How are FUT2 and Wechseljahre related?

The relationship between FUT2 and menopause (Wechseljahre) is not directly established in the scientific literature, but plausible mechanistic links exist. FUT2 determines secretor status (whether ABO antigens are secreted into body fluids) and influences gut microbiome composition. During menopause, declining estrogen levels alter the gut microbiome, which can affect inflammation, metabolism, and immune function. Some research suggests that secretor status may influence susceptibility to urinary tract infections or vaginal dysbiosis – conditions that become more relevant during menopause. However, no specific human studies directly connect FUT2 variants to menopausal symptoms, timing, or hormone-related outcomes. The evidence is therefore mechanistic and speculative. Consumers should not make personalized health decisions regarding menopause based solely on FUT2 genetics. Further research is needed to clarify any potential role.
