a system, not a single number. Free versus total, the SHBG that binds it, and the pituitary drive above it — three separable things that a single testosterone result cannot distinguish.

Reproductive axis increases it.

The finding that unifies all three nodes is that the same androgen does opposite things in different tissues: testosterone acts directly, and indirectly through intracellular conversion to dihydrotestosterone by 5-alpha reductase, as in prostate cells, and separately through estrogen effect when converted to estradiol by aromatase. Raise testosterone and you also raise DHT and estradiol - which is why the same intervention supports male hormonal health and can enlarge the prostate. And the clinical data shows both arms at once: in 183 men over 50 with BPH, testosterone was significantly lower in patients with severe LUTS (285.94 ng/dL) than mild (544.09 ng/dL) - so low testosterone tracks with worse urinary symptoms, while DHT drives the gland. That is not a contradiction to resolve, it is two different molecules. Bidirectionality is explicit: the relationship between hypogonadism and metabolic disorders is bidirectional, and a vicious circle between the two components has been documented. PMC6669361
