One possible explanation for this may be an oestrogen effect during reproductive years increasing the risk of autoimmune disease in women [169]. The age of onset for AQP4 antibody-associated NMOSD ranged from 2 to 86 years and had a mean of 41.7 years (95% CI 38.5–43.8) when only AQP4 ...

Because women are more likely than men to use social status as a criterion in mate selection, evolutionary theory has led to the hypothesis that higher proportions of males will be born to parents of high social status than to parents of low status. To date, the research that has tested th...
