A woman's sexual desires naturally fluctuate over the years. Highs and lows commonly coincide with the beginning or end of a relationship or with major life changes, such as pregnancy, menopause or illness. Some antidepressants and anti-seizure medications also can cause low sex drive in women.
If you have a persistent or recurrent lack of interest in sex that causes you personal distress, you may have hypoactive sexual desire disorder.
But you don't have to meet this medical definition to seek help. If you are bothered by a low sex drive or decreased sex drive, there are lifestyle changes and sex techniques that may put you in the mood more often. Some medications may offer promise as well.
