دانلود کتاب تستوسترون از جنبه های اساسی تا بالینی

When I received the invitation from Springer in 2014, I did not imagine exactly what this book project would become.
We launched the first edition in 2017 and I was surprised by the success of the book in different parts of the world. In 2019, the book was released in Portuguese in Brazil, my home country.
After a few years, we observed the need to expand on some important key points regarding the hormone “testosterone.” Topics such as gynecomastia, male infertil¬ity, anabolic steroids, and transgenderism were incorporated in this edition.
In recent years, we have seen a worsening of testosterone use and abuse, not only among men, but also among women. The phenomenon is global and worries health authorities and medical societies in different countries.
Revisiting the hormonal physiology of sex steroids in men and women, the actions of androgens and their binding to the respective receptor, the development of male sexual characteristics that fundamentally depend on testosterone and its derivatives, form the basis of the book.
As well as the different causes of male hypogonadism, central and peripheral, organic and functional, the respective differential diagnoses are described in detail in different chapters.
Testosterone, the focus hormone of this book, is used in different forms and routes of administration. Several authors unravel its peculiarities and assist in choos¬ing the most suitable form in each case, as well as the possible risks of its misuse or even abuse in men and women, seeking alternatives to help patients in this situation.
I hope every reader will take advantage of this book as a source of knowledge to improve medical practice in different parts of the world.
