Some interest has been generated in studying the rationale for assisted hatching. some reports suggest that embryos with lower zona pellucida thickness ( zpt ) and higher zona pellucida thickness variation ( zptv ) had a better chance of successful hatching and so the patient become pregnant ; another reports suggest that in vivo aging ; in vitro culture and exposure to ultralow temperature may induce zona hardening and then impair the embryo ability of hatching
有作者提出胚胎透明帶厚度（ zonapellucidathickness ， zpt ）小的胚胎孵出時阻力減小，而透明帶厚度變化率（ zonapellucidathicknessvariation ， zptv ）高的胚胎由於透明帶上有一個明顯薄的區域而使胚胎易於孵出；還有作者推測病人年齡、體外培養天數的增加及冷凍處理會增加透明帶的硬度，使胚胎孵出困難。
