To evaluate the effect of melatonin on in vitro maturation of goat oocytes, 12 females were used asoocyte donor. They were subjected to ovarian stimulation and ovum pickup by laparotomy. Oocytes wereevaluated and allocated into three groups of in vitro maturation: M0 (oocytes matured in TCM199 andsupplements); M10 and M50 (oocytes matured in M0 medium supplemented with 10 μM and 50 μM melatonin,respectively). All groups were subjected to the cell incubator for 24 hours at 38.5°C with a humidifiedatmosphere containing 5% CO2. For data analysis, Chi-square test was used, with a probability of 5% and acorrelation test. In conclusion, melatonin reduced in vitro maturation rates of goat oocytes.(AU)
