The Bob Edwards Lecture: The first cleavage division in human embryos – Professor Geraldine Hartshorne, University of Warwick and Centre for Reproductive Medicine, UHCW NHS Trust, UK

By the end of the lecture, the audience will know that:
• First mitosis is longer than subsequent mitoses.
• Problems at first cleavage are not female age-related.
• Different nuclear configurations in one or both cells at 2c stage are compatible with live birth.
• Eggs and embryos unsuitable for use in treatment can be informative in research with results similar to fresh eggs.
