How are Hormoncheck Frauen and fertility related?

The Hormoncheck Frauen by MyBody-X analyzes various hormone levels (e.g., estrogen, progesterone, testosterone) in saliva or blood. Hormonal imbalances can affect fertility, e.g., through cycle irregularities or reduced egg quality. However, evidence for such home tests is limited: hormone fluctuations are normal, and results should always be interpreted by a doctor in a clinical context. The test can provide clues but does not replace medical diagnostics. Many factors like stress, diet, or thyroid function also matter. Thus, the relevance for fertility is moderate to unclear.
