Causes of breech presentation are:a) Hydrocephalusb) Oligohydramniosc) Pelvic contracture d) Placenta praevia

At 28 weeks of pregnancy, approximately 20% of women have breech presentation. The fetus undergoes spontaneous version usually between 30th and 34th week. This corrects the breech position such that, at term only 3% of pregnant women have breech presentation. Any maternal or fetal condition, which prevents this spontaneous version will result in a persistent breech presentation.
