This book was released on 2013-04-17 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigations into the mechanisms of spennatogenesis, sperm matura tion and fertilization provide the basis of our understanding of male re productive physiology. Since in recent years molecular and cellular en docrinology has provided particularly important contributions to our knowledge, the European Workshops on Molecular and Celluar Endo crinology of the Testis, held regularly during even years since 1980, have become a prominent forum for researchers in the field to discuss recent findings and exchange new ideas. The most recent of these Testis Workshops, the 7th, was held on May 5 - 10, 1992 at Castle Elmau in the Bavarian Alps. The main lectures of this Workshops form the core of this book. In order to provide a broader view of the current status of male re production research, this volume also contains the proceedings of the Schering Foundation Workshop on "Basic Mechanisms of Reproduc tion and Male Fertility Control" which was held in Berlin on October 31 to November 2, 1991. The topics of the two meetings were planned to complement each other. By combining the proceedings of both workshops, it became possible to produce a book that covers a wide spectrum of current highlights in male reproduction research and pro vides the reader with an up-to-date review of the field. The timeliness of the book is emphasized by the fact that it was al ready available when the 7th European Testis Workshop took place.

This book was released on 1996-11-04 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "contraceptive revolution" of the 1960s and 1970s introduced totally new contraceptive options and launched an era of research and product development. Yet by the late 1980s, conditions had changed and improvements in contraceptive products, while very important in relation to improved oral contraceptives, IUDs, implants, and injectables, had become primarily incremental. Is it time for a second contraceptive revolution and how might it happen? Contraceptive Research and Development explores the frontiers of science where the contraceptives of the future are likely to be found and lays out criteria for deciding where to make the next R&D investments. The book comprehensively examines today's contraceptive needs, identifies "niches" in those needs that seem most readily translatable into market terms, and scrutinizes issues that shape the market: method side effects and contraceptive failure, the challenge of HIV/AIDS and other sexually transmitted diseases, and the implications of the "women's agenda." Contraceptive Research and Development analyzes the response of the pharmaceutical industry to current dynamics in regulation, liability, public opinion, and the economics of the health sector and offers an integrated set of recommendations for public- and private-sector action to meet a whole new generation of demand.

Download or read book The Control of Fertility written by Gregory Pincus and published by Elsevier. This book was released on 2013-09-03 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Control of Fertility is concerned with the experimental control of fertility as a specific biological problem. It is, first of all, an attempt to summarize a collection of data hitherto either partially or not at all presented. Secondly, it attempts to indicate those avenues which hold promise for future investigation. Finally, it attempts an assessment of the implications of understandings and ignorances. The book opens with an account of the sequence of processes essential to successful sexual reproduction in mammals. This is followed by separate chapters on approaches to the inhibition of spermatogenesis, ovulation, fertilization, and free ovum development. Subsequent chapters deal with blastocyst development and implantation, biological activities of compounds affecting fertility, fertility control in men and women, the inhibition of ovulation, biological properties of ovulation inhibitors in human subjects, and effectiveness and acceptability of contraception.

This book was released on 2013-03-09 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contraceptive research has entered the new age of vaccines. Realistic prospects exist for the development of an entirely new battery of vaccines for use in human and veterinary medicine. Among them may be anti-fertility vaccines, based on physiological mechanisms applicable to either the female or male. This volume is a comprehensive review - a status report - of the subjects including fundamental work on the search for useful epitopes and ranging to applied vaccinology. One vaccine to prevent pregnancy, for use by women, has already been studied extensively. G.P. Talwar, the volume's editor and his colleagues in New Oelhi, India, published in 1976 a landmark series of papers describing the immunological properties of a preparation consisting of the alum-precipitated beta-subunit of human chorionic gonadotropin (hCG) chemically linked to tetanus toxoid. The principle of enhancing antigenicity of a self-protein by linkage of the epitope to a carrier protein was employed and tested clinically. These trials, carried out under the auspices of the Indian Council for Medical Research, were the first application of the carrier protein concept for a vaccine for human use. The encouraging results stimulated a wave of research not only on the use of hCG-based vaccines, but on other antigens as well.

Available in PDF, EPUB and Kindle. Book excerpt: The world’s population is growing at an unsustainable rate. From a baseline ?gure of one billion in 1800, global population is predicted to exceed nine billion by 2050 and 87. 8% of this growth will be localized in less developed countries. Such uneven population growth will yield a harvest of poverty, malnutrition, disease and en- ronmental degradation that will affect us all. Amongst the complex mixture of political, social, cultural and technological changes needed to address this issue, the development of improved methods of fertility regulation will be critical. The inadequacy of current contraceptive technologies is indicated by recent data s- gesting that the contraceptive needs of over 120 million couples go unmet every year. As a direct consequence of this de?cit 38% of pregnancies are unplanned and more than 50% end in an abortion, generating a total of 46 million abortions per annum particularly among teenagers. If safe, effective contraceptives were ava- able to every couple experiencing an unmet family planning need, 1. 5 million lives would be saved each year (UNFPA 2003). Progress in contraceptive technology should not only generate more effective methods of regulating fertility, but should also provide a range of methods to meet the changing needs of the world’s population. Contraceptive practice was revo- tionized in 1960 in the US and 1961 in Europe by the introduction of the oral contraceptive pill by Gregory Pincus, MC Chang and colleagues, based on fun- mental hormone research conducted in Germany.

Download or read book Gossypol written by Sheldon J. Segal and published by Springer. This book was released on 1985 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for a reversible male contraceptive has centered upon the suppression of sperm production or sperm motility. Gossypol, a natural substance extracted from the cotton plant, appears to cause both of these effects. Its ability to reduce spermatogenesis in men is undeniable and has been demonstrated in both large studies in China and a smaller confirmatory study in Brazil. These investiga tions have revealed the remarkable fact that with gossypol, it is possible to separate an effect on the testis' gamete-producing function from an effect on its hormone-producing function. Thus, it is possible to maintain normal testosterone levels and libido while sperm counts (and motility) fall. Because of this unique and important action, gossypol warrants the fullest possible evaluation as a potential male contraceptive. Sheldon J. Segal vii ACKNOWLEDGMENT Lynn C. Landman played a major role in this publication by skillfully editing the manuscripts which were submitted for inclusion in this volume. Janet O'Connell added her efforts in editing, assembling texts and figures and handling final details required for publication. I thank these talented colleagues for their invaluable contributions.

Download or read book Infertility in the Male written by Larry I. Lipshultz and published by Cambridge University Press. This book was released on 2009-09-24 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of this canonical text on male reproductive medicine will cement the book's market-leading position. Practitioners across many specialties - including urologists, gynecologists, reproductive endocrinologists, medical endocrinologists and many in internal medicine and family practice – will see men with suboptimal fertility and reproductive problems. The book provides an excellent source of timely, well-considered information for those training in this young and rapidly evolving field. While several recent books provide targeted 'cookbooks' for those in a male reproductive laboratory, or quick reference for practising generalists, the modern, comprehensive reference providing both a background for male reproductive medicine as well as clinical practice information based on that foundation has been lacking until now. The book has been extensively revised with a particular focus on modern molecular medicine. Appropriate therapeutic interventions are highlighted throughout.

Download or read book A Textbook of Clinical Embryology written by Eliezer Girsh and published by Cambridge University Press. This book was released on 2021-05-06 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Personnel working in assisted reproductive technology often lack the opportunities for dedicated training in the specialized techniques and technologies required for the procedures. As such, success in the form of live birth rates can range from over 50% to less than 10% per treatment cycle. This comprehensive introductory textbook is an essential resource for trainee embryologists, medical students and nurses. The recent revolutions in biotechnology and molecular biology involved in delivering assisted reproductive services are thoroughly discussed. Basic knowledge such as the development and physiology of both male and female reproductive systems is covered, with practical aspects of IVF including gamete and embryo manipulation, cryopreservation and genetic testing explained in detail. A full description of the optimal structure and management of the IVF laboratory is given, helping ensure procedures are safe and effective. Extensive and highly detailed colour illustrations bring the content to life and aids readers in their understanding.
