Lesson 9.1

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.
What are the parts of a sperm cell and what is the sperm cell’s purpose?

How does sperm navigate?

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.
Ask students to describe the process of fertilization.

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

What is the difference between fraternal and identical twins?

Which twins are a perfect genetic match?

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).
Describe the role of testosterone.

What is the difference between the number of eggs vs. sperm cells?
