Sex differences, sex ratios and sex roles
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1994Sexual selection theory predicts that sex roles will be determined by the operational sex ratio (OSR), the sex ratio among individuals searching for mates at any given time. There are two predictions: (i) the sex which is in 'excess' will be the more competitive sex with respect to access to mates; and (ii) the sex of which there is a 'shortage' will ...

Annals of the New York Academy of Sciences, 2000Abstract: Sex differences in social behavior are center stage in recent formulations of evolutionary psychology. Evolutionary psychology, with its emphasis on the long‐term consequences of early adaptations, offers itself as an alternative meta‐theory to mainstream social psychology, which emphasizes the importance of social structures in determining ...

Infection with the protozoan parasite Entamoeba histolytica is much more likely to cause severe, focal liver damage in males than females, although the infection rate is the same in both sexes. The differences in disease susceptibility may be due to modulation of key mechanisms of the innate immune response by sex hormones.

Females greatly outnumber males as sufferers of chronic pain. Although social and psychological factors certainly play a role in the differences in prevalence and incidence, biological differences in the functioning of the immune system likely underlie these observed effects.

Although women live longer lives than men, they tend to have poorer health status. Here, we review the biological and socio-behavioral factors that may contribute to this sex-frailty paradox. The conceptual framework that frailty is a product of the environment and the recovery rate provides a new understanding of women's frailty burden. Even developed

Sex Differences in Pharmacokinetics
2023Because women have been excluded from most clinical trials, assessment of sex differences in pharmacokinetics is available for a minority of currently prescribed drugs. In a 2020 analysis, substantial pharmacokinetic (PK) sex differences were established for 86 drugs: women given the same drug dose as men routinely generated higher blood concentrations
