Can FUT2 help with Fruchtbarkeit?

The question of whether FUT2 can help with fertility is not clearly answered by current science. FUT2 encodes a fucosyltransferase that determines secretor status and influences the gut microbiome, vitamin B12 absorption, and possibly immune modulation. Some observational studies have linked certain FUT2 variants (e.g., rs601338) to altered risk of recurrent miscarriage or fertility-related conditions, but the evidence is weak and inconsistent. Most findings are mechanistic or from small cohorts; no large-scale clinical trials confirm a direct effect on fertility. The Fertility Check product you mentioned analyzes hormonal markers (AMH, estradiol, progesterone, FSH, prolactin) – it does not include FUT2 genotyping. A standalone DNA test for FUT2 cannot predict your current fertility status. For personalized fertility planning, consult a reproductive specialist and consider comprehensive clinical evaluation rather than isolated genetic markers.
