The female endocrine glands that release mature
eggs and produce the hormones estrogen and
progesterone

• ovaries

A pear-shaped organ, located within the pelvis,
in which the developing baby is nourished and
protected

• uterus

The process by which the ovaries release mature
eggs, usually one each menstrual cycle

• ovulation

3
The flow from the body of blood, tissues, and
fluids that results from the breakdown of the
lining of the uterus

• menstruation

The joining of a male sperm cell and a female egg
cell to form a fertilized egg

• fertilization

A doctor who specializes in the female
reproductive system

• gynecologist

4

• In this lesson, you will learn to
• describe the function of the female reproductive
  system.
• identify the organs and structures of the male
  reproductive system.
• explain how to care for the female reproductive
  system.
• apply the skill of advocacy to promote breast
  self-examinations.

Sequencing Before you read this lesson, take a
look at the major headings, figures, and photo
captions. Then write down two questions that you

Parts of the Female Reproductive System

• Two important parts of the female reproductive
  system are the ovaries and the uterus.

ovaries The female endocrine glands that
release mature eggs and produce the hormones
estrogen and progesterone

pelvis, in which the developing baby is
nourished and protected

The Menstrual Cycle

• The menstrual cycle is the series of events that
  prepares the female reproductive system for
  reproduction.

9
The Menstrual Cycle
Hormones cause the lining of the uterus to
build up with a cushion ofblood, tissue, and
fluid.
The level of estrogen reaches its highest
pointduring the cycle.
Ovulation occurs. The egg travels through the
fallopian tube towardthe uterus.
ovulation The process by which the ovaries
release mature eggs, usually one each menstrual
cycle
10
The Menstrual Cycle

• If the egg is not fertilized, the lining of the
  uterus begins to break down and menstruation
  occurs.

menstruation The flow from the body of blood,
tissues, and fluids that result from the
breakdown of the lining of the uterus
After menstruation, the cycle begins again.
11
Parts of the Female Reproductive System
Menstrualflow stops afterabout 5 days.
Ovulation occurs.An ovary releases amature egg
into afallopian tube.
Menstrualflow begins.
If fertilization has notoccurred, the
uterinelining begins to breakdown.
Fertilization is mostlikely to occur
duringthese days.
12
Fertilization

• If fertilization is successful, an egg develops
  into a baby.

fertilization The joining of a male sperm cell
and a female egg cell to form a fertilized egg
An egg that travels to the uterus and is not
fertilized eventually dissolves.
13
Fertilization

• When the egg and sperm cell unite, the egg
  develops a film which prevents more sperm cells
  from entering the egg.
• The fertilized egg travels to the uterus where it
  becomes implanted in the lining.
• The female will not menstruate or ovulate again
  until after the pregnancy is over.

14
Female Health Problems
Yeast Infection
Vaginitis
Toxic shock syndrome(TSS)
Cancer
Sterility
15
Caring for the Female Reproductive System

• Do a breast self-examination every month.
• Shower or bathe daily.
• Keep track of your menstrual cycle.
• See a doctor if a menstrual cycle is missed for
  several months, or if there is severe pain or a
  heavy menstrual flow.

16
Caring for the Female Reproductive System

• See a health care provider if you experience
  premenstrual syndrome (PMS).
• PMS occurs just before menstruation.
• PMS can include headaches, breast tenderness,
  fatigue, irritability, acne, and abdominal cramps.

17
Caring for the Female Reproductive System

• Visit a gynecologist for regular checkups.
