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 –

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.
An immature sperm takes
2 – 10 days
to fully mature.
