Male and FemaleReproductive
Systems
Sperm – the sex cells that are made by males and that are needed to fertilize eggs.
Testes – the male reproductive organs that produce sperm and testosterone.
Scrotum – the skin covered sac that surround the testes.
Epididymis – once sperm are made
they move into this coiled tube
Vas Deferens – once a sperm matures, it travels
into this tube
Prostate Gland –
the male gland
that adds fluid to
the sperm to
nourish and protect it.
sperm and the added fluids
the tube that passes through the penis. Sperm leave the body during ejaculation via this tube
the organ that removes
urine from the male body
and that can deliver sperm
to the female
reproductive
system
the male hormone made by the testes.
What is the function of each part?
the head contains substances that help the sperm enter the egg.
the mid piece (body) contains structures that
release the energy needed for the long
trip through the female reproductive system.
the tail is made of proteins that help the sperm move.
How long does it
take an immature
sperm to mature?
An immature sperm takes 2 – 10 days
to fully mature.
~ seminal vesicle
~ bulbourethral glands (Cowpers glands)
~ prostate gland
What 3 organs add fluid
to the sperm?
What prevents urine
and semen from going
through the penis
at the same time?
A flap in the urethra
What are some signs that a male is going through puberty?
Shoulders get wider
& develop muscles
hair grows on the face and other body parts
voice deepens
At this time testosterone also causes the body to start
making sperm.
the sex cells of females that can be fertilized
by sperm
the female reproductive organs that produce eggs and hormones
connects the ovary to the
uterus
the muscular organ the size of a fist where fertilized eggs develop.
the narrow base of the uterus
the lining of the uterus that thickens as an egg matures
a blood vessel-rich
tissue that forms in a mother’s uterus
reproductive organ that connects the uterus to the outside of the body.
If an egg is not fertilized, the blood vessels in the endometrium break down.
The process in which the blood and tissue that built up in the uterus flows
out of the body through the vagina.
a monthly series of hormone-controlled
changes that mature an egg and prepare the uterus for pregnancy.

What are the two
female hormones
our body produces?
Girls have all their eggs at

When do eggs mature?
Eggs begin to mature when a girl reaches puberty
How often do eggs mature?
One egg matures every 28 days

In the fallopian tubes
What happens to the egg if it is not fertilized?
If it is not fertilized the blood vessels in
the endometrium

vagina in your monthly
menstrual cycle.
