GQE PQE  FC (+) (n = 13) 76.9% (10/13) 23.1% (3/13)  FC (-) (n = 21) 42.9% (9/21) 57.1% (12/21)

Table 1: Table 1: Comparison of embryo quality in oocytes with/without FC. GQE: good quality embryos, PQE: poor quality embryosOut of 34 oocytes in which we could observe the entire fertilization process and the SEP, 13 (38.2%) had a FC and the remainder showed no FC. Of 13 oocytes with FC, 10 (76.9%) developed into a good quality embryo (GQE), while only 9 of 21 oocytes without FC (42.9%) developed a GQE.
