Evidence check: Hormoncheck Männer in the context of Fruchtbarkeit

The query concerns a hormone check for men in the context of fertility. Clinically established parameters such as testosterone, LH, FSH, prolactin, and estradiol are relevant for evaluating male infertility, especially in cases of oligo- or azoospermia. The evidence for these classic hormone measurements is strong (guidelines, endocrinology). However, the term 'Hormoncheck Männer' is often associated with direct-to-consumer (DTC) tests offered without medical interpretation. Such tests frequently measure only total testosterone, not free testosterone or SHBG, and ignore circadian rhythm and methodological limitations (e.g., immunoassay vs. LC-MS/MS). Their predictive value for fertility is limited without clinical context. Moreover, many offered markers (e.g., DHEA, cortisol) lack robust evidence for a direct link to male fertility. An evidence-based hormone check should always be performed by a specialist (andrology/urology) who interprets results in conjunction with semen analysis, clinical history, and lifestyle factors. The evidence for DTC hormone tests is rated as 'mixed': the underlying biomarkers are validated, but their use as a standalone fertility test without medical guidance is insufficiently supported.
