Describe the organizing effects of sex hormones and give specific examples.
What will be an ideal response?
Organizing effects produce long-lasting structural effects. During a sensitive period in early development, the first trimester of pregnancy for humans, sex hormones determine whether the body develops female or male genitals. They lead to more receptors, and therefore greater sensitivity, around the female nipples than the male nipples. Later researchers recognized that sex hormones produce additional organizing effects at puberty. The surge of hormones at puberty produces breast development in women, facial hair and penis growth in men, changes in voice, and male-female differences in the anatomy of certain parts of the hypothalamus. Some of the differences in brain anatomy between males and females increase during this time. The changes developing at puberty persist throughout life, even after the concentration of sex hormones declines.

Suppose that Chris and David are both happily married, but that Chris tends to look at other women—attractive single women who are potential alternative prospects—when he is out on the town at bars and clubs. Does this mean that Chris's marriage is less likely to last than David's?
a. Yes—research suggests that the more time people spend looking at alternative prospects, the more likely it is that their relationship is doomed. b. No—the degree to which people look at alternative prospects does not appear to be related to relationship success. c. No—in fact, people who look at alternatives at least occasionally are MORE likely to have successful relationships than people who don't. d.
