Objectives:To analyze the association between fetal sexchromosome abnormalities and various high-risk indications during pregnancy. Methods:mid-trimester amniocentesis was used to detect fetal sex chromosomes in 2 346 high-risk pregnant women. Results:Among the 16 cases of abnormal sex chromosome
there were 3 cases of 45

inv9(X). Conclusion:To reduce the number of abnormal fetuses
invasive prenatal diagnostic techniques are feasible tools for confirming fetal sex chromosomes abnormalities. Advanced maternal age
positive serum screening results or ultrasound shows fetal abnormalities or fetal hygroma were associated with a higher frequency of fetal sex chromosome abnormalities.
