Many physical and psychological factors may contribute to low sex drive. Firstly, it is natural for your libido to fluctuate as you go through life, sometimes higher than usual and other times lower than usual. For women, these changes can be due to physical changes like pregnancy or menopause or psychological changes like stress or anxiety. In addition, some illnesses and medications can cause reduced libido. If a lowered sex drive becomes a source of mental distress, you may have Hypoactive Sexual Desire Disorder (HSDD), which a doctor can treat with prescription medications.Warnock J. J. (2002).
