Selection of competent blastocysts for transfer by combining time-lapse monitoring and array CGH testing for patients undergoing preimplantation genetic screening: a prospective study with sibling oocytes

Table 6 Comparison of clinical pregnancy and implantation rates between euploid blastocysts with tIB < 96.1 hpi and euploid blastocysts with tIB ≥ 96.1 hpi in Group A

Parameters	tIB < 96.1 hpi	tIB ≥ 96.1 hpi	pvalue
Patient with SET	12	7
Patient with DET	15	11
Clinical pregnancies after SET	8	3
Clinical pregnancies after DET	13	8
Clinical pregnancy rate	77.8%	61.1%	0.383^a
Implantation rate	71.4%	58.6%	0.386^a

tIB = time from insemination to initiation of blastulation; hpi = hours post insemination; SET = single embryo transfer; DET = double embryo transfer; ^aGroup A vs. Group B, by Chi-square analysis.
