The Consequence of Short Insemination Strategy on Sperm Biological Characteristics, Embryo Morphokinetics, and Clinical Outcomes in the IVF Program

Table 2

Comparison of morphokinetics “individual” variables between two groups.

Time-lapse parameters	Short insemination (n = 247)	Long insemination (n = 278)	p-value
TPNF	24.44 ± 3.53	24.74 ± 5.06	0.44
t2	27.37 ± 4.34	27.66 ± 4.97	0.49
t3	36.94 ± 6.11	37.35 ± 6.2	0.46
t4	39 ± 6.32	39.66 ± 6.69	0.27
t5	48.85 ± 8.02	50.29 ± 7.36	0.04
t6	52.24 ± 6.98	52.65 ± 6.16	0.51
t7	53.76 ± 5.54	54.29 ± 5.59	0.37
t8	56.73 ± 5.63	57.02 ± 5.43	0.66

Results are presented as mean ± SD for normal numerical variables. TPNf, PN fading; t2, first cleavage (two-cell stage); t3, three-cell stage; t4, four-cell stage; t5, five-cell stage; t6, six-cell stage; t7, seven-cell stage; t8, eight-cell stage. p-value <0.05 was considered as statistically significant. Data were compared using independent-samples t-test.
