This book provides a completely integrated approach to the study of mammalian reproduction, spanning the disciplines of anatomy, physiology, endocrinology, immunology, genetics and obstetrics and gynaecology. It draws out the general fundamental points common to reproduction in most mammalian species. However, it does not ignore the differences between species in some areas, often pointing these out in tabular form as an illustration for clarity of presentation. Where the fundamentals differ, an explicit discussion is given in the text. This new edition has been updated and revised to take account of the changing profile of hormones involved in reproduction, covering general principles of hormone action in the widest sense, including new data on growth factors. The new edition will also be in the large "essentials" format with a second colour throughout, and a substantial amount of completely new artwork.
