Testicular Leydig cells are major contributors of androgen synthesis and secretion, which play an important role in testis development, normal masculinization, maintenance of spermatogenesis, and general male fertility. The rate-limiting step in testosterone biosynthesis involves the transfer of cholesterol to the mitochondrial inner membrane by the steroidogenic acute regulatory (Star) protein, a critical factor in steroid hormone biosynthesis. Once inside the mitochondria, cholesterol is metabolized by the steroidogenic enzyme Cyp11a1 to pregnenolone, which is further converted to testosterone by the action of other steroidogenic enzymes...
