Case 20. Close up of a trisomy 3 (47,XY,+3) IVF embryo. The GD2 embryo, 3 mm in length, showed no recognizable external structures after the amnion had been opened.

Case 13. Intact amniotic sac (A) containing a growth-disorganized IVF embryo 8 mm in length. The GD2 embryo is directly attached to the amnion. An apparently normal karyotype was diagnosed cytogenetically (46,XX).

Case 16. Close-up lateral (a) and anterolateral (b) view of a macerated trisomy 13 (47,XY,+13) embryo after the amniotic membrane (A) had been opened. External developmental defects of the 15-mm-long embryo resulting from IVF are severe microcephaly, fusion of the face to the chest, and retarded limb development. The dark brown areas in the thoracic region are due to maceration; umbilical cord (U).

5. FIGURE 4
Case 6. Lateral view of a macerated, microcephalic trisomy 14 (47,XX,+14) embryo. Upper (UL) and lower (LL) limbs of the 18-mm-long embryo resulting from IVF show hand and foot plate development. Digital rays are beginning to be apparent on the hands but are not notched, indicating retarded development for an embryo of this size. M marks the microforceps.
