Download or read book Fertility Research Trends written by Grace Harris and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertility is the natural capability of giving life. As a measure, the "Fertility Rate" is the number of children born per couple, person or population. This is different to fecundity, which is defined as the potential for reproduction (influenced by gamete production, fertilisation and carrying a pregnancy to term). Human fertility depends on factors of nutrition, sexual behaviour, culture, instinct, endocrinology, timing, economics, way of life, and emotions. Animal fertility has no fewer complexities, and may display many interesting mechanisms. This book presents the latest research from around the world in this field.
Download or read book Recent Fertility Trends in Sub Saharan Africa written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-03-18 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertility rates and population growth influence economic development. The marked declines in fertility seen in some developing nations have been accompanied by slowing population growth, which in turn provided a window of opportunity for rapid economic growth. For many sub-Saharan African nations, this window has not yet opened because fertility rates have not declined as rapidly there as elsewhere. Fertility rates in many sub-Saharan African countries are high: the total rate for the region is estimated to be 5.1 births per woman, and rates that had begun to decline in many countries in the region have stalled. High rates of fertility in these countries are likely to contribute to continued rapid population growth: the United Nations projects that the region's population will increase by 1.2 billion by 2050, the highest growth among the regions for which there are projections. In June 2015, the Committee on Population organized a workshop to explore fertility trends and the factors that have influenced them. The workshop committee was asked to explore history and trends related to fertility, proximate determinants and other influences, the status and impact of family planning programs, and prospects for further reducing fertility rates. This study will help donors, researchers, and policy makers better understand the factors that may explain the slow pace of fertility decline in this region, and develop methods to improve family planning in sub-Saharan Africa.

Download or read book Low Fertility and Reproductive Health in East Asia written by Naohiro Ogawa and published by Springer. This book was released on 2014-10-07 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a unique blend of social and biomedical sciences in the field of low fertility and reproductive health. It offers a significant contribution to understanding the determinants of low fertility mostly in East Asia, including an assessment of the effectiveness of policies that aim to raise fertility. It introduces new analytical tools and methods and shares application of innovative approaches to analyzing cross-sectional and longitudinal survey data and macro socioeconomic data to shed light on changing mechanisms of low fertility in the context of reproductive health. The volume introduces the demographic dividend into the study of fertility, analyzes possible impact of population ageing on the amount of resources allocated to child rearing, i.e. the so called "crowding effect" in social care and public spending between the elderly and children. The book also tests the Low Fertility Trap (LFT) hypothesis, a new important theory regarding fertility trends. The book focuses on East Asia which is numerically large but relatively under-researched with regard to issues covered in various chapters. The relevance of the volume, however, goes beyond countries in East Asia. The book breaks new grounds and reveals little known facts regarding the influence of endocrine disruptors on male fertility through falling sperm counts, the phenomenon of marital sexlessness and about the sexual behavior of adolescents in East Asia.
Download or read book Ultra Low Fertility in Pacific Asia written by Paulin Straughan and published by Routledge. This book was released on 2008-09-25 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Japan, Singapore, Taiwan, South Korea and Hong Kong SAR are among the very lowest-fertility countries in the whole world, and even China has reached fertility levels lower than those in many European countries. If these levels continue over long periods East Asia will soon face accelerating population decline in addition the changes in age distributions in such populations raise major new questions for planning of economic and social welfare. This book brings together work by noted experts on the low fertility countries of East Asia with an up-to-date analysis of trends in fertility, what we know about their determinants and consequences, the policy issues and how these are being addressed in the various countries. Its role in bringing together information on policy trends and initiatives of a pro-natalist kind adopted over recent years in these countries is extremely important, as is the fact that the discussion of these pro-natalist policies is set in the context of a thorough analysis of what has driven fertility so low in these countries. Ultra-Low Fertility in Pacific Asia is invaluable to students and scholars of East Asian public and social policy, as well as fertility studies more generally.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides andrologists and other practitioners with reliable, up-to-date information on all aspects of male infertility and is designed to assist in the clinical management of patients. Clear guidance is offered on classification of infertility, sperm analysis interpretation and diagnosis. The full range of types and causes of male infertility are then discussed in depth. Particular attention is devoted to poorly understood conditions such as unexplained couple infertility and idiopathic male infertility, but the roles of diverse disorders, health and lifestyle factors and environmental pollution are also fully explored. Research considered stimulating for the reader is highlighted, reflecting the fascinating and controversial nature of the field. International treatment guidelines are presented and the role of diet and dietary supplements is discussed in view of their increasing importance. Clinicians will find that the book’s straightforward approach ensures that it can be easily and rapidly consulted.
Download or read book Low Fertility Institutions and their Policies written by Ronald R. Rindfuss and published by Springer. This book was released on 2016-06-16 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines ten economically advanced countries in Europe and Asia that have experienced different levels of fertility decline. It offers readers a cross-country perspective on the causes and consequences of low birth rates and the different policy responses to this worrying trend. The countries examined are not only diverse geographically, historically, and culturally, but also have different policies and institutions in place. They include six very-low-fertility countries (Austria, Czech Republic, Hungary, Italy, Spain, and Taiwan) and four that have close to replacement-level fertility (United Kingdom, Norway, Canada, and France). Although fertility has gone down in all these countries over the past 50 years, the chapters examine the institutional, policy, and cultural factors that have led some countries to have much lower fertility rates than others. In addition, the final chapter provides a cross-country comparison of individual perceptions about obs tacles to fertility, based on survey data, and government support for families. This broad overview, along with a general introduction, helps put the specific country papers in context. As birth rates continue to decline, there is increasing concern about the fate of social welfare systems, including healthcare and programs for the elderly. This book will help readers to better understand the root causes of such problems with its insightful discussion on how a country’s institutions, policies, and culture shape fertility trends and levels.

Download or read book Comparison of Fertility Trends Estimated Alternatively from Birth Histories and Own Children written by Robert D. Retherford and published by . This book was released on 1985 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertility trends estimated alternately from birth histories and own children method are compared for eight developing countries in which the World Fertility Survey was conducted. Principle hypotheses are that fertility trends estimated by the two approaches suffer from similar errors in the reporting of women's and children's ages, and that these errors are more severe in estimates derived from own children than in estimates derived from birth histories. The hypotheses are confirmed in four of the eight countries. Potter's hypothesis about misplacement of events toward the survey date, which assumes bunching of births five to ten years before the survey and accurate reporting of births during first five years or so immediately preceding the survey, resulting in a spurious estimated fertility decline, does not receive much support from these data. Some of the estimated fertility declines do indeed seem spurious, but Potter's explanation of them seems inconsistent with the data. In some countries, patterns of age misreporting involving upward rounding of children's ages provide an equally plausible explanation that is more consistent with the data. (Author)

Available in PDF, EPUB and Kindle. Book excerpt: By all indicators, the reproductive health of Americans has been deteriorating since 1980. Our nation is troubled by rates of teen pregnancies and newborn deaths that are worse than almost all others in the Western world. Science and Babies is a straightforward presentation of the major reproductive issues we face that suggests answers for the public. The book discusses how the clash of opinions on sex and family planning prevents us from making a national commitment to reproductive health; why people in the United States have fewer contraceptive choices than those in many other countries; what we need to do to improve social and medical services for teens and people living in poverty; how couples should "shop" for a fertility service and make consumer-wise decisions; and what we can expect in the futureâ€"featuring interesting accounts of potential scientific advances.
