Overview
Since the 1970s, behavioural ecologists and evolutionary biologists have been fascinated by the biological implications of sperm from different males competing for fertilization of the egg in the female reproductive tract. But until Human Sperm Competition there had never been a discussion of the phenomenon for the human species in book form, despite its relevance for a full understanding of human reproduction.
The book is a pioneering analysis of the evolutionary biology of human sexuality, proposing that all aspects have been shaped by the phenomenon of sperm competition. Written 20 years ago in 1993-94, the print edition was published in 1995. Despite its age that book's contents are as relevant now as they were two decades ago. Perhaps even more so, because since Baker and Bellis' demonstration that human sperm competition could actually be studied in a variety of ways a number of research groups have taken up the challenge where they left off. Most of these groups have obtained results that build firmly upon Baker and Bellis' original work. A few others created important dialogues. None though have destroyed any crucial part of the foundation first laid down in that 1995 book. But the main way in which Human Sperm Competition remains relevant to this day is that for various reasons - some cultural, some procedural, and yet others due to sheer opportunity - Baker and Bellis were able to do a number of experiments that others since have not had the opportunity to repeat. And the results of those unique experiments were presented in Human Sperm Competition and nowhere else.
In the first half of the book the authors explore the role of sperm competition in the evolution of human sexual characteristics, considering for example the architecture of the female reproductive tract, the reasons for male and female infidelity and the possible biological reasons for homosexuality, masturbation and orgasm.
In the second half, the mechanism of sperm competition is evaluated in detail, together with the evidence for and the implications of the authors' own Kamikaze Sperm Hypothesis. Human Sperm Competition sets out the thesis that adopting an evolutionary approach to human reproduction exposes the subtle and sophisticated ways in which human sexual anatomy, physiology and behaviour are designed to interact. As a species, understanding this sexual legacy helps explain how we reproduce today and why problems with fertility arise.
Over the years, Human Sperm Competition has become a classic in the study of human sexual biology - but although the original hardback is still in print rising costs plus perhaps its classic status have priced it beyond those students who might most wish to read its contents. This digital edition of the original 1995 publication, but at a student-friendly price, now solves this problem.

About the Author
Robin Baker: After obtaining a First Class Honours degree in Zoology (1965), then a PhD, at the University of Bristol (1968), Robin Baker lectured in Zoology for over 25 years at the Universities of first Newcastle-upon-Tyne and then Manchester. At Manchester he was Reader in Zoology in the School of Biological Sciences from 1981-1996. In 1996 he left academic life to concentrate on his career in writing and broadcasting. A best-selling author in the field of sexual biology, his books (6 academic, 4 popular science, and 3 novels) have been translated into 28 different languages. He has also published around 100 scientific papers and articles and his work and ideas on the evolution of human behaviour have been featured in many radio and television programmes around the world. Since 2002 he has lived in the foothills of the Spanish Sierras with his partner and their family. He has six children and three grandchildren.
Mark A. Bellis: After years working on the evolution of human behaviour, Mark turned his behavioural research to the improvement of population health. Since then he has led national and international research programmes to tackle alcohol and drug misuse, improve sexual health and prevent violence. He has published over 140 academic papers primarily on the relationships between human behaviour and health, and as Professor of Public Health at Liverpool John Moores University established and directed one of the UK's largest public health research departments. Professor Bellis is now Director of Policy, Research and Development for Public Health Wales; leading developments in public health nationally and working internationally with bodies including the World Health Organization and other arms of the United Nations. Mark is visiting Professor of Public Health at Liverpool John Moores University and holds honorary chairs in the Schools of Medicine at both Cardiff and Swansea Universities.
