FSH (follicle stimulating hormone)
The production of sperm takes place in the _______________. These paired glands are contained in a sac
called the _______________.
_______________.
The sperm travel to the urethra through a long tube called the
During this passage, _______________, secreted by the _______________,
_______________ and Cowper’s glands are mixed with the sperm.
_______________.
This mixture is called
During sexual intercourse, _______________ is released through the urethra and
deposited in the female’s_______________. The female gonad is called the _______________. A female is
born with all the egg cells, or _______________, that she will ever have, but they are immature. Beginning
at _______________, the hormone_______________ is released from the pituitary gland to stimulate
maturation of eggs. The eggs are contained in saclike structures called_______________. Usually, only one
of the eggs matures fully each month.
As the _______________ enlarge, they secrete the hormone
_______________, which causes the lining of the _______________ to thicken. After about 9 to 19 days, a
surge of the hormone _______________ is released from the pituitary. This causes the fully developed
_______________ to rupture, releasing a mature egg. This is called _______________. The empty follicle
now becomes a mass of yellow tissue called the _______________.
This secretes the hormone
_______________ which further thickens the lining of the uterus in preparation for receiving and nourishing
a fertilized egg. When the ovum is released during _______________, it enters a _______________ and
begins its journey to the uterus. If it encounters sperm during this journey, it may be fertilized and begin
dividing. When the fertilized egg reaches the uterus, if all goes well, _______________ will occur and a
pregnancy will be established. If no fertilization occurs, the _______________ disintegrates in 13-15 days
and _______________ occurs. Then the cycle begins again.

b. Placenta
c. Fallopian tube
d. Uterine wall
e. Umbilical cord

Fill in the blanks with correct answers:
After two months of development, the embryo is called a (an) _______________. The _______________ is
formed in part from the inner lining of the uterus and in part from other membranes. It is through the
placenta that the embryo/fetus is nourished while in the _______________ and _______________ are carried
away. The _______________ connects the embryo/fetus with the placenta. It provides a transport system
for placental-fetal circulation. The _______________ is the innermost of the extra embryonic membranes,
and it forms a fluid-filled _______________, around the embryo/fetus.
