In response to the recent growth in interest over unassisted childbirth, several national medical societies, including the Society of Obstetricians and Gynaecologists of Canada,[12] the American College of Obstetricians and Gynecologists,[10] and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists,[13] have issued strongly worded public statements warning against the practice. Professional midwives' associations, including the Royal College of Midwives[14] and the American College of Nurse-Midwives[3] also caution against UC.
