Abstract
Administration of 2 ml/day/animal, of melatonin-free pineal extract to the rat for three days induced a significant decrease in the testicular tissue concentration of testosterone, cholesterol and ascorbic acid. A dose of 1 microgram melatonin/day/animal given for 3 days did not alter these biochemical elements implied in testicular steroidogenesis.
