The expression of AMH mRNA in the fresh, control, 0.5 mmol/L S1P, and 2 mmol/L S1P groups 10 days after transplantation. The AMH levels were significantly higher in the S1P-pretreated groups than in the nonprotective vitrified group. Reduced AMH levels were noted in the S1P groups compared with the fresh group, but those of the low- and high-concentration S1P groups did not differ statistically significantly. The data are expressed as mean ± standard error of the mean. ***P < .001. AMH indicates anti-Müllerian hormone; mRNA, messenger RNA; S1P, sphingosine-1-phosphate.
