Compared to these thresholds, 24 patients were considered to have imprinting errors: 15 had imprinting errors on H19;7had errors on SNRPN, and 7had errors on KCNQ1OT1. To investigate whether ART outcomes were associated with sperm imprinting, the infertile males were subgrouped into normal (n = 69) and abnormal (n = 24) imprinting groups according to the thresholds mentioned above. Here, KCNQ1OT1 is linked to Infertility.
