Testosterone takes a historical approach to understanding testosterone. It is a comprehensive description of the functions of testosterone and its role in determining the biological, medical, psychological, behavioral and cultural features of the male sex/gender and the male/female differences.It is a unique reference that explains not only the biological aspects of the function of testosterone, but also the psychophysical aspects. Unlike most other hormones, testosterone not only regulates biological functions of the body, but its functions are also psychological. This wide spectrum of effects influences nearly all biological and behavioral features of a male, makes testosterone particularly exciting.Sex/gender issues are of great interest for a wide readership of experts within various disciplines and specialties including GP, gynecology, pediatrics, urology, andrology, and endocrinology.- Discusses groundbreaking discoveries about the function of endocrine glands and hormones from the 19th century until present- Includes information on the biology of testosterone production and its effects in men and women, including effects of high and low testosterone- Presents male contraception with its successes and failures as well as future directions and strategies in the development of novel effective male contraceptives- Discusses the correct, questionable and misuse of testosterone treatments

This book summarizes the current understanding of fetal Leydig cells, adult Leydig cell formation and function, hormonal and paracrine regulation of adult Leydig cell function, Leydig cell aging, the causes, consequences, and treatment of reductions in testosterone, and how new technologies might be used for both greater understanding of Leydig cell function and for treatments related to aging- and/or lifestyle-related alterations in Leydig cell function. Chapters are divided into three sections, each focusing on a key aspect of Leydig cell function. These sections are: Leydig Cells from Fetus through Aging, Leydig Cells Steroidogenesis Regulation and Mechanisms, and Leydig Cell Function in Health and Pathophysiology. Written by experts in the field, this book provides a comprehensive approach to the hormone production, function, and pathophysiology of Leydig cells from the fetal to adult stage of development.Leydig Cells: Formation, Regulation and Function in Health and Pathophysiology will be of particular interest to those involved with men’s health and disease, including reproductive medicine, endocrinology, urology, oncology and prenatal and postnatal development of male reproductive function.

Testosteroni on pääkonna urheilijoiden dopingissa ja käyttövoima setämiesten toksisessa maskuliinisuudessa. Se ajaa taloudelliseen riskinottoon ja piittaamattomaan politiikkaan. Toisaalta hormoni voi parhaimmillaan tehdä miehestä anteliaan ja suojelevaisen jalon ritarin.Hyvä ja paha testosteroni kokoaa yhteen tutkimustietoa testosteronista. Vaikka monelle tulevat hormonista mieleen lähinnä seksi, aggressio ja kehonrakentajien pullistelevat lihakset, se vaikuttaa lukuisin tavoin miehen terveyteen ja käyttäytymiseen.Teoksessa kumotaan myyttejä testosteronista ja pureudutaan sen väärinkäyttöön ja hyväksyttyyn lääkinnälliseen käyttöön. Miten ikääntyminen vaikuttaa testosteronitasoihin? Mitä tapahtuu, jos testosteronia on liian vähän? Entä voisiko sitä hyödyntää miehen ehkäisymenetelmänä?
