Can Pharmakogenetik Medicheck help with fertility?

Whether a pharmacogenetics (PGx) test like 'Medicheck' can help with fertility depends on context. PGx analyzes how genetic variants affect drug metabolism and response. In fertility treatment, this could theoretically guide dosing of hormones (e.g., clomiphene, FSH) or predict adverse reactions. However, the evidence is limited: most findings come from GWAS or mechanistic studies, not large randomized trials showing improved pregnancy rates. Fertility is multifactorial—age, lifestyle, hormonal balance, and anatomical factors often outweigh genetic influences. Commercial PGx tests for fertility often lack validation and may overstate benefits. A responsible approach: use PGx only as part of a comprehensive fertility workup under specialist supervision. The current evidence grade is 'mixed'—some plausible mechanisms exist, but clinical utility remains unproven. Patients should be cautious of marketing claims and prioritize evidence-based fertility care.
