Sex differences in immunity in two species of field crickets

Immune defense often differs between the sexes, with males often having a weaker response, at least among many vertebrates. We examined encapsulation ability, a cell-mediated immune response, in laboratory and field populations of two species of field crickets, Teleogryllus oceanicus (Le Guillou, 1841) and Teleogryllus commodus (Walker, 1869), which have different life histories. In the seasona...

Social interactions unmask sex differences in humoral immunity in voles.

Sex differences in immune function are well established among laboratory rodents, with males typically having lower immunity than females. This sex difference may reflect the suppressive effects of testosterone on immune function. Because polygynous males generally have higher circulating testosterone concentrations than monogamous males, sex differences in immune function are hypothesized to b...

Research which asserts that there is a difference in male and female intelligence causes as much of a stir as that which shows the differences in race IQs. However, it is the differences in intelligence of the sexes which is far more controversial among experts, with approximately half of the studies finding no difference, and half finding a small male advantage. A meta-study of 26 articles tha...
