Previously reported and here added cases demonstrate euploid pregnancies followed by PGT-A as “mosaic” as well as “aneuploid” designated embryos

Table 1 Characteristics of 2 “aneuploid” embryo transfers leading to normal pregnancy/delivery*

Patient	TEB result	Diagnostic platform	Transfer date	IVF cycle outcome	Chromosomal outcome
1	48, XX, + 14, −18	Microarray	6/10/2020	NSVD, 2/26/2021	46, XX
2	46, XY, del/dup 20; 45, XY, −21	Microarray	6/28/2021	NSVD, 3/14/2022	46, XY

*A 3rd pregnancy, transferred on 2/10/2020 with a single “aneuploid” embryo (47, XY, + 16), experienced a potentially preventable pregnancy loss shortly following an amniocentesis that demonstrated a normal 46, XY karyotype by microarray [5]
NSVD normal spontaneous vaginal delivery, EDC expected date of confinement
