Review of the hardback: '... a pleasure to read because of Hunter's clear style ... a successful amalgamation of information from many mammalian species ... a concise and well-written summary of what is known and hypothesized about mammalian sex determination and differentiation ...' Science Review of the hardback: '... eminently suitable for the advanced students for whom it is intended and is a must for anyone involved in the field of mammalian sex differentiation.' Nature Review of the hardback: '... elegant and informative ... it fully deserves a place on the shelves of all university libraries and in departments and units with any interest in reproduction and development.' Journal of Anatomy Review of the hardback: '... a sound contribution to a fascinating, much debated, and currently widely investigated field ... a really exciting monograph.' Animal Reproduction Science ...provides a clear and factual account of the experimental evidence that has led to the present position, against a background of normal and abnormal sexual development....very readable....Hunter sets out the relevant facts and hypotheses in a perfectly detached manner, allowing readers to make up their own minds. The book is eminently suitable for the advanced students for whom it is intended, and is a must for their teachers, as well as for anyone involved in the field of mammalian sex differentiation. Ursula Mittwoch, Nature It is a pleasure to read because of Hunter's clear style and elegant exposition....I am pleased to have this concise and well-written summary of what is known and hypothesized about mammalian sex determination on my shelf as a reference. The index is excellent, and there are many important references up to 1994. Barbara R. Migeon, Science Based on the depth and sophistication of the subject matter, the book will be useful to graduate students and professionals in reproductive medicine, genetics and molecular and developmental biology. H.S. Pitkow, Choice The greatest strength of the book is the uniformity and enthusiasm provided by having a single author who is dedicated to his topic. Aline M.
