'SEX and the FEMALE BRAIN are CONNECTED' - shock discovery
In a discovery sure to stir intense discussion, scientists in Canada say they have discovered a powerful chemical signal embedded in semen which acts directly upon the brains of female mammals - apparently including humans.
In a just-released announcement arrestingly headlined "Team unlocks link between sex and the female brain", spokespersons at Saskatchewan uni in Canada lay out the groundbreaking boffinry.
It appears that scientists had for long known of a protein, dubbed ovulation-inducing factor (OIF), that is found in the semen of all species of mammal analysed to date including humans. In some species this chemical's effects are powerful indeed, causing a female to ovulate upon being inseminated. Human females aren't among this group, instead being among those known to science as "spontaneous ovulators", who release eggs to their own schedule.
Meanwhile another powerful chemical was also well known to science - nerve growth factor (NGF), which has a powerful effect in all mammals on all nervous tissues including those of the brain.
So apparently men really do something to our nerves.
