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 7 List of patients with pregnancy loss in time-lapse system (TL), conventional incubator (CI) and mixed transfer (MIX) groups

Patient’s ID	Age (years)	Clinical indication	Culture group	Pregnancy loss	Cytogenetic analysis	Array CGH result
1	39	URPL	CI	Singleton	Unknown	Euploid
2	38	RIF	CI	Singleton	46XY	Euploid
3	39	URPL	TL	Singleton	46XX	Euploid
4	38	URPL	MIX	Singleton	46XY	Euploid
5	37	PAC	MIX	Twin	47XX + 16, 45X0/46XX	Euploid

URPL = unexplained recurrent pregnancy loss; RIF = repeated implantation failure; PAC = previous aneuploid conception; CI = conventional incubator; TL = time-lapse system; MIX = mixed embryo transfer (one embryo from the time-lapse system and another one from the conventional incubator).
