Chapter 9, Problem 26CAQ
Shannon, a 28-year-old, has been in the first stage of labor for 15 hours. Her uterine contractions are weak, and her labor is not progressing normally. Shannon and her doctor desire a vaginal delivery, so the physician orders that Pitocin (a synthetic oxytocin) be infused. What is the effect of this hormone?

A 38-year-old male is upset about his low sperm count and visits a "practitioner" who commonly advertises his miracle cures of sterility. The practitioner is a quack who treats conditions of low sperm count with megadoses of testosterone. Although his patients experience a huge surge in libido, their sperm count is even lower after hormone treatment.
a) Which two glands would be responsive to the megadose of testosterone?
b) Identify the two hormones that would be affected by the megadose of testosterone. Would their levels increase or decrease?
c) What role, if any, would either of the affected hormones have on the man's reduced sperm count?
You are an intern working with a research endocrinologist at the University of Alberta. Currently, you are part of a research team that is trying to determine the cause of the premature onset of menopause in women living in Alberta. For your project, you need to submit a proposal as to how you would determine the point during the menstrual cycle when a woman is most fertile. In order to do this, you musta) Identify the main hormone involved. b) Identify the most fertile day(s) for women. c.) Describe the method you would use to determine the exact fertile days for each participant. Remember that all experiments require controls and baselines for measuring.
Select the correct statement regarding ACTH?
A) it is an amino acid-based hormone
B) it is produced and released by the posterior pituitary gland
D) it causes the the release of hormones from the ovaries
