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. 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.
