Sexual Dimorphism and Sexual Intermediaries
The American Journal of Bioethics, 2010Robert Sparrow's article (2010) attempts to defend the position that humans are sexually dimorphic. However, human embryology clearly shows this is not the case.

Abstract: An increasing amount of evidences suggests that galanin plays an important role in the regulation of reproduction in the rat. Galanin is colocalized with luteinizing hormone‐releasing hormone (LHRH) in a subset of LHRH neurons, and the pattern of coexpression is sexually dimorphic, with a higher incidence of colocalization and level of ...

Sexual Dimorphism in Autoimmune Disease
Current Molecular Medicine, 2009We briefly survey the concept of autoimmunity and nominate the range of autoimmune diseases that include multisystemic and organ-specific disorders, and cite prevalences of autoimmune diseases in males and females, in humans and in experimental animals.

Two studies have now provided evidence of differences, dependent on patient sex, in oncogenic features, such as frequencies of driver gene mutations, mutation load and mutational signatures, as well as immune selection.

Evolution of Sexual Dimorphism in the Lepidoptera
Annual Review of Entomology, 2011Among the animals, the Lepidoptera (moths and butterflies) are second only to beetles in number of described species and are known for their striking intra- and interspecific diversity. Within species, sexual dimorphism is a source of variation in life history (e.g., sexual size dimorphism and protandry), morphology (e.g., wing shape and color pattern)

Sexual dimorphism of hypertension
Current Opinion in Nephrology and Hypertension, 1996A sexually dimorphic pattern of blood pressure, in which the male develops higher blood pressure than the age-matched female, has been observed both in human subjects and in laboratory animals. The mechanism(s) of this sexual dimorphism of blood pressure are not completely understood.

Summary1. Life expectancy and mortality rates from diseases arising in various organs vary with sex because of differential exposure to external hazards and because of essential differences between males and females in aspects not directly connected with reproduction.

Sex differences in behavior are the result of natural and sexual selection. The dimorphic classes of behavior described here, courtship, copulatory, and parental behaviors, reflect both kinds of evolutionary selective pressures. We can further distinguish two kinds of mechanisms that produce differences in male and female behaviors. In one, both sexes

Stroke is a leading cause of death and serious, long-term disability. Studies evaluating differences between men and women are lacking. Significant differences exist between men and women in terms of risk factors and susceptibility to stroke. Women are less likely to have diagnostic studies performed to evaluate their risk for stroke, and they have a ...
