5. The United States has one
of the highest teen
pregnancy rates in the
western industrialized
world!

7. Pair/Share
Why do teenagers get pregnant?

8. Why do teenagers get pregnant?
• not thinking
• getting caught up in the moment -hormones
• believing they couldn’t get pregnant
• being drunk
• feeling pressured to have unprotected sex
• being too embarrassed to ask a partner to
use contraception
• curiosity
• think everyone else is “doing it”
• culture: tells us the decision to have sex is
NOT a big deal…it is a BIG deal

9. • 3 in 10 teen American girls will get
pregnant at least once before age 20.
That’s nearly 750,000 teen pregnancies
every year.
• Parenthood is the leading reason that teen
girls drop out of school. More than 50% of
teen mothers never graduate from high
school.
• About 25% of teen moms have a 2nd child
within 24 months of their first baby.
• Less than 2% of teen moms earn a college
degree by age 30.

10.  How do the male and female
reproductive systems differ?
• Males have external organs, females
have internal organs
• Male sperm production begins at
puberty, females are born with ova
• Males produce millions of sperm,
females release one ovum each month

12. Facts about the reproductive systems…
Size of sex cells:
– Female ovum =
1/175th inch
– Male sperm =
500 lined up
tail to tail
would
equal one inch

13. Production of sex cells
Females are born with 200,000 –
400,000 immature ova. Approximately
375 will be released in a lifetime!
One spoonful of semen can contain 100
million – 300 million sperm!

14. Sperm
• Head- contains DNA,
which when combined
with the egg's DNA,
will create a new
individual… tip of sperm
head is called the
acrosome, which
enables the sperm to
penetrate the egg.
• Midpiece- contains
mitochondria which
supplies the energy the
tail needs to move.
• Tail- moves with whip-
like movements back
and forth to propel the
sperm towards the egg.

15. The Endocrine System regulates long term changes in your body like
growth and development. It also controls many of your body’s daily
activities.
A hormone is a chemical substance produced by an endocrine gland.
Puberty is a period of sexual development during which a person
becomes sexually mature and physically able to reproduce.

22. ADDITIONAL TERMS TO KNOW
• Sperm: male reproductive cells
• Testosterone: hormone that
produces male secondary sex
characteristics
• Semen: thick fluid that contains
sperm and secretions from male
reproductive organs
• Erection: penis swells with blood and
elongates

23. • Ejaculation: release of semen from
the penis as a result of muscular
contractions
• Nocturnal emission (wet dreams): an
involuntary discharge of semen during
sleep

24. Circumcision:
foreskin is
removed
surgically
after birth

25. Male Reproductive System Class Activity:
Held in the scrotum, …….
A valve within the urethra prevents the two
fluids from mixing. Several million sperm
are released during one ejaculation.

26. Held in the scrotum, are two testicles, where millions of sperm cells are
produced.
The undeveloped sperm cells move to the epididymus where they mature.
During sexual excitement, blood fills up the erectile tissue of the penis,
causing an erection. Sperm then travel through the vas deferens.
When ejaculation occurs,
sperm cells mix with fluid from the seminal vesicles and the prostate
gland.
The mixture of sperm cells and seminal fluid is called semen.
Semen is then forced through the urethra.
The urethra carries urine as well as semen to the outside of the body,
but not at the same time.
A valve within the urethra prevents the two fluids from mixing.
Several million sperm are released during one ejaculation.

29. Female reproductive system

31. Endometrium
(inside lining)
Ovary
Fallopian Tube
Cervix
Vagina
Uterus –
(outside)

32. A. Ovaries
Reproductive glands; produce ova and
estrogen
B. Fallopian Tubes
Four-inch long tube; connects ovary to
uterus
C. Endometrium
Inner lining of the uterus, thickens to
receive the fertilized egg

33. D. Vagina
Muscular tube to outside of body; organ for
sexual intercourse; birth canal
E. Uterus
Muscular organ; supports fetilized egg during
pregnancy; contracts during childbirth
F. Cervix
Lowest part of the uterus; connects to vagina

34. • Ova: female reproductive cells
• Estrogen / progesterone: hormones
that produce female secondary sex
characteristics
• Ovulation: process of releasing one
mature ovum each month
• Menstration: unfertilized egg and
lining of uterus leave body in
menstrual flow

35. Clitoris - small, highly sensitive
structure located above the opening
to the urethra
Labia minora/Labia majora – folds of
skin covering the opening to the
vagina
Vulva: the outside part of the female
reproductive system

41. Fertility Awareness or “Fertile” Days of a
menstrual cycle:
• Track your period for about 3-4 months.
• Ovulation occurs about 13-14 days before menstruation
begins.
• The egg cell lives anywhere from 12-24 hours.
• The sperm cell can live for 3-5 days inside the female
reproductive system.
• During ovulation, the cervix dilates (opens) and the
cervical mucus thins to promote fertilization

42. 1. Count the number of cycle days – 28.
2. Count backwards 13-14 days.
3. Subtract 5 dates for the longevity of the sperm. Add 1
date for the life cycle of the egg (1 day).

43. The female got her period 2 days late! Instead of October
28th, she got her period on October 30th. When could she
GUESS to be fertile the month of November?

52. There is an app for everything…

53. PMS = Premenstrual Syndrome
• Physical and emotional symptoms a
female experiences prior to getting
her period
• Caused by hormonal changes
• Symptoms include: anxiety, depressed
mood, crying spells, mood swings and
irritability, anger, food cravings,
insomnia, poor concentration

54. Toxic shock syndrome is a rare, life-
threatening complication of bacterial
infection in the blood. Toxic shock
syndrome has been associated with:
• Using superabsorbent tampons
• Wearing a diaphragm or
contraceptive sponge
• Having a staph or strep infection,
especially if you have skin wounds or
healing surgical incisions

55. Symptoms of TSS:
• Fever over 102 F
• vomiting or diarrhea
• A rash resembling a sunburn with
peeling skin, especially on the palms and
soles
• dizziness or mental confusion
• Pale and clammy skin, signaling a rapid drop
in blood pressure; if toxic shock is left
untreated at this stage, it will quickly lead
to loss of consciousness, cardiac and
respiratory failure, and death.

56. Menopause:
permanent end of
menstruation and fertility due
to decreasing levels of
hormones. Usually occurs
around 45-55.

60. Path of sperm through the
male reproductive system
activity
To start:
Held in the scrotum,

61. The uterus is the part of the body that a baby will grow. The inner lining in the
uterus is what supports and nourishes the baby. If fertilization does not occur,
what is shed during a woman’s period? the lining. During a woman’s period,
blood and other tissue from the uterus leave the body through the vagina. A
period can last from a few days to about one week. The average menstrual cycle
is about 28 days. Day 1 of the menstrual cycle is the first day of the period. In
the middle of the menstrual cycle (around day 13-14) the ovary releases an egg.
How many days does it take for an egg to travel down a fallopian tube? a few
days. Meanwhile the lining of the uterus gradually gets thicker so it can
support the development of a fertilized egg. If the egg gets fertilized it will
implant in the endometrium (lining) and the woman is pregnant! If it is not
fertilized, the woman is not pregnant and the egg will begin to dissolve and the
lining is not needed and the cycle begins again.
