Explain two reasons why a woman with low levels of LH would not be able to become
pregnant.
ANSWER ✔✔
1. LH acts on the ovary to cause ovulation to occur.
2. LH causes progesterone release to facilitate potential fertilization of the egg and
pregnancy. Progesterone is a key hormone for the maintenance of pregnancy.
Would you expect a female to have testosterone in their bloodstream? Explain why or why
not.
ANSWER ✔✔
1. Yes. Both male and female bodies produce "all" the sex hormones. However, the ratios
are different.
2. The adrenal glands are largely responsible for producing this "opposite" hormone that the
ovaries would not.

Explain the concept of negative feedback and how it helps to maintain homeostasis.
ANSWER ✔✔
1. The effect or increased level of the hormone acts to shut down the continued release of
the hormone.
2. The brain is constantly monitoring hormone levels to keep levels within a certain range or
set-point (homeostasis). Negative feedback is a way of "turning off" hormone production
when the desired level is achieved.
Explain the concept of positive feedback. Give an example of a hormone that works
through positive feedback.
ANSWER ✔✔
1. Positive feedback is the action of a hormone increasing the production of that hormone.
(This is the opposite of negative feedback).
2. One example is the action of oxytocin causing the uterus to contract during labor.
Oxytocin enhances the effect of the uterus contractions, causing more oxytocin to be
released. The positive feedback loop is stopped once the baby is born and the uterus no
longer needs to contract, stopping the production of oxytocin.
This type of hormone is derived from cholesterol:
A. Peptide hormones
B. Catecholamines
C. Steroid hormones
D. Tyrosine
ANSWER ✔✔
C: Steroid hormones
