Hormon & VitalCheck für Männer: which blood markers matter?

The question about which blood markers matter for a male hormone & vitality check cannot be specifically answered from the provided context – the snippets cover DNA tests, microbiome, and sports, not blood markers. From general medical practice, key markers include: total and free testosterone, SHBG, LH, FSH, estradiol, prolactin, vitamin D, vitamin B12, ferritin, TSH, and possibly cortisol and PSA. These assess hormonal balance, micronutrient status, and thyroid function. Evidence is based on endocrine guidelines and clinical practice, not on the given sources. Caveat: blood markers are not diagnostic; a physician should interpret results in context. MyBody-X offers such checks, but they are lifestyle tests, not medical devices. Results can serve as a screening tool but do not replace medical evaluation for symptoms like fatigue, low libido, or erectile dysfunction.
