What to watch with Hormoncheck Männer and fertility?

A male hormone check (e.g., testosterone, LH, FSH, prolactin, estradiol) can provide initial clues about potential fertility issues, but it is not a complete fertility test. Key caveats: Testosterone shows strong diurnal variation (highest in the morning) and should be measured under standardized conditions. A single low value does not predict sperm quality. LH and FSH reflect the hypothalamic-pituitary-gonadal axis; elevated FSH may indicate testicular dysfunction. However, most consumer hormone tests lack sperm analysis (count, motility, morphology), which is essential for fertility assessment. Genetic causes (e.g., Y‑chromosome microdeletions, Klinefelter syndrome) are also not covered. Evidence is mixed: a hormone check can serve as a screening tool but does not replace a full andrological workup. Beware of overinterpreting single values. For couples trying to conceive, a visit to a urologist/andrologist with a semen analysis and targeted hormone testing is necessary.
