Pronuclear morphology and chromosomal abnormalities as scoring criteria for embryo selection  Luca Gianaroli, MD, M.Cristina Magli, MSc, Anna P Ferraretti, MD, PhD, Daniela Fortini, BSc, Natascia Grieco, BSc  Fertility and Sterility  Volume 80, Issue 2, Pages 341-349 (August 2003) DOI: 10.1016/S0015-0282(03)00596-X

FIGURE 1 Diagram showing the different configurations that identify pronuclear morphology, nucleolar morphology, and polar body alignment with respect to the longitudinal axis of pronuclei. Each configuration is conventionally given a capital letter in the case of pronuclear morphology (A–E), a number for nucleolar morphology (1–4), and a symbol from the Greek alphabet (α–γ) to identify the polar body alignment.

FIGURE 2 Percentage of embryos with a normal chromosomal complement (diamond), monosomies or trisomies (square), complex abnormalities (triangle) in relation to the configurations of pronuclear zygote morphology. Values with the same letter are statistically different. aP<.005, bP<.025; cP <.0001 represents the percentage of chromosomally normal embryos in A1α, A2β, A3β, and A3α vs. all the other configurations; dP<.0001 represents the percentage of embryos with complex abnormalities in A4α and A4β vs. all the other configurations.

FIGURE 3 Development to morulas according to the different configurations of pronuclear zygote morphology. aP<.0001 represents the percentage of morulas at 88 hours after insemination in A1α, A2β, and A3β vs. all the other configurations.
