Male Reproductive Vocab
• Sperm – male reproductive cells
• Testes – male reproductive glands
• Testosterone – male sex hormone, affects
the production of sperm
_____4______
The prostate gland adds a fluid that protects the
sperm.
_____2______
Sperm travel through the vas deferens to the seminal
vesicle.
______1_____
Sperm are produced in the testes. They mature and are stored
in the epididymis.
_____3______
Seminal vesicles add a fluid that provides a source of energy
for the active sperm.
____5_______
The bulbourethral glands add a fluid that protects sperm from
the acidic conditions in the urethra.

Important Facts:
• Because they are located outside of the body, the
temperature of the testes is a few degrees lower then
the rest of the body. Sperm need this lower
temperature to develop properly and survive.
• Several million (40-600 million) sperm are released
during one ejaculation. It take ONE to fertilize an egg.
• Caring for the male reproductive system involves
cleanliness, sexual abstinence, protection from
trauma, self-exams, and regular medical checkups
Female Reproductive System
The functions of the female reproductive system are to
produce sex hormones, to produce eggs, and to
provide a nourishing environment in which a fertilized
egg can develop into a baby.

The Menstrual Cycle
•During the menstrual cycle, an ovary releases a mature
egg. The egg travels to the uterus. If the egg is not
fertilized, the uterine lining is shed and a new cycle
begins
•Caring for the female reproductive system involves
cleanliness, sexual abstinence, prompt treatment for
infections, self-exams, and regular medical checkups.
•Once a female has reached puberty, it is recommended to
have a yearly check up by a gynecologist.
•During the yearly exam the doctor will perform a Pap
smear, this is when a sample of cells is taken from the
cervix.
Female Reproductive Vocab
• Ova – the female reproductive cells, eggs
• Ovaries – reproductive glands in which
eggs are produced
• Estrogen – female sex hormone that
activates physical changes at puberty
• Progesterone – activates changes in women
before and during pregnancy
• Ovulation – ripened egg is released once a
month
