- Abstract
This book discusses the nature of meiotic chromosome pairing effects which may play a role in the determination of fertility. In particular, data and illustrations from the application of recently developed electron microscopic spreading techniques will allow researchers in related fields to come to grips with the recent advances in the cytogenetics of meiotic chromosome pairing behavior. Topics dealt with include meiotic and synaptonemal complex behavior in humans and mice with a variety of chromosomal and genetic abnormalities, sex chromosome pairing in mammals and birds, the significance for fertility or pairing in mammals and birds, the significance for fertility of XY pairing and crossing over, the effects of hybridity on pairing and fertility in plants, and the genetic control of synaptonemal complex formation and crossing over in polyploids. This is a timely reference book for graduate level medical and veterinary students, and scientists in the field of genetics and cell biology.

- Abstract
In recent years increasing numbers of women from wealthy countries have turned to egg donation, egg freezing, and in vitro fertilization to become pregnant, especially later in life. This trend has created new ways of using, exchanging, and understanding oocytes—the reproductive cells specific to women. In The Oocyte Economy Catherine Waldby draws on 130 interviews---with scientists, clinicians, and women who have either donated or frozen their oocytes or received those of another woman---to trace how the history of human oocytes'perceived value intersects with the biological and social life of women. Demonstrating how oocytes have come to be understood as discrete and scarce biomedical objects open to valuation, management, and exchange, Waldby examines the global market for oocytes and the power dynamics between recipients and the often younger and poorer donors. With this exploration of the oocyte economy and its contemporary biopolitical significance, Waldby rethinks the relationship between fertility, gendered experience, and biomedical innovation.

- Abstract
This unique book provides expert advice on all the different aspects related to fertility preservation for age related infertility. Although, there is a lot of information available on the Internet and in books about fertility preservation for cancer treatment, little information is available for young women that are confronted with a ticking biological clock. While men have been able to cryopreserve sperm since the 1950s, women have only recently gained the opportunity to preserve their gametes through the egg vitrification technique. Therefore, many women confronted with a risk of imminent fertility loss, such as chemotherapy, are now freezing their oocytes instead of embryos. Successful oocyte cryopreservation offers them a reproductive autonomy independent of men. Moreover, it now enables single women to preserve their reproductive chances. The most important threat for female fertility is ovarian aging as it causes a progressive decline in the reproductive chances. The generaltrend to delay motherhood due to societal changes confronts many women and couples with a diminished fertility. This fertility problem can often not be cured by in vitro fertilization, which makes that an increasing number of women require oocyte donation as the treatment of last resort. In the last few years, fertility centres around the world have started to offer the opportunity cryopreserve oocytes to young, often highly educated, single women. This patient population is unique as compared to other patients in the fertility clinic as they perform a preventive treatment. They are neither confronted with infertility nor are they undergoing a treatment that might cause an imminent treat to their fertility.

- Abstract
Awarded the W. W. Howells Award for the Outstanding Book in Biological Anthropology, this volume presents a comprehensive, integrated, and up-to-date overview of the major physiological and behavioral factors affecting human reproduction. In attempting to identify the most important causes of variation in fertility within and among human populations, Wood summarizes data from a wide range of societies. Trained as an anthropologist as well as a demographer, he devotes special attention to so-called''natural fertility''populations, in which modern contraceptives and induced abortion are not used to limit reproductive output. Such an emphasis enables him to study the interaction of biology and behavior with particular clarity.The volume weaves together the physiological, demographic, and biometric approaches to human fertility in a way that will encourage future interdisciplinary research. Instead of offering a general overview, the focus is to answer one question: Why does fertility and the number of live births vary from couple to couple within any particular population, and from population to population across the human species as a whole?Topics covered include ovarian function, conception and pregnancy, intrauterine mortality, reproductive maturation and senescence, coital frequency and the waiting time to conception, marriage patterns and the initiation of reproduction, the fertility-reducing effects of breastfeeding, the impact of maternal nutrition on reproduction, and reproductive seasonality. This unique combination of comprehensive subject matter and an integrated analytical approach makes the book ideally suited both as a graduate-level textbook and as a reference work.

- Abstract
Fertility Awareness is key to understanding sexual and reproductive health at all life stages. It can be used to either plan or avoid pregnancy. Fertility Awareness Methods (FAMs) are highly effective when motivated couples are taught by trained practitioners. These methods are in demand for ecological, medical, cultural, religious and moral reasons. The ability to control fertility naturally is a lifestyle choice. The Complete Guide to Fertility Awareness provides the science and methodology suitable for health professionals and a general audience. It covers reproductive physiology and the fertility indicators: temperature, cervical secretions and cycle length calculations. It explores ways to optimise conception and to manage conception delays. Case studies and self-assessment exercises are included throughout. The book addresses the scientific credibility of new technologies including fertility apps, home test kits, monitors and devices.The Complete Guide to Fertility Awareness offers: evidence-based information for general practitioners, practice nurses, school nurses, midwives, sexual health doctors and nurses a unique perspective on subfertility for gynaecologists and fertility nurses an authoritative source of reference for medical, nursing and midwifery students a straightforward and practical reference for new and experienced FAM users the core text for the FertilityUK Advanced Skills Course in Fertility Awareness

- Abstract
Advances in technology now offer promising solutions to deal with the chronological aging of the cell, tissue or organ to synchronize its existence and its use. This book covers the developments in and benefits of the latest vitrification technology and its extensive applications in reproductive medicine. Protocols of gametes (oocyte and sperm), embryos, blastocysts and ovarian tissue cryopreservation have been reviewed by leaders in the field. In order to address the escalation in cross-border reproductive tourism entailing the transfer of reproductive cells and tissues rather than the patient, the challenges, caution and emerging possibilities of nitrogen vapor shipment of vitrified cells have been discussed. Current perspectives on oocyte banking present the reader with options and solutions to effectively utilize these gametes despite the physiological deterrents.The versatile applications and potential of vitrification of human embryonic stem cells, discussed in the concluding chapter, is an exciting reality offered by vitrification to help overcome numerous stumbling blocks in the management of various disorders.

- Abstract
Over the past 10 years, studies have shown that the rates of fertility vary in different ethnic groups. Ethnic differences also play a significant role in the outcome of assisted reproductive technology (ART) cycles. In the United States, minority groups--African Americans, Hispanics (mainly Mexicans and Central Americans), East Asians (Chinese, Japanese, Koreans, Philippinos) and South Asians (Indians, Pakistanis, and Bengalis)--have significantly lower chances of live births compared to Caucasian women. Birth outcome data collected by the Society for Assisted Reproductive Technology shows a worsening trend in conception rates between the years 1999-2000 and 2004-2006, raising more concern that the disparity in fertility rates between minority groups and white women is widening over time. This comprehensive book serves to answer the questions that arise when managing infertility in a multi-ethnic population. An expert assembly of key leaders in the field of reproductive medicine imparts insight and clinical experience in order to identify and analyze the possible causes of racial disparities in fertility outcome. Some of the reviewed causes include higher Body Mass Index (BMI), tubal diseases, metabolic syndrome, and fibroids in African Americans; tubal disease and higher early pregnancy loss in Hispanics; higher incidence of diminished ovarian reserve and lower BMI in East Asians; and higher incidence of polycystic ovarian disease (PCOS) in South Asians. The book also provides a review of data on access to care and ART services in developing countries. A thoughtful combination of evidence-based medicine and advanced treatment options, this book is sure to distinguish itself as the definitive reference on ethnic differences in assisted reproduction.

- Abstract
Studies on Men's Health and Fertility provides a comprehensive series of up-to-the-minute reviews addressing the role of oxidative stress in the aetiology of reproductive pathologies in the male. This volume represents by far the most detailed, authoritative review of the field that has been produced to date. The text encompasses the basic science of reactive oxygen species (ROS) production by mammalian spermatozoa, the way in which these highly reactive molecules are processed by the germ line and the physiological significance of this redox activity in the generation of a functional gamete. The factors responsible for perturbing the delicate balance between physiological redox signaling on the one hand and oxidative stress on the other are also extensively reviewed and some of the first clues concerning the underlying mechanisms (age, heat, infection, cryostorage, aberrant lipid metabolism), clearly identified. From a clinical perspective there are chapters setting out the methods we should be using to diagnose oxidative stress in the male germ line, a clinical perspective on the aetiology of this condition and detailed considerations of the most suitable means of ameliorating such stress from a therapeutic point of view. Studies on Men's Health and Fertility is intended to provide clinicians and scientists with a snap shot of the current status of this exciting, rapidly moving field. The book will be of value to clinicians interested in strategies for the management of oxidative stress in their infertility patients and scientists wishing to understand the molecular mechanisms underpinning the generation of ROS by these cells and its pathophysiological significance. It was not so long ago that the ability of spermatozoa to generate ROS was a hotly disputed topic. With the publication of this book such doubts can finally be laid to rest. There is now no doubt that these cells actively generate ROS, that oxidative stressis a major contributor to defects in male reproductive health and that the successful clinical management of this condition depends on developing a deeper understanding of the underlying molecular mechanisms. In this quest, Studies on Men's Health and Fertility will be seen as a clear and important milestone.

- Abstract
In the space of one generation major changes have begun to take place in the field of human reproduction. A rapid increase in the control of fertility and the understanding and treatment of sexual health issues have been accompanied by an emerging threat to reproductive function linked to increasing environmental pollution and dramatic changes in lifestyle. Organised around four key themes, this book provides a valuable review of some of the most important recent findings in human reproductive ecology. Major topics include the impact of the environment on reproduction, the role of physical activity and energetics in regulating reproduction, sexual maturation and ovulation assessment and demographic, health and family planning issues. Both theoretical and practical issues are covered, including the evolution and importance of the menopause and the various statistical methods by which researchers can analyse characteristics of the menstrual cycle in field studies.

- Abstract
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.

- Abstract
Fertility and Pregnancy: An Epidemiologic Perspective, is a lively overview of human reproduction: how it works, and what causes it to go wrong. Weaving together history, biology, obstetrics, pediatrics, demography, infectious diseases, molecular genetics, and evolutionary biology, Allen Wilcox brings a fresh coherence to the epidemiologic study of reproduction and pregnancy. Along the way, he provides entertaining anecdotes, superb graphs, odd tidbits and occasional humor that bring the topic to life. The book is divided into two sections. The first lays the foundations - the basic principles of reproductive physiology, demography, infectious diseases, and genetics as they apply to human reproduction. The second part deals with the endpoints of reproductive epidemiology - a spectrum ranging from infertility and fetal loss to birth defects and the delayed effects of fetal exposures. The book closes with a discussion of unsolved problems, suggesting possible research projects for a new generation of epidemiologists. An extensive glossary makes this a valuable reference as well as an enjoyable read.

- Abstract
Many technologies exist for men and women to preserve fertility, and advances are being made all the time. Sadly, this information is not always well known in the oncology community and is, therefore, not presented to all eligible cancer patients. Reflecting the latest advances in the field and offering practical information useful to clinicians and scientists, Preservation of Fertility addresses new concepts, progress in reproductive techniques, novel treatment modalities, pregnancy after cancer treatment, patient care issues, and professional responsibilities. Tulandi and Gosden have assembled an outstanding group of internationally recognized specialists to address the entire spectrum of issues regarding fertility preservation. They begin with a discussion of age and fertility, epidemiology of cancer survival and fertility, and the vulnerability of the reproductive system to radiotherapy and chemotherapy. The book includes coverage of methods for preserving fertility, new developments in the laboratory for preserving gametes and gonadal tissue, and the psychosocial, legal, and ethical issues of fertility preservation. A powerful knowledge tool for the medical community, this pioneering book provides a complete understanding of the techniques for preserving fertility.
