Histological sections of cold-shocked eggs after fertilization. A (70 min after fertilization: af): second polar body released and egg nucleus present just underneath the polar body; B (70 min af) second polar body present, but no egg nucleus; C (70 min af): abnormal extrusion of second polar body (note abnormal metaphase equator or nuclear substances ranging from egg surface to polar body); D (70 min af): extrusion of second polar body suppressed; E (70 min af): condensed sperm nucleus present; F (80 min af): decondensed male pronucleus appears; G (90 min af): two asters seen; H (100 min af): anaphase of first cleavage. Scale bars denote 10 μm.
