hormone testosterone, is where sperm are
produced.
Located in scrotum to minimize heat.
Testosterone controls male development.

Sperm mixes with semen to provide an
environment to swim. Semen also provides
nutrients for sperm.
Semen travel down urethra which travel through
the penis. Muscle contraction prevent urine and
semen from mixing.
Female Reproductive System
 Specialized to produce eggs (in ovaries) and
nourish a developing baby until birth. Produces
estrogen and other hormones for development.
 Each month one ovary releases a mature egg
(menstruation) down the fallopian tube.
Fertilization, the joining of egg and sperm, occurs
in the fallopian tube.
 Egg travels to uterus, a hollow, muscular organ
where egg attaches. If unfertilized, egg breaks
down (menstruation).
 Vagina or birth canal is where the baby leaves
mother during childbirth.
