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.

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.

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.

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.

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.

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: 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.

Book excerpt: How often is male idiopathic infertility diagnosed nowadays? It is estimated that 70% of male infertility is apparently idiopathic because its etiology cannot be found despite a complete diagnostic procedure. Epidemiological studies have highlighted that sperm concentration and total count have halved in the past forty years. The reasons for this decline are still unknown and, therefore, it is urgently necessary to research the etiopathogenetic moments. Given that Sertoli cells are responsible for supporting spermatogenesis, much attention should be focused on their function. During childhood, these cells have peculiar characteristics. After the onset of puberty, they reach a state of maturity and lose their ability to proliferate. Therefore, several environmental or lifestyle factors in childhood could reasonably interfere with the proliferation of Sertoli cells and this may be the cause of so-called idiopathic infertility in adulthood. For that reason, this book explores molecular aspects involving prepubertal Sertoli cells, risk factors for infertility in the early stages of life, and the correct management of andrological health from the first months of life and during infancy and adolescence. A close collaboration between pediatricians, endocrinologists, and andrologists is of fundamental importance to achieve an important goal: To protect the health of the fathers of tomorrow!

Book excerpt: Previously known as Biennial Review of Infertility, the fifth installment in this series brings together the most current research and clinical evidence on male and female infertility, emerging assisted reproductive technologies (ART) and evolving controversies in reproductive medicine. In this latest volume, parts one and two discuss recent developments in male and female infertility respectively, including fertility preservation in the male adolescent cancer patient, the clinical relevance of sperm RNA, the management of subclinical hypothyroidism, and the effects of endocrine-disrupting chemicals. Part three covers the latest in ART, such as evidence-based morphological approaches for embryo selection and culturing human embryos. The final section highlights controversies in reproductive medicine, including the use of preimplantation genetic screening (PGS) and blastocyst transfer, as well as the ethics surrounding a maximum BMI for IVF. Providing an ongoing appraisal of current knowledge, and featuring contributions from leading experts in the field, Emerging Topics in Reproduction, Volume 5 is a worthy addition to the series and an ideal resource on the latest topics for reproductive medicine and REI specialists, OB-GYNS, andrologists, and any clinician working with infertility.
