The Reproductive System
• What does the reproductive system do?
• How do the parts of the male reproduction
system work together?
• How do the parts of the female reproductive
system work together?
Functions of the Reproductive System
A reproductive system is a group of
tissues and organs in humans. It enables
the male and female reproductive cells
to join and form new offspring.
 Human males produce sperm, the male
reproductive cells, and human females
produce ova (eggs), the female
reproductive cells.

Functions of the Reproductive System
(cont.)
During reproduction, a sperm joins with an
ovum (egg) inside a female’s reproductive
system.

The Male Reproductive System


The main function of
the male
reproductive system
is to produce and
transport sperm to
the female
reproductive system.
The testis is the male
reproductive organ
that produces sperm.
The Male Reproductive System (cont.)
Once sperm develop, they move to a
tube called the sperm duct where
they are stored.
 As mature sperm move through the
remainder of the male reproductive
system, they mix with fluids
produced by several glands creating
a mixture called semen.

The penis is a tubelike structure that delivers
sperm to the female reproductive system.
The Female Reproductive System




Female reproductive
systems produce
immature eggs called
oocytes.
An ovary is an organ
where oocytes are stored
and mature.
A mature oocyte is called
an egg, or ovum.
Females have two
ovaries.
The Female Reproductive System (cont.)
About once a month, an ovary releases
an egg into the fallopian tube.
 Short, hairlike structures called cilia
move the egg through the fallopian tube
toward the uterus.
 If the egg is fertilized by a sperm,
the uterus provides a nourishing
environment for a fertilized egg’s
development.
