Sexual motivation is influenced by hormones such as testosteroneestrogenprogesteroneoxytocinand vasopressin. In most mammalian species, sex hormones control the ability to engage in sexual behaviors. However, sex hormones do not directly regulate the ability to copulate in primates including humans.
A hormone is something produced in the body that circulates in the bloodstream and then influences the activity of living cells that are far from where it was produced. Because hormones travel to their target tissue, they are sometimes referred to as signaling molecules. For example, estrogen is produced by the ovaries, but effects the functioning of cells in the heart, uterus, breast, liver, and brain.
The goal of this module is to introduce you to the topic of hormones and behavior. This field of study is also called behavioral endocrinology, which is the scientific study of the interaction between hormones and behavior. This interaction is bidirectional: hormones can influence behavior, and behavior can sometimes influence hormone concentrations.
Women who seek medical care around the time of menopause frequently report changes in one or more aspects of psychological functioning. The etiology of these symptoms is likely multifactorial and, undoubtedly, individual and sociocultural factors are important determinants. The known psychotropic properties of the sex hormones provide reason to believe that the drastic decrease in sex steroid production at menopause is also causally related to the development of psychological symptoms in some women.

Besides their key role in reproduction, estrogens have effects in several organs in the body, as confirmed by the identification of estrogen receptors ER in multiple tissues. Experimental evidence has shown that estrogens have significant impacts on the central nervous system CNSand a key question is to what extent the fall in estrogen levels in the blood that occurs with increasing age, particularly around and following the menopause, has an impact on the cognitive function and psychological health of women, specifically regarding mood. This review will consider direct effects of menopausal changes in estrogens on the brain, including cognitive function and mood.
Behavior Genetics. This paper presents both a review of empirical studies regarding the interacting effects of sex hormones and socialization on cognitive style in rats and men and a new experimental study of the effects of sex hormones on the white rat. In a study of West African males feminized by a kwashiorkor-induced endocrine dysfunction, it was found that males presenting the gynecomastia symptom had a significantly more feminine cognitive style than control males—the former subjects having lower spatial ability, being more field dependent, with higher verbal and lower numerical ability, and having significantly more feminine scores on two measures of sexual bias than the controls. Evidence is also presented to show that in cases of testicular feminization, Turner's syndrome, and Klinefelter's syndrome—even where the sex of rearing is opposite to the genetic sex—the subjects develop cognitive abilities in line with sex of rearing and socialization.
