Hatching out from the zona pellucida (ZP) is a crucial step for blastocyst implantation and development. However, it is still unknown whether the location of the hatching site relative to the inner cell mass (ICM) affects embryo implantation and foetal development. Here, we classified hatching blastocysts into three categories, 0° ≤ θ ≤ 30°, 30°  less then  θ ≤ 60°, and 60°  less then  θ ≤ 90°, in which θ is determined based on the relative position of the hatching site to the arc midpoint of the ICM.
