Query: Complete insight information on how it all works

A very complete book covers all the topics that are related to the reproductive system. I've been searching for this kind of book a long time because it is not your basic story book reading. At last not the standard material which you will find in all the popular books. This book gives you all the details and the background you need to fully comprehend this system. It took me some time to understand all the matters that are addressed to. If you want some story telling book without a good comprehension of the deeper material don't buy this book. If you really want to know how it works I really would recommend this book.
