Professor Piet Hoebeke Reihenfolge der Bücher (Chronologisch)

In this book, urologist Piet Hoebeke clarifies the mysteries of the male reproductive organ. Accessibly and humoristically written, Hoebeke explains the penis: Why do we have one? What does it do? How do I keep it fit and healthy? And of course: what to do when your foreskin gets stuck between the zipper of your pants?
