Male fertility rates are falling worldwide. The Y chromosome shrinks in size over generations and may eventually disappear during evolution. These colleagues demonstrated a high proportion of X chromosome sperm in the ejaculate and suggested that Y chromosome sperm be eliminated during their passage through the male reproductive tract. However, male embryos are well preserved in the womb. At birth, 106 males are born for every 100 females. Men in all age groups are more susceptible to disease and death, and as a result there are more elderly women than men in many parts of the world. While men maintain their fertility until old age, women lose their fertility in middle age. Males are biologically predisposed to be aggressive and polygamous, potentially increasing gene diversity. Male sexuality and reproduction have always been a mystery.

The truth is expressed by writers in different ways, in their own way; Not every book can serve everyone and be appreciated everywhere in the world. Every book creates a readership. Therefore, many books may need to cover the same body of knowledge, keeping a common readership in mind. Here, we present up-to-date andrology information to our readers with our own methods.

This book covers various aspects of the male reproductive system, from the brain to the testicles. This book is intended for all students and practitioners in medical science disciplines. We kept the language simple so that even a biomedical researcher could read it. The breadth of our book is also reflected in the diversity of articles reviewed by our contributors.

There are 30 chapters in this book, from chromosomes to yoga. The root of masculinity lies in the Y chromosome. Reproductive function depends on the mental development of the male organ from embryo to man. The male’s gonad, the testicle, produces hormones and sperm; the latter is discharged into the excretory ducts of the accessory glands. Testicular tumors are the underlying neuroendocrine system that regulates reproductive life from puberty to andropause and end of life.

Biology is as important as psychology in reproductive control. The root of behavior is in the brain. Various brain regions and neural networks regulate male behavior. Brain polymorphism is the basis of homosexuality and transgenderism. Understanding neurophysiology has always been difficult. However, we tried to explain this in a simple way. The reproduction of the also creates practical effects. This book describes the metabolic, immune, and thyroid roles in reproduction. The book includes sections on male reproduction. Assessment and management principles are also included. The final section is on family planning and yoga. The traditional wisdom of yoga has been used for centuries to enhance sexual experience.

Learning objectives are provided at the beginning of each chapter to provide an overview of the content. Ideas are presented using diagrams, tables and pictures. At the end of each chapter some important questions are given for the reader to think about.

We hope that this book will be helpful to general practitioners, urologists, nephrologists, surgeons and andrologists, endocrinologists, gynecologists, nurses, counselors, and students of biological sciences who wish to study human reproduction.

Dr. Manish Jain, MD. We thank Bodhana Dhole, Ms. Amanpreet Kaur Kalsi and artist Mr. Ramchandra Pokable for their great efforts in creating this book in its current form.

We are waiting for your suggestions about this book. I hope you enjoy reading!
