The present study evaluated the effect of melatonin on the degree of embryonic quality during theprocess of in vitro production of embryos. 512 cumulus-oocyte complexes of type I and II were submitted to invitro production of embryos with 0 and 100 µM of melatonin in the maturation medium. There was no differencerelative to the rate of cleavage 36.44% vs 32.93% and total viable embryos 16.44% vs 12.16% (P <0.05).Likewise, there was no difference in the degree of embryonic quality (P <0.05). Therefore, the mediumsupplemented with melatonin was not able to improve the cleavage rate, total viable embryos and quality ofembryos fertilized in vitro.(AU)
