A common myth is that the 'warrior' variant (Val158Met) directly predicts fertility – for example, by conferring better stress handling or hormone balance. In reality, studies show only a small, inconsistent link: some research suggests a modest effect on estrogen metabolism, possibly relevant in conditions like endometriosis, but the effect size is tiny (about 1–2% of variance). The 'warrior'/'victim' labels are marketing hype, not clinical tools. For individual fertility, age, hormone levels, lifestyle, and organic causes are far more important. A COMT test alone cannot predict conception chances or IVF success. If considering supplements (e.g., magnesium, B vitamins) based on genotype, consult a doctor – there is no robust evidence for routine adjustments.

COMT degrades catecholamines and estrogens; the slower Met variant may lead to higher estradiol levels, which could theoretically affect fertility. Studies show associations with endometriosis risk (Met allele increases risk in some populations) and IVF outcomes, but effect sizes are small and population-dependent. A direct causal effect on natural fertility is not established. Moreover, COMT is often analyzed in combination with other genes (MTHFR, GST), complicating interpretation. Bottom line: A COMT test alone has no clinical predictive value for fertility. Lifestyle factors (stress, diet, smoking) dominate. Supplements like magnesium or green tea extract are sometimes marketed, but there is insufficient evidence for targeted COMT-based supplementation to improve fertility.
