                                According to a 1994 study using isolated rat Leydig cells, agents that increase phosphatidic acid inhibited LH-induced testosterone production. This has raised questions for some, but does phosphatidic acid reduce testosterone in humans when taken as a supplement? This article explores the current evidence, distinguishing between lab findings and real-world results.
