Module 3 Lesson 1 - 1

Get Focused

---

For reproduction and perpetuation of the species, functional gametes must be formed. To form functional gametes, supporting structures must help develop and protect the sperm and egg cells. For most couples, these structures function as they should. However, for some couples, these supporting structures do not function well and problems with fertility can occur. Infertility is a result of an abnormality in either the sperm or the egg or the body's ability to support conception to birth.

Lesson 1 investigates the male reproductive system and many issues that affect male fertility. You will consider the following focusing questions:

• What are the main structures and functions of the male reproductive system?
• How do these structures support continuity of the human species?
• What is the functional unit of the male reproductive system?
• How do sperm cells develop into functional gametes?
• What supporting structures help in the development of a fully functional gamete?
