Answer to Question 1

ANS: A
The natural estrogenic hormone released from the ovaries comprises several closely related chemical compounds: estradiol, estrone, and estriol. The most potent is estradiol.
Estradiol is metabolized to estrone, which is half as potent. Estrone is metabolized to estriol, which is considerably less potent. Estrogens are a group of steroid compounds named for their importance in the estrus cycle, functioning as the primary female sex hormone.

Answer to Question 2

ANS: D
When androgens are used for palliation of breast cancer in women, they suppress cancer cell growth. Androgens affect muscle growth, not fat stores. Estrogen affects fat stores. Although androgens may be used to stimulate appetite and improve nutrition, this is not the indication in this case. Although androgens may be used to prevent wasting, this is not the indication in this case.
