What is the required step suggested by systematic reviews for definitively establishing onion's precise impact on human sperm count?

Answer

Further confirmatory clinical trials in humans

While the evidence derived from mechanistic studies using human sperm in vitro and extensive data from animal models is highly compelling regarding onion's benefits—especially concerning testosterone enhancement and significant protection against oxidative damage that impairs sperm quality—a definitive conclusion regarding the exact increase in human sperm count attributable solely to onion consumption remains pending. The overarching consensus reached by systematic reviews highlights that, despite the strong mechanistic backing, the transition to conclusive proof requires more rigorous investigation. Therefore, the crucial next step identified for solidifying these findings is the necessity of conducting further confirmatory clinical trials directly involving human subjects.
