Download or read book Future Aspects in Human In Vitro Fertilization written by Wilfried Feichtinger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the organization of an international congress on in vitro fertilization (IVF) was an entirely new venture for us in 1983, since we had no experience but were full of optimism, we approached the organization of a second Congress in Vien na in 1986 much more calmly. Our experience had increased as had the readiness of many of our friends to help and of people interested in cooperating. However, would our Congress not lose its originality on account of the increased routine? This was certainly a possible danger which we wanted to prevent by means of two counter measures. The first concerned the scientific program: the new and trend-setting aspects of IVF would be discussed primarily rather than the results of traditional methods. The second measure concerned the social program, aimed more at private contacts in the intimate and familiar atmosphere of homes and workplace rather than meetings in luxurious but impersonal public institu tions. We believe that both these measures achieved the desired effect. Although we could not avoid some events taking place at the same time, the most important problems were treated and discussed jointly. Thus, the Congress was easy to survey, and all topics were thoroughly discussed.
Download or read book Sex Determination Differentiation and Intersexuality in Placental Mammals written by R. H. F. Hunter and published by Cambridge University Press. This book was released on 1995-03-09 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do males become male and females become female? And what are the consequences if the decision is not incisive? Drawing upon interests in animal genetics and molecular biology, the author endeavours to answer these difficult yet fascinating questions. Originally published in 1995, this book describes the genetic determination of sex and examines how sexual organs are differentiated. Using examples of intersexuality, chimaeras and asymmetries, the book describes the underlying molecular basis of sex determination and sexual differentiation, and focuses on the critical role of the rate of embryonic development in these vital processes. Male precocity is a recurrent theme, as is the involvement of Sertoli cells and their secretion of anti-Müllerian hormone. An invaluable book for reproductive physiologists, geneticists and developmental biologists whose interests may extend from animal science through veterinary medicine to human clinical medicine.

Available in PDF, EPUB and Kindle. Book excerpt: J. Warren Evans Department of Animal Science Texas A&M University College Station, Texas 77843 In the near future, improvement of domestic animals for the production of food and fiber is poised to undergo a revolution by the utilization of recent breakthroughs and advances in molecular genetics, embryo manipula tions, and gene transfer systems. Utilization of these techniques will have a wide impact on animal agriculture by improvement of production effi ciency via manipulation and control of many physiological systems. The end result will be to decrease production costs, increase food production and quality, and lower food costs. Health and well being of domestic and other animals will be improved as a result of new methods of disease diagnosis, vaccine production, and disease prevention practices. Genetic engineering also offers the possibility of utilizing animals for the development of pharmaceutical products to benefit society. Research progress will be en hanced via manipulation of the gene pool. The objectives of this Conference were to discuss the current status of animal bioengineering and to realistically assess the potential applica tions of current and future genetic technologies for the production of food and fiber to meet the needs of our hungry world, and to provide animal sci entists who may wish to utilize bioengineering in current or future re search programs with current background information regarding concepts, ap plications, and methodologies.

Download or read book Reproduction in Mammals written by Virginia Hayssen and published by JHU Press. This book was released on 2017-10-27 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating look at the diverse reproductive strategies of numerous female mammals, from hyenas to goats, kangaroos to whales. Newborn mammals can weigh as little as a dime or as much as a motorcycle. Some receive milk for only a few days, whereas others nurse for years. Humans typically have only one baby at a time following nine months of pregnancy, but other mammals have twenty or more young after only a few weeks in utero. What causes this incredible reproductive diversity? In Reproduction in Mammals, Virginia Hayssen and Teri J. Orr present readers with a fascinating examination of the varied reproductive strategies of a broad spectrum of mammals, from marsupials to whales. This unique book's comprehensive coverage gathers stories from many taxa into a single, cohesive perspective that centers on the reproductive lives of females. The authors shed light on a number of intriguing questions, including • do bigger moms have bigger babies? • do primates have longer pregnancies than other groups? • does habitat influence animals' reproductive patterns? • do carnivores typically produce larger litters than prey species? The book opens with the authors' definition of what constitutes a female perspective and an examination of the evolution of reproduction in mammals. It then outlines the typical individual mammalian female: her genetics, anatomy, and physiology. Taking a nuanced approach, Hayssen and Orr describe the female reproductive cycle and explore female mammals' interactions with males and offspring. Readers will come away from this thought-provoking book with an understanding of not only how reproduction fits into the lives of female mammals but also how biology has affected the enormously diverse reproductive patterns of the phenotypes we observe today.
