What role does Pharmakogenetik Medicheck play in Fruchtbarkeit?

Pharmacogenetics (PGx) examines how genetic variants affect drug metabolism and response. A PGx test like 'Medicheck' could theoretically assist fertility treatments by optimizing dosing or choice of hormonal drugs (e.g., clomiphene, letrozole, gonadotropins). However, clinical evidence for most such applications is weak. While known variants (e.g., in CYP2D6, CYP2C19, COMT) influence the breakdown of estrogens or other agents, randomized trials demonstrating clear fertility benefit are largely lacking. Fertility is multifactorial – hormone status, age, lifestyle, and organic causes dominate. A PGx test can provide only a small, mechanistic hint, not a diagnosis or guarantee. Caveat: Do not base fertility treatment decisions solely on a genetic test; always consult a specialist. Evidence grade: mechanistic/mixed.
