Taking the contraceptive pill can reduce a woman’s sex drive, according to a new study by researchers in Germany.
Dr Lisa Maria Wallwiener and her team at the University of Heidelberg discovered a link between female sexual dysfunction and hormonal contraception.
Their findings support anecdotal evidence that the pill leads to flagging libido.
Over 1,000 women were examined as part of the study, the vast majority of whom had been sexually active in the last month.
Women on the pill were found to have lower levels of desire and arousal than those using non-hormonal methods of contraception.
The scientists explained that the hormones which halt ovulation also lower testosterone levels, which is fundamental to both make and female libido.
Those using barrier methods had the highest scores for sexual function.
Dr Wallwiener said female sexual dysfunction is a common disorder which affects around two in five women at some point in their lives.
The findings come after Pfizer, the company behind Viagra, said it was experimenting with a prototype drug that could boost sexual arousal in women.
