Faster Fertilization and Cleavage Kinetics Reflect Competence to Achieve a Live Birth: Data from Single-Embryo Transfer Cycles

Table 1

Fertilization and cleavage morphokinetic parameters of all embryos produced.

Parameter	Total ()	LB ()	NLB ()	value
tPNf (hrs.)
t2 (hrs.)
t3 (hrs.)
t4 (hrs.)
t5 (hrs.)
t8 (hrs.)

hrs.: hours; LB: live birth achieved; NLB: live birth not achieved; tPNf: time of pronuclear fading.
