Problem
Two years ago, she was jogging about 20 miles per week. However, she had not done any running for the past year because she "didn't feel up to it" and complained of general muscle weakness. She said she often felt irritable and had mood swings. Her menstrual periods have been less frequent over the past year. Her previous medical history was normal for a person her age. She states that she has double vision when looking to the side but does not have any loss of vision when using only one eye or the other. Reflect and Review #2
I. Which hypothalamic, anterior pituitary gland, and ovarian hormones control the menstrual cycle?
II. What anterior pituitary gland disorder can cause a decrease in menstrual cycle frequency and loss of vision?
