Melatonin concentrations throughout the study period. Day 0: controlled intravaginal drug release (CIDR) insertion; Day 6: CIDR substitution; Day 12: CIDR removal; Day 14: insemination; Day 20: embryo recovery. In two melatonin-treated groups, the melatonin levels dropped after CIDR removal; however, these levels were still significantly higher than those of the control (p < 0.05). The decreased melatonin levels rose again during the period between the insemination and embryo recovery. In the control group, the melatonin levels did not change among various stages. Values are given as the mean ± S.E.M. The error bar is extended above and below at each time point in the MT40 mg group and MT80 mg group, respectively. “*” or “#” mean p < 0.05.
