How you
get there.

These biological pathways drive progress toward fertility.

supported
Leydig Cells
Leydig Cell Function

Leydig cells are the testosterone factories in the testes.

emerging
GnRH/LH
GnRH → LH Signaling

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

What
helps.

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.
