The body system containing the organs that make
possible the production of offspring

• reproductivesystem

The male sex cell

• sperm

When an internal organ pushes against or through
a surrounding cavity wall

• hernia

When a males sperm cell joins with a females
egg cell

• fertilization

3
The release of one mature egg cell each month

• ovulation

When the lining material, the unfertilized egg,
and some blood flow out of the body

• menstruation

Hormonal changes that occur in females from the
beginning of one menstruation to the next

• menstrualcycle

4
Comparing and Contrasting Make a list of
similarities and differences between the male and
female reproductive systems.
5

• In this lesson, you will learn to
• identify the parts of the male and female
  reproductive systems.
• explain the three functions of the female
  reproductive system.
• identify problems of the male and female
  reproductive systems.
• describe ways to keep your reproductive system
  healthy.

6
The Reproductive System

• Unlike other body systems, the reproductive
  system is different for males and females.

the organs that make possible the production of
offspring
7
The Male Reproductive System

• During puberty, the testes produce testosterone
  and sperm.

sperm The male sex cell
8
The Male Reproductive System
Epididymis
Van Deferens
Ejaculation
Sperm mix with secretions from the seminal
vesicles, the prostrate gland, and the Cowpers
gland. Semen is created.
9
Problems of the Male Reproductive System
Injury to the testes
Testicular cancer
Hernia
Sexually transmitteddiseases (STDs)
hernia When an internal organ pushes against or
through a surrounding cavity wall
10
The Female Reproductive System
Three Functions of the Female Reproductive System
Store egg cells
Create offspring
Give birth
11
The Female Reproductive System

• New life is formed through the process of
  fertilization.

fertilization When a males sperm cell joins
with a female egg
Once fertilized, the egg travels from the
fallopian tube to the uterus where it attaches to
the wall of the uterus and begins to grow.
12
The Female Reproductive System

• The embryo becomes a fetus in about eight weeks.
• In approximately nine months, the fetus is mature
  and ready to be born.

13
The Menstrual Cycle

• During puberty, egg cells mature and are released
  by the ovaries in a process called ovulation.

ovulation The release of one mature egg cell
each month
14
The Menstrual Cycle

• If an egg is not fertilized, the uterus lining
  breaks down and is shed by the body through
  menstruation.

menstruation When the lining material, the
unfertilized egg, and some blood flow out of the
body
15
The Menstrual Cycle

• Menstruation usually lasts from 5 to 7 days and
  happens about every 28 days.
• This process is called the menstrual cycle.

females from the beginning of one menstruation
to the next
16
Problems of the Female Reproductive System
Infertility
Ovarian cysts
Sexually Transmitted Diseases (STDs)
17
Care of the Reproductive System
Males
Females

• Avoid wearing tight clothing.
• Check the testes monthly for lumps, swelling, or
  soreness.

• Perform a breast self-exam monthly for unusual
  lumps or thickening.
• Get regular physical exams.
• Keep a record of the menstrual cycle.
• During the period, change tampons or sanitary
  pads every four hours.
• See a doctor if you experience severe cramps or
  unusually heavy bleeding.

Both

• Practice good hygiene by bathing or showering
  regularly.
• Abstain from sexual activity, which will protect
  you from STDs and unplanned pregnancy.
