Background: Royal jelly (RJ) is a production from the hypo pharyngeal, mandibular and post cerebral glands of nurse bees. RJ consists of 66% water, 15% sugars, 5% lipids, and 13% proteins, essential amino acids and vitamins. The aim of this study was determination of effects of royal jelly on reproductive parameters.Methods: The aim of this study was to review the available studies on the role of Royal jelly on improving reproductive parameters in rat. For this purpose, the articles in databases Pub med and Google scholar in connection with the evaluation of the relationship between Royal jelly and fertility in male rat were searched.Result: A number of studies show a significant association between Royal jelly and improvement of reproductive parameters, especially, sperm count, sperm viability and motility and a number of studies expressed that the thickness of tunica albuginea (TAT) was increased significantly in the process.Conclusion: Royal jelly improved reproductive parameters such as testicular weight, sperm count, viability, motility, deformity, DNA integrity, chromatin quality, serum testosterone and testicular tissue MDA levels in rats.
