Menaquinone-4 enhances testosterone production in rats and testis-derived tumor cells

Conclusions: MK-4 stimulates testosterone production in rats and testis-derived tumor cells via activation of PKA. MK-4 may be involved in steroidogenesis in the testis, and its supplementation could reverse the downregulation of testosterone production in elders.
