What
moves it.

These biological pathways influence Luteinizing Hormone. Click any to see what affects it.

emerging
GnRH/LH
GnRH → LH Signaling

Hypothalamus releases GnRH → pituitary releases LH → Leydig cells produce testosterone.

Leydig Cells
Leydig Cell Function

Leydig cells are the testosterone factories in the testes.

What
affects it.

botanical
Cistanche tubulosa

Raised LH and testosterone in rodent studies via GnRH signaling. No human testosterone RCT.

emerging$$
botanical
Eurycoma longifolia (Tongkat Ali)

Human RCTs show testosterone increase in hypogonadal men [citation:37]. Aromatase inhibition shown in vitro.

supported$$
adaptogen
Ashwagandha (Withania somnifera)

Reduces cortisol in multiple RCTs. May improve testosterone and stress resilience.

supported$$
botanical
Fenugreek

Contains 4-hydroxyisoleucine, which stimulates insulin release. Studied for testosterone and creatine uptake.

supported$$
botanical
Shilajit (PrimaVie)

Fulvic acid mineral complex. Possibly effective for testosterone in hypogonadal men [citation:31].

supported$$$
mineral
Zinc

Essential for testosterone synthesis. Supplementation helps only if deficient.

established$
vitamin
Vitamin D3 (Cholecalciferol)

Hormone-like vitamin. VDR receptors present in Leydig cells. Supplementation matters mainly in deficiency.
