Biology Medical Dynamics Of Human Reproduction

This book covers human female biology, how the menstrual cycle is controlled, how steroidogenesis is controlled and how the follicle and the egg are formed. This book covers male biology, and how steroid hormones are made, and how sperm are synthesised and matured. Then this book covers sex biology, such as how the brain deals with libido and sexual images, and how the brain controls erection and ejaculation. This book deals with how sperm are matured upon intercourse, how fertilisation takes place, and how the fertilised embryo is matured and implants in the uterus. The subjects of sexuality and homosexuality, chromosome disorders and hydatidiform moles are carefully discussed and considered.

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.

"...a 'must-have' reference text for any researcher interested in the biocultural determinants of human fertility and is appropriate as a textbook at the graduate level. I expect it to remain a standard in the literature of demographic anthropology and reproductive ecology for many years to come." --American Journal of Physical Anthropology

Our knowledge of reproductive biology has increased enormously in recent years on cellular, molecular, and genetic levels, leading to significant breakthroughs that have directly benefitted in vitro fertilization (IVF) and other assisted reproductive technologies (ART) in humans and animal systems. Animal Models and Human Reproduction presents a comprehensive reference that reflects the latest scientific research being done in human reproductive biology utilizing domestic animal models. Chapters on canine, equine, cow, pig, frog, and mouse models of reproduction reflect frontier research in placental biology, ovarian function and fertility, non-coding RNAs in gametogenesis, oocyte and embryo metabolism, fertilization, cryopreservation, signal transduction pathways, chromatin dynamics, epigenetics, reproductive aging, and inflammation. Chapters on non-human primate models also highlight recent advancements into such issues as human in vitro fertilization (IVF) and assisted reproductive technologies (ART). This book offers animal scientists, reproductive biology scientists, clinicians and practitioners, invaluable insights into a wide range of issues at the forefront of human reproductive health.

Reproduction plays a huge part in many people's lives, but often little is understood about the biological processes involved and the larger impact of reproductive choices. This book offers an accessible, comprehensive introduction to this fascinating subject. Irina Pollard takes a unique, interdisciplinary perspective, describing in detail the biology of human reproduction, but also covering in depth the impact of procreational behavior on human social structures, the environment, and health. This compelling and authoritative account is the first to draw together in a single volume these two disparate yet intimately connected strands of the story of human reproduction. The book covers fertility and infertility, sexual behavior and pheromones, sperm creation, maternal physiology during pregnancy, fetal development, the biology of breast feeding, and the impact of parental behavior on the physiology of the newborn, as well as population dynamics, artificial control of fertility, the AIDS epidemic, the effects of nutrition and exercise on reproductive behavior, and the causes of birth defects, including abuse of substances such as nicotine, alcohol, and caffeine. This book is an ideal text for undergraduate and graduate students studying biology, medicine, anthropology, human ecology, population dynamics, and public health. It is also an engrossing and enlightening source of information for a wide range of general readers including prospective parents, pregnant mothers, teenagers, and anyone wishing a concise, up-to-date review of human reproductive biology.

Human Reproductive Biology focuses on the processes, concerns, and trends in human reproduction. Divided into four parts with 19 chapters, the book starts by tracing the history of human reproduction biology and the questions and choices involved. The first part focuses on the male and female reproductive systems. The text notes the different organs involved in reproduction, including the penis, scrotum, vagina, oviducts, and mammary glands. The book discusses sexual development and differentiation, particularly noting the variance of sex ducts and glands, external genitalia, and disorders of sexual development and determination. The text also looks at puberty. Concerns include gonadal changes from birth to puberty; mechanisms that influence puberty; and puberty and psychosocial adjustment. The second part deals with menstrual cycle, fertilization, pregnancy, labor, and birth. Some of the concerns include length of menstrual cycle; absence of menstruation; transport of sperm and ovum in the oviduct; and semen release. The text also highlights labor and birthing processes as well as the relationship of neonates and parents. The third part looks at the medical aspects of human reproduction, infertility, and sexually transmitted diseases. Concerns include contraception, abortion, herpes genitalis, and vaginitis. The text folds with discussions on human sexual behavior, population growth, and family planning. Concerns include sexual dysfunction; the effects of overpopulation; and population control. The book is a vital source of data for readers interested in human reproduction.

Human Reproduction at a Glance is designed to be a concise, readily accessible guide and revision aid for undergraduate medical students. Following the now familiar, easy-to-use format, each topic is presented as a double-page spread with key facts accompanied by clear, but informative line diagrams illustrating the essential points. Human Reproduction at a Glance explores the breadth of human reproductive biology and pathophysiology in 42 separate sections, giving the student the basic science required to understand the disorders they will encounter during a clinical OBGYN rotation. Divided into 2 parts: Normal Human Reproduction and Human Reproductive Disorders, the book takes an integrated approach throughout, emphasizing the relationship between normal and abnormal reproductive function and disease. Designed to be versatile, Human Reproduction At A Glance fits the reading time and budget of all medical students and can be used either for primary or supplementary reading in a lecture-based course or for exam preparation.
