Is Testosteron useful for Fruchtbarkeit?

Whether testosterone is useful for fertility depends on context. In men with clinically low testosterone, replacement therapy can improve libido but often suppresses natural sperm production, potentially worsening fertility. For men trying to conceive, alternatives like hCG or clomiphene are preferred. In women, testosterone is not routinely used for fertility; elevated testosterone (as in PCOS) is actually linked to reduced fertility. The provided context does not contain specific evidence on testosterone and fertility. Therefore, this answer is based on general medical knowledge (evidence level: human-moderate). Caveat: self-administered testosterone can cause infertility in men and should only be used under medical supervision.
