Lab 3.7: Juliet’s Fertility Cycle
Once again, the functioning of one’s body is a locus of profound
personal meaning. It makes sense to relate new science learning
On the other hand, such a point of personally meaningful
experience is very sensitive to rough or crude treatment from
others, especially in the presence of the opposite sex. If this is to
be a positive learning experience for everyone, then everyone
must be held to a high standard of sensitivity for the feelings of
The quantities of hormone in the exercise are provided as
“percentages of a median maximum level” for many women. In
fact, the concentration of each hormone in micrograms per litre
are very different. In general, only very tiny amounts of FSH
and LH are needed to affect the changes in the follicle. The
changing follicle, in turn, produces tens and hundreds of times
greater concentrations of estrogen and progesterone.
The list of emotional and physical changes during the fertility
cycle are gathered from a number of sources. Not every woman
experiences every change. There is much less data on the male
fertility cycle. It is a daily cycle, and the physiological and
emotional changes are not readily separated from other daily
Each graph is related to its effects in the fertility cycle.

Act. 3.7: Juliet’s Fertility Cycle
What’s The Question?
Like every other young woman, Juliet’s body
undergoes a cycle every month. This delicate, complex series of
changes prepare her body to conceive and carry a healthy baby to term.
What Are We Doing?
There are four sex hormones circulating in Juliet’s bloodstream.
Each hormone level rises and falls at certain times during her
cycle. On the table at left are daily measurements of Juliet’s
Use a pencil to plot the values of each hormone on the graphs at
the back. Be very careful to check that you are putting the data in
Connect the points with a smooth curve.
What Are We Thinking About?
Follicle Stimulating Hormone (FSH) causes one follicle to grow.
As it grows, it produces Estrogen, and eventually release an ovum.
Luteinizing Hormone LH changes the follicle into a white body
Estrogen generally increases fertility and prepares the body for
Progesterone maintains the body’s state of readiness for pregnancy.
When the body is no longer prepared to become pregnant, and the
lining of the uterus is shed in the menstrual period.
Questions For Later. .
Once the ovum is released, it only lives for a few hours. If Juliet is
going to have a baby, when must Romeo’s sperm cells be present?
Juliet is much more than a collection of hormones. Her whole
person is involved in this remarkable cycle. List some ways that
Romeo could demonstrate respect for Juliet’s whole person.
