This specific group of symptoms (defined in DSM IV) that affects 3-5% of women and occurs during most menstrual cycles, it is separate from the more common PMS[1].

50-80% of mothers experience this transient period of mild depression, mood instability, anxiety following birth that can last up to 10 days post partum[1].

10% of mothers develop post partum depression, where symptoms of major depressive episode that occur within 4 weeks of birth, lasting 2-6 months. These may be augmented by negative social factors, stressful life events[1]. Screening tools such as the Edinburgh Postpartum Depression Scale[5] can be helpful in practice. There is new evidence that men can also suffer from post partum depression, a recent study showed that this occured in 2-4 % of men[4].

Depression may occur in women following other reproductive health problems such as infertility, hysterectomy, urinary incontinence, urogenital disorders[3].
