How are Testosteron and Fruchtbarkeit related?

Testosterone is a key hormone for male fertility, as it drives sperm production in the testes. Low levels can lead to oligospermia or azoospermia. In women, elevated testosterone may indicate polycystic ovary syndrome (PCOS), which impairs fertility. The relationship is well-established and sex-specific. MyBody-X DNA tests do not directly assess testosterone or fertility genes; they focus on metabolism and diet. Variants in genes like SHBG or AR can influence testosterone levels, but these are not in the standard panel. Evidence is based on clinical research, not the provided context. Caveat: hormone levels should be measured by a doctor, not inferred from genetic tests.
