This document provides an overview of the male reproductive system including its anatomy, functions, pathologies, sexually transmitted diseases, laboratory tests, clinical procedures, terminology, and abbreviations. It begins with an introduction to sperm cells and their role in fertilization. The major sections then cover anatomy of the reproductive organs, pathologic conditions like hypospadias, common sexually transmitted diseases, relevant laboratory tests and procedures, medical terminology, and abbreviations. The goal is to educate the reader on the key aspects of the male reproductive system and related topics.

Introduction
• The male sex cell is called a
spermatozoon, or sperm cell.
• The sperm cell carries its nuclear
hereditary material, or chromosomes, in
its head region.
• The tail consists of a flagellum, which
makes the sperm cell mobile.

7. Copyright © 2014, 2011, 2007 by Saunders, an imprint of Elsevier Inc. 7
Introduction (cont’d)
• Only one spermatozoon out of 300
million sperm cells released during
ejaculation can fertilize a single female
ovum.
• If more than one egg is present in the
fallopian tubes during ejaculation,
multiple fertilizations are possible.

8. Copyright © 2014, 2011, 2007 by Saunders, an imprint of Elsevier Inc. 8
Introduction (cont’d)
• Twins resulting from the
fertilization of separate
ova by separate sperm
cells are called fraternal
twins.
• Twins resulting from the
fertilization of a single
egg by a single sperm are
called identical twins.
Fraternal twins. Notice the 6-week-old
embryos in two separate amnionic sacs..

9. Copyright © 2014, 2011, 2007 by Saunders, an imprint of Elsevier Inc. 9
Introduction (cont’d)
• The organs of the male reproductive
system are designed to produce and
release billions of sperm cells
throughout the man’s lifetime.
• The hormone called testosterone is
responsible for the bodily characteristics
of the male (such as beard, pubic hair,
and deeper voice).
