Our results suggest that this atypical pattern may be due to the combination of sex-specific life history challenges encountered by females, such as blood feeding.
Furthermore, female propensity to mate only once in nature in male swarms likely diminishes sexual selection of post-reproductive traits related to sperm competition among males.
Understanding how phenotypic differences between males and females arise from the sex-biased expression of nearly identical genomes can reveal important insights into the biology and evolution of a species.
Among mosquito species, these phenotypic differences include vectorial capacity, as it is only females that blood feed and thus transmit human malaria.
In view of the fact that psychoanalysts still have to deal with a great deal of this kind of impotence today, when the taboos are much weaker than they were in the Middle Ages, it is just possible that psychic impotence may have been growing so widespread as to become a real threat to human fertility.
