In a Japanese study conducted in 2011, researchers found that after administering Vitamin K2 MK4 to rats for a period of five weeks that "MK-4 stimulates testosterone production in rats and testis-derived tumor cells via activation of PKA. MK-4 (Vitamin K2) may be involved in steroidogenesis in the testis, and its supplementation could reverse the downregulation of testosterone production in elders (Study)."
