Can CYP1A2 help with Fruchtbarkeit?

The provided context contains no direct evidence linking CYP1A2 to fertility. The only relevant SNP (rs762551) is discussed in relation to caffeine metabolism, with a tiny effect size (beta 0.01%) that is not clinically meaningful. While CYP1A2 is involved in estrogen metabolism, which could theoretically affect fertility, the given data does not support this. Evidence is therefore classified as unclear. Consumer genetic tests often overstate predictive power. For fertility concerns, clinical assessments (hormone levels, cycle tracking) and medical guidance are essential, not isolated gene variants.
