Fig. 2From: A case of discrepancy between three ERA tests in a woman with repeated implantation failure complicated by chronic endometritisPhotograph of blastocysts with successful pregnancies. a In the window of implantation as 113 ± 3 h after progesterone exposure, a vitrified-warmed blastocyst graded to 4 AA was transferred, resulting in a successful pregnancy and delivery. b One year after the first delivery, another vitrified-warmed blastocyst graded to 4 AA was transferred with the same window of implantation, resulting in a second successful pregnancy and delivery. Photographs of the two blastocysts were taken using a digital camera (BU130, Toshiba Teli, Tokyo, Japan) with a Nikon microscope (Nikon, Tokyo, Japan) and 10× objective lens. The captured images were edited using image management software (Phototune, CCM-BIS viewer soft, ASTEC, Fukuoka, Japan). The white bar in each photo indicates 100 μmBack to article page
