Adult rat Leydig cells, purified by Percoll density gradient centrifugation, were used to determine the effect of retinol and retinoic acid on steroidogenesis. It was found that both retinoic acid and retinol stimulated testosterone production. Although retinol was less potent than retinoic acid, retinol had the greater efficacy. When these retinoids were tested in the presence of a maximal dose of LH, it was found that retinol inhibited LH-stimulated testosterone synthesis whereas retinoic acid had no similar effect. These results demonstrate for the first time that retinol and retinoic acid have a direct effect on Leydig cell steroidogenesis in culture suggesting that retinoids play a role in the maintenance and regulation of Leydig cell function.
