What is the purpose of the reproductive system????
It is a group of organs that make possible the
production of offspring.
A new human life results from the union of two specialized
sex cells (gametes), one from a male and the other from a
female.

What does the female reproductive system do?
It works to make eggs and provide a place to support and
nourish a developing human.
Let’s look closer.
Egg cell
Label your diagram.
They are the female reproductive organs that produce eggs
- Egg cells (ova): sex cells that are produced by the
ovaries and can be fertilized by sperm
- all of the eggs (early versions) a female will ever
have, are in her ovaries when she is born (about 2
million)
- 1 egg (usually) is released each month from one of
the ovaries.
- largest cell in the body- can be seen with the naked
eye.
They make the hormones estrogen and progesterone
- regulate monthly release of an egg and prepare the
body for pregnancy
 Female reproductive organ that provides a place to
support a developing human. Also called the womb.
 Muscular cavity the size of a fist
 The female reproductive organs that transport an egg
from the ovary to the uterus
 Around 10 cm long
 The female reproductive organ that connects the
outside of the body to the uterus
 It’s the pathway that a baby takes out of a woman's
body during childbirth, sometimes called the birth canal
 Receives sperm/semen during reproduction
 The lower portion of the uterus
 It widens during childbirth to allow the baby the exit
 Menstrual fluid flows from the uterus through it
The bladder stores the urine which is produced by the
kidneys.
• Is a tube carries urine from the bladder to the outside
of the body.
A monthly series of hormone-controlled changes that
prepare the uterine lining for a pregnancy.
OvulationThe release of an egg from a follicle in the ovary.
- high levels of estrogen and progesterone thicken
and maintain the uterine lining
- if pregnancy does not occur – estrogen and
progesterone level quickly fall
YOUR PERIOD
Lining of uterus sheds if
there is no fertilization.
Lining of the uterus ready to receive the
embryo.
If egg is fertilized by sperm, embryo
travels to the uterus.
Days of the Average
Menstrual Cycle
Lining of uterus begins
to thicken in
preparation to nourish
a fertilized egg
OVULATION
One egg released
Fertilization is the joining of a male and female
reproductive cell to make the first cell of a new human.
This cell, the fertilized egg, then moves down the fallopian
tube and into the uterus. This can take up to 7 days.
The fertilized egg attaches to the wall of the uterus and
begins to grow.
Females can experience both minor and serious problems
with their reproductive systems.
 Premenstrual Syndrome (PMS)
 Toxic Shock Syndrome - rare but serious bacterial infection associated with
incorrect use of menstrual hygiene products. Can cause a rash and fever. Requires immediate care.
 Infertility - Caused by blocked fallopian tubes or failure to produce eggs.
 Ovarian Cysts - growths on the ovary. Any pain, swelling, abnormal bloating, or heaviness
in the abdominal region should be evaluated
 STI’s
 Cancer - can effect breasts, ovaries, uterus, or cervix
Females should have regular checkups by a physician and
take good care of their reproductive system.
 Monthly breast exams
 Shower regularly
 Record the menstrual periods
 Practice abstinence
What does the male reproductive system do?
It works to produce sperm and deliver it to the female
reproductive system.
Let’s look closer.
Label your diagram.
The skin covered sac that hangs from the body, below the
penis. It holds the testes and epididymis.
− Small muscles in the scrotum move the testes closer or
farther from the body to help regulate temperature of
sperm (if too hot they can become defective).
− Optimal temperature is about 96 degrees.
The male reproductive organs that make
1. sperm
2. the male hormone testosterone
- Two testes rest in the scrotum
- Starting a puberty, several hundred million sperm each
day is produced
- Each sperm is extremely small about 1/600 of an inch
- A human egg is about 30 times bigger
The bladder stores the urine which is produced by the
kidneys.
The male reproductive organ that removes urine from the male’s
body and that can deliver sperm to the female reproductive
system.
• Made of soft spongy tissue and blood vessels
• Erections - it becomes erect or firm due to blood flow into the
tissues (7-12 a day can happen during puberty)
• Ejaculation - occurs when semen is released from the penis
• Nocturnal emissions – release of semen (the fluid containing
sperm) is discharged from the penis during ejaculation while a
guy's asleep
• It is a very tightly coiled tube where sperm mature (about 3
weeks) and are stored.
• Sperm stay there until needed (erection).
• After about 48 hours, the old ones are
reabsorbed into the body.
• They are composed of three primary regions, consisting of a head, a
midpiece, and a tail.
• The head contains genetic material and is also designed to let it penetrate the
female egg,
• the midpiece is home to the organelles which allow energy (fuel) production
within the sperm.
• The tail’s primarily functional is for locomotion (movement)
• A long, muscular tube
• It transports mature sperm to the urethra
in preparations for ejaculation.
• A gland in males that adds fluids that nourish and
protect sperm from the acid in the female reproductive
system
 Produce thick secretions that nourish the sperm and
help sperm move easier
 Found the base of the urinary bladder
• Is a tube that passes through the penis. It carries urine
from the bladder to the outside of the body.
• Sperm/semen leave the body during ejaculation from
this tube
A mixture of sperm and other secretions from the male reproductive organ.
(65% fluid is produced by the seminal vesicles, 30% by the prostate, 5% sperm from the
testicles and epididymis)
( last page of notes )
Males can experience both minor and serious problems with their
reproductive systems:
o Sterility-
not producing enough healthy sperm to have kids
o Enlarged prostate gland -
associated with aging
o STI’s - Infections spread by sexual contact
o Cancer - can affect testicles, prostate, other male reproductive organs
Males should:
 Practice self- exam - of scrotum and testicles once a month to check
for lumps or unusual swelling
 Shower/bathe regularly
 Wear a protective cup or supporter during athletic
activities - to prevent accidental injuries
