Overall, the evidence for home testosterone tests in a fertility context is 'mixed': - Testosterone follows a strong diurnal rhythm (highest in the morning) and varies day-to-day. A single home saliva or blood test can be misleading. - Fertility assessment typically requires a panel of hormones (LH, FSH, prolactin, SHBG, free testosterone). A standalone testosterone test is insufficient. - Certified labs (e.g., ISO) can provide orienting values if sampling is correct (morning, fasting), but medical follow-up remains essential. - Genetic factors (e.g., androgen receptor polymorphisms) influence testosterone action but are usually not included in standard home tests.
