Can Longevity DNA Test help with fertility?

Whether a Longevity DNA test can help with fertility is not clearly supported by current evidence. The provided context contains no specific fertility markers. Fertility is multifactorial—age, hormones, lifestyle, environment, and medical conditions dominate. Some DNA tests analyze SNPs in genes like FSHB, ESR1, or MTHFR, but effect sizes are small and evidence is weak or conflicting. No single SNP can predict fertility issues or replace clinical evaluation. Clinical validation for such tests is largely lacking. Therefore, caution is warranted: a DNA test may offer only supplementary clues, not a diagnosis or treatment plan. For serious fertility concerns, professional medical advice is essential. The evidence level for this application is 'unclear' or 'marketing'.
