Male and Female
Reproductive
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
surrounds 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.
Semen –
sperm and the added fluids.
Urethra - the tube that passes
through the penis. Sperm leave the
body during ejaculation via this tube.
Penis - the organ that
removes urine from the male body
and that can deliver sperm
to the female
reproductive
system.
Testosterone - the male
hormone made by the testes.
How long does it take
an immature sperm to
mature?
An immature sperm
takes 2 – 10 days
to fully mature.
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.
Eggs - the sex cells of females
that can be fertilized
by sperm.
Ovaries –
the female
reproductive
organs that produce
eggs and hormones.
Fallopian Tubes – connect the
ovaries to the uterus.
Uterus – the muscular organ the
size of a fist where fertilized eggs
develop.
Cervix - the narrow base
of the uterus.
Endometrium – the lining of the
uterus that thickens as an egg
matures.
Placenta - a blood vessel-rich
tissue that forms in a mother’s
uterus.
Vagina - 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 some signs that a
female is going through puberty?
Growth of hair under the arms and pubic region
Increase in height & weight
Growth of darker hair on the legs
Increase in perspiration
Widening of the hips
Increase in breast size

hormones our body produces?

On average, how many are there?
Over 2 Million
When do eggs mature?
