The male and female reproductive systems consist of the gonads, testes or ovaries; the reproductive tract; the external genitalia; and the hypothalamic-pituitary unit. The functions of the reproductive system are to produce and deliver gametes, spermatozoa or oocytes, for sexual reproduction; and produce hormones that regulate reproductive function and secondary sex characteristics. Abnormalities in anatomic or physiologic function affect the development and delivery of gametes, and potential fertility. This book provides a comprehensive review of the anatomy and physiology specific to reproduction, emphasizing developmental and hormonal processes of gamete production, fertilization, implantation, and embryonic development. This review has been designed to meet the educational needs of physicians and allied health professionals who care for couples experiencing infertility. By developing a clear understanding of what is normal, you will better understand abnormalities affecting reproduction and the mechanisms behind treatment.

In 2004, the Assisted Human Reproduction Act was passed by the Parliament of Canada. Fully in force by 2007, the act was intended to safeguard and promote the health, safety, dignity, and rights of Canadians. However, a 2010 Supreme Court of Canada decision ruled that key parts of the act were invalid. Regulating Creation is a collection of essays built around the 2010 ruling. Featuring contributions by Canadian and international scholars, it offers a variety of perspectives on the role of law in dealing with the legal, ethical, and policy issues surrounding changing reproductive technologies. In addition to the in-depth analysis of the Canadian case the volume reflects on how other countries, particularly the U.S., U.K. and New Zealand regulate these same issues. Combining a detailed discussion of legal approaches with an in-depth exploration of societal implications, Regulating Creation deftly navigates the obstacles of legal policy amidst the rapid current of reproductive technological innovation.

Spermatogenesis is a tightly regulated cellular renovation and differentiation process. It consists of self-renewal and differentiation of spermatogonial stem cells (SSCs), spermatocytic meiosis and spermiogenesis; each of these processes is essential to the continuous, successful production of male gametes. During spermiogenesis, haploid spermatids undergo extensive cellular, molecular and morphological changes, including acrosome biogenesis, flagellum development, cytoplasmic reorganization and chromatin condensation. These changes ultimately result in mature spermatozoa with an acrosome-covered head and motile tail. In this book, Chapter One summarizes the progress that has been made in understanding the molecular mechanisms underlying acrosome biogenesis, and the authors discuss the potential directions of future investigations of this process. Chapter Two briefly addresses the basics of spermatogenesis and the synthesis of ncRNAs, and then the authors discuss the recent progress in understanding of the functions of miRNAs, endo-siRNAs, piRNAs and lncRNAs in the regulation of spermatogenesis. Chapter Three provides a review of the current literature on testicular immunoregulation and its underlying mechanisms, along with its effect on testicular functions.

One message that comes along with ever-improving fertility treatments and increasing acceptance of single motherhood, older first-time mothers, and same-sex partnerships, is that almost any woman can and should become a mother. The media and many studies focus on infertile and involuntarily childless women who are seeking treatment. They characterize this group as anxious and willing to try anything, even elaborate and financially ruinous high-tech interventions, to achieve a successful pregnancy.

But the majority of women who struggle with fertility avoid treatment. The women whose interviews appear in "Not Trying" belong to this majority. Their attitudes vary and may change as their life circumstances evolve. Some support the prevailing cultural narrative that women are meant to be mothers and refuse to see themselves as childfree by choice. Most of these women, who come from a wider range of social backgrounds than most researchers have studied, experience deep ambivalence about motherhood and non-motherhood, never actually choosing either path. They prefer to let life unfold, an attitude that seems to reduce anxiety about not conforming to social expectations.

Frank Nawroth thematisiert das Social Freezing und die zugehoerige Beratung, die nicht nur Chancen, sondern auch denkbare Komplikationen und Grenzen der Methode aufzeigen muss. Zum Beispiel haben die gesellschaftspolitisch nicht optimal geloeste Problematik des moeglichen Karriere-Nachteils einer berufstatigen Mutter oder die haufig bestehende Schwierigkeit, den geeigneten Partner zu finden, bei gleichzeitig verbesserten Kryokonservierungsmethoden dazu gefuhrt, dass Frauen ohne medizinische Indikation uber das Einfrieren ihrer Eizellen nachdenken. Die Technologie selbst ist seit Langerem Routine vor fertilitatsbeeintrachtigenden Therapien onkologischer Erkrankungen (Operation, Strahlen- und/oder Chemotherapie) im reproduktiven Alter.

Challenging Concepts in Obstetrics and Gynaecology is a case-based guide to difficult scenarios faced in both fields, covering many of the major sub-speciality areas of each. The 24 cases have been selected to cover a spectrum of challenges in obstetrics and gynaecology. Recognising that any attempt to cover the whole curriculum is impossible, the authors have instead chosen specific, challenging scenarios that are commonly encountered in clinical practice, but by no means have simple answers or outcomes. Complex cases are examined from a multidisciplinary approach with consideration of diagnostic procedures, practical skills, evidence base, and the application of national and international guidelines. There is also a summary of evidence from the medical literature in various subspecialty areas of obstetrics and gynaecology, alongside current controversies in management. Cases are punctuated by easy-to-read "Learning Points", "Clinical Tips", and "Evidence Base" boxes, speeding the learning process as well as providing a handy dip-into guide for those just refreshing their memory. Each case is set off by an 'Expert Commentary' written by an internationally-renowned expert in each field, leaving the reader with both a solid base of knowledge and a nuanced view of current challenges in obstetrics and gynaecology. This collaboration between trainees and experts provides a unique insight into the management of complex and often rare but important obstetrics and gynaecology cases, within a highly user-friendly format and a ready-made means of self-learning and self-testing. Challenging Concepts in Obstetrics and Gynaecologymakes a useful, relevant and interesting read, enabling the reader to readily transfer the knowledge gained to everyday clinical practice.

In this book the authors present current research in the study of foetal development and its stages of growth, maternal influences and potential complications. Topics discussed in this compilation include the equine foetal development, fetomaternal interaction and potential complications during pregnancy; comparative anatomy, development and functional significance of the mammalian yolk sac; influence of exercise training on e-NOS expression, nitric oxide production and mitochondrial function in the human placenta; maternal melamine and foetal development; and immunolocalisation of syntaxin2 in sinusoidal endothelial cells during mouse liver development.

Stuart and his wife Julie decided they were ready to have a baby. She went on vitamins and they went on one last vacation, because they thought it would be no time at all before she was pregnant. But that's not exactly how things went. For nearly two years, they endured grueling fertility treatments, beginning with charting temperatures and predicting ovulation, on to oral fertility drugs, through a laparoscopy, a slew of IUIs, and multiple IVFs, and, finally, a course of homeopathic remedies. Catawampus tells this tale of the madness and confusion of fertility treatments and all that those treatments entail but, this time, it's Stuart that tells the story. So, specimen collecting? Sure. Syringes, large and small? Yes. Heartache, frustration, and anger? Of course, but Stuart also shows what else was going on at the time, because, despite the fact that the fertility process can dominate a couple's focus, life continues to unfold. As such, the book is about a relationship between husband and wife, between parent and child, about friendship, and, ultimately, about what it means to be a father. Oh, yeah, it's also very funny. And filled with a choice selection of rants about popular culture, references to movies ranging from the ridiculous to the mostly-still-ridiculous, citations of literary classics, and a little bit of Nashville thrown in for fun. In the end, it's entertaining and poignant writing, and a necessary and underrepresented perspective of an important, hot-button issue.

The most important and the largest sex organ is located between the ears....and is commonly referred to as "the brain." Libido is a function of testosterone and erection is a function of free radicals. The very spark of life is fed by oxygen If you put out your free radical, oxidative fire, you extinguish your life If you douse your inner life-force spark, you smother your elan vital (life force). You can not live without your inner oxidative flame. Antioxidants pose a threat to the oxidative fire within. Oxygen and its electronically modified oxygen derivative (EMOD) progeny are the sine qua non (the essential condition) of man's very existence. This is an inarguable fact. Contrary to the common mantra of many authors, oxygen free radicals perform many crucial beneficial roles in sexual function and reproduction. Also contrary to popular claims, antioxidants are not the cure-all for sexual and reproductive problems. I have often said, "Man is the craziest critter on the planet." To back this up, I had suggested that all one had to do was to turn on the evening news or grab a newspaper. However, if you really want to see how crazy man is, just come with me through the history of aphrodisiacs and sexual prowess. So, let's undergo a reality check and scope out the history of these agents that claim to put more "zang in your wang," "zing in your thing" or greater "zippedy in your doo-da "

Thirty-five years after its initial success as a form of technologically assisted human reproduction, and five million miracle babies later, in vitro fertilization (IVF) has become a routine procedure worldwide. In Biological Relatives, Sarah Franklin explores how the normalization of IVF has changed how both technology and biology are understood. Drawing on anthropology, feminist theory, and science studies, Franklin charts the evolution of IVF from an experimental research technique into a global technological platform used for a wide variety of applications, including genetic diagnosis, livestock breeding, cloning, and stem cell research. She contends that despite its ubiquity, IVF remains a highly paradoxical technology that confirms the relative and contingent nature of biology while creating new biological relatives. Using IVF as a lens, Franklin presents a bold and lucid thesis linking technologies of gender and sex to reproductive biomedicine, contemporary bioinnovation, and the future of kinship.

Designed for students and practitioners, Materia Medica of Sexual Disorders comprehensively explains human sexual disorders and infertility problems in a therapeutic manner as defined in William Boericke's Materia Medica. In this study, author Nikunj Trivedi, who has worked more than twenty-eight years as a homeopathic practitioner, discusses the use of clinical homeopathy with a variety of reproductive diseases. Trivedi portrays the essential interrelationships between the disease and drug picture in a comparative manner and offers alternatives to those interested in practicing clinical homeopathy in disorders of reproductive conditions where prolonged use of conventional medicine results in side effects. With illustrations included, Materia Medica of Sexual Disorders offers a comprehensive review of both the male and female reproductive systems. It provides information on more than 300 homeopathic remedies and the treatment results for both males and females. This reference guide will help homeopathic clinicians in the effective treatment of their patients.
