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

What is the function of each part?
![Page 10: 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](https://reader035.vdocuments.mx/reader035/viewer/2022062300/56649f4e5503460f94c6fdd6/html5/thumbnails/10.jpg)
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.

to the sperm?

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.

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.

What are the two
female hormones
our body produces?
Girls have all their eggs at
birth. On average, how
many are there?

When do eggs mature?
Eggs begin to mature when a girl reaches puberty
How often do eggs mature?
One egg matures every 28 days
Where are eggs fertilized?
In the fallopian tubes
![Page 40: 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](https://reader035.vdocuments.mx/reader035/viewer/2022062300/56649f4e5503460f94c6fdd6/html5/thumbnails/40.jpg)
What happens to the egg if it is not fertilized?
If it is not fertilized the blood vessels in
the endometrium
break down and the body gets rid of it through the
vagina in your monthly
menstrual cycle.
