The implantation sites on Days 5.5 and 7.5 of pregnancy. MT: melatonin group; C: control group; LE: light extended group; LE + MT: light extended group treated with melatonin (10−4 M). a Implantation sites on Day 5.5 (14. 8 ± 0.62, 14.0 ± 0.67, 11.2 ± 0.43 and 13.4 ± 0.48 in the MT, C, LE and LE + MT groups, respectively) and on Day 7.5 (12.0 ± 0.37, 11.7 ± 1.48, 10.0 ± 0.58 and 11.4 ± 0.40 in the MT, C, LE and LE + MT groups, respectively). b Representative images of uterine implantation sites on Day 5.5 (up) and Day 7.5 (down) of pregnancy. Data are expressed as the means ± SEM (N = 9). Different superscript letters indicate statistically significant differences (P < 0.05)
