(A) Monopronuclear (1PN) zygote, 16 to 20 hours after ICSI. (B) Blastocyst image from a 1PN ICSI zygote (D+5). (C) Fixation of 5th day blastocyst (magnification: ×10). In the smaller image, nuclei detail (magnification: ×20). (D) Same image processed by FISH showing to XY diploid constitution: two chromosomes 13 (red), two 18 (aqua), two 21 (green), one X (blue), and one Y (gold).
