Sexual dimorphism is the differences between males and females in size, appearance and some other characteristics. Sexual dimorphism in humans is greater than in some animals and less than in many. Evolutionary psychologists and biologists are intrigued to understand the function of sexual dimorphism. Depression is twice as common in women as in men, but the reason for this sexual dimorphism is unknown.

Snips and Snails
and Theorists' Tales: Classical Sociological Theory and the Making of 'Sex' -
Exploring how the emerging discipline of sociology both drew on and contributed
to the construction of a scientifically grounded sexual dimorphism.
Barbara L. Marshall, Trent University, Canada.
This article locates classical sociology within the context of widely circulating scientific 'truths' about sexed bodies, exploring how the emerging discipline of sociology both drew on and contributed to the construction of a scientifically grounded sexual dimorphism.
Through an examination of Durkheim's theory of conjugal society and Weber's writings on the routinization of sexual conduct, the extent to which anxieties about masculine sexuality animated classical conceptions of the shifting mind/body relationship in modernity is illuminated.

The etiology and consistency of findings on normal sexual dimorphisms of the adult human brain are unresolved. In this study, we present a comprehensive evaluation of normal sexual dimorphisms of cortical and subcortical brain regions, using in vivo magnetic resonance imaging, in a community sample of 48 normal adults. Sexual dimorphisms of adult brain volumes were more evident in the cortex, with women having larger volumes, relative to cerebrum size, particularly in frontal and medial paralimbic cortices. These findings have implications for developmental studies that would directly test hypotheses about mechanisms relating sex steroid hormones to sexual dimorphisms in humans.

Haqq, Christopher M., and Patricia K. Donahoe. Regulation of Sexual Dimorphism in Mammals. Physiol. Rev. 78: 1-33, 1998. Sexual dimorphism in humans has been the subject of wonder for centuries. In 355 BC, Aristotle postulated that sexual dimorphism arose from differences in the heat of semen at the time of copulation.

Abstract: After antecedent hypoglycemia, counterregulatory responses to subsequent hypoglycemia exhibit greater blunting in men than in women. Because physical exercise and hypoglycemia share multiple counterregulatory mechanisms, we hypothesized that prior exercise may also result in gender-specific blunting of counterregulatory responses to subsequent hypoglycemia.

Childhood Sexual Abuse as a Risk Factor for Depression in Women: Psychosocial and Neurobiological Correlates
Erica L. Weiss, M.D., James G. Longhurst, M.D. and Carolyn M. Mazure, Ph.D.
OBJECTIVE: Depression is twice as common in women as in men, but the reason for this sexual dimorphism is unknown. This article reviews recent studies of the role of childhood sexual abuse in the subsequent development of major depressive disorder, and the biological and psychosocial mechanisms by which early stressors may contribute to adult-onset depression in women. Particular attention is paid to investigations of the long-term effects of early stress on hypothalamic-pituitary-adrenal (HPA) axis function.
