'No nookie tonight, honey. I have a headache!'
It's one of the oldest excuses in the book for avoiding sex with your partner, but now researchers think that women who suffer from frequent headaches or migraines might in fact suffer sexual dysfunction.
In a study conducted in Italy, it was found that more than 90 percent of those women seeking medical advice for headaches also suffered from problems sexually. Of these, only 29 percent were actually concerned about it.
Of those problems suffered, women reported pain during sex and low libido amongst others.
Researchers from the University of Pavia, Italy, assessed the sexual health of a group of 100 women with an average age of 40 who reported suffering mild to severe headaches for years.
Along with neurological examinations and physical assessments, scientists gave the women questionnaires about their sex lives.
Researchers believe that while their study focused on headaches as a determinant of low sexual function, any type of chronic pain could be easily cited as a libido killer.
Those suffering from headaches also typically suffer anxiety and depression disorders and if they took medication, it might also play a part in reducing sexual drive.
The results of the questionnaire showed that 91 percent of the women suffered from serious sexual dysfunction, and 20 percent suffered from hypoactive sexual desire disorder in which sufferers feel little or no desire that causes them distress.
Women who suffered chronic headaches were more likely to be most concerned about the state of their sex lives.
Scientists concluded that more research into the sexual functioning of female headache sufferers was needed in order to establish whether the link to headaches and sexual dysfunction is widespread.
