A retrospective cohort study conducted in 138 patients undergoing their first preimplantation genetic screening (PGS) cycle between January 1, 2006, and December 31, 2007, demonstrated that embryos with good day-3 morphology were more likely to be euploid for X/Y, 8, 15, and 18 than those with poor morphology. The strength of association between euploidy and day-3 morphology was not influenced by maternal age.
一项回顾性队列研究纳入了 138 例于 2006 年 1 月 1 日至 2007 年 12 月 31 日期间进行首次胚胎植入前遗传学筛查（PGS）周期的患者，结果显示，与形态学较差的胚胎相比，形态学良好的胚胎更有可能具有 X/Y、8、15 和 18 号染色体的整倍体性。整倍体性与第 3 天形态之间的关联强度不受母体年龄的影响。
