After comparing the genomes of more than three women, Eyam Bonquers of the Paris Institute for Science and Baloney has found a gene on the X-Chromosome that is suppressed during sex. Although the study is in the preliminary stages, it would appear that this gene keeps women sane.
As the gene, tentatively named Ooh la la, is present on the X-Chromosome men only ever have one copy of the gene, and thus have only half of the suppression factor.
Initial examination suggests that the suppression of the gene, which codes for serotonin uptake in the brain, helps keep mental balance.
"This gene is activated during sex," said Bonquers, "and it's effects last for several days. However, the longer that this gene goes without being activated, the more serotonin appears to be take up in the brain, eventually leading to erratic behaviour, and in susceptible individuals, the desire to buy cats."
Husbands all over the world are said to be rejoicing at this news, even though it has yet to be confirmed in a larger scale study involving more than five women.
"At last," said Arthur Tulip of Denbighshire, "I've got a reason to counter the not-in-the-mood excuse!"
Unfortunately for these men, Bonquers believes that it should be possible to create a pill that can be take orally once a week that mimics the effects. Cat breeders are said to be aghast at the news.
