Effects of 10−9 M melatonin with or without selective MT2 antagonists (10−9 M luzindole or 10−9 M 4-P-PDOT) during IVM on subsequent embryo development after parthenogenetic activation. (A) Number of cultured embryos; (B) Cleavage rate; (C) Blastocyst rate; (D) Total cell numbers/blastocyst. A total of 639 oocytes was used in four independent replicates. Data are shown as the means ± SEM. Within each category, groups marked with different letters are significantly different (p < 0.05). Mtn, melatonin.
