Hormones and Embryonic Development


Book Description

Advances in the Biosciences 13: Hormones and Embryonic Development investigates various aspects of hormones and embryonic development, including their physiological and pharmacological effects. More specifically, this volume considers which maternal hormones are essential for normal mammalian embryonic development, as well as the time course of the occurrence of endocrine systems during mammalian fetal development. In addition, it examines the role of maternal or fetal hormones in the induction and differentiation processes during embryonic or fetal development. Comprised of 13 chapters, this book begins with an analysis of the metabolic effects of insulin and glucagon in fetal and newborn rats, as well as their physiologic significance during the perinatal period in rat and other species. The next chapter deals with sexual differentiation in the rat fetus; how hormones regulate sexual development and disrupt sexual differentiation; the role of progesterone and estrone in pregnant rats fed a protein-free diet; and effects of brain implants of testosterone propionate in newborn hamsters on sexual differentiation. The link between diethylstilbestrol ingestion during pregnancy and development of clear-cell adenocarcinoma in the vagina and cervix of the female offspring is also examined. This monograph will be of interest to biologists, bioscientists, physiologists, and pharmacologists.

Exploring the Biological Contributions to Human Health


Book Description

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.

Fetal Endocrinology


Book Description

Fetal Endocrinology covers many facets of primate reproductive biology. The book discusses some thoughts on the fetoplacental unit and parturition in primates; the development and function of the human fetal adrenal cortex; and postnatum evolution of the adrenal glands of rhesus macaques. The text also describes the regulation of fetoplacental steroidogenesis in rhesus macaque; the comparative biological, immunologic, and chemical properties of the primate chorionic gonadotropins; and urinary estrogens during pregnancy in diverse species. The secretion and physiology of chorionic somatomammotropin in primates; the placental thyroid stimulators and thyroid function in pregnancy; and growth factors in fetal growth and development are also considered. The book further tackles the production and activity of placental releasing hormone; the endocrinology of parturition; and sex-determining genes and gene regulation. The text also looks into the testicular hormone production in fetal rhesus macaque; the control of pituitary gonadotropin secretion in fetal rhesus macaque; and the development of the regulatory mechanisms of the hypothalamic-pituitary-gonadal system in the human fetus. The development of the fetal adrenals in nonhuman primates and perspectives in fetal endocrinology are also encompassed. Reproductive physiologists, pediatricians, gynecologists, and endocrinologists will find the book invaluable.




Endocrinology of Pregnancy


Book Description

A comprehensive, cutting-edge review of the complex interactions between maternal and fetal-placental tissues that control the establishment and maintenance of pregnancy, the proper development of the fetus, the birth process, and the behavioral aspects of bonding between mother and newborn. Expert researchers review the endocrine and physiological events that culminate in the delivery of offspring, and provide a solid base of comparative information on the menstrual cycle of primates, including humans. They also discuss the sources and functions of both steroid and protein hormones from the placenta and the details of their effects on uterine function, placental development, fetal growth and well-being, and maternal responses to pregnancy. This book will become the standard reference source not only for reproductive scientists, but also for those clinicians who want better to understand the complex factors that affect pregnancy-and their pregnant patients.










Hormonal Control of Reproduction


Book Description

In this, our Second Edition of Reproduction in Mammals, we are responding to numerous requests for a more up-to-date and rather more detailed treatment of the subject. The First Edition was accorded an excellent reception, but the first five books were written ten years ago and inevitably there have been advances on many fronts since then. As before, the manner of presentation is intended to make the subject matter interesting to read and readily comprehensible to undergraduates in the biological sciences, and yet with sufficient depth to provide a valued source of information to graduates engaged in both teaching and research. Our authors have been selected from among the best known in their respective fields. This volume discusses the manifold ways in which hormones control the reproductive processes in male and female mammals. The hypothalamus regulates both the anterior and posterior pituitary glands, whilst the pineal can exert a modulating influence on the hypothalamus. The pituitary gonadotrophins regulate the endocrine and gametogenic activities of the gonads, and there are important local feedback effects of hormones within the gonads themselves. Non-pregnant females display many different types of oestrous or menstrual cycles, and there are likewise great species differences in the endocrinology of pregnancy. But the hallmark of mammals is lactation, and this also exerts a major control on subsequent reproductive activity.
