Fig. 3From: Does the sex ratio of singleton births after frozen single blastocyst transfer differ in relation to blastocyst development?Sex ratio among singleton births following single blastocyst frozen embryo transfer (FET) cycles by different grades of trophectoderm (TE) and inner cell mass (ICM). Note: Sex ratio adjusted for age, BMI, type of fertilization, day of embryo transfer. P < 0.05 was considered statistically significant. CI = confidence interval; TE = trophectoderm; ICM = inner cell massBack to article page
