      In macaques, baboons and chimpanzees, dystocia because of breech birth is the commonest category of fetal death. [] Breech dystocia is rarely a problem for mother or neonates in small, multitocus species like marmosets and tamarins.
    • 2006, Richard Aghababian, Essentials of Emergency Medicine[1], page 480:
      Dystocia is defined as difficult delivery. Pelvic dystocia is due to aberrations of the pelvic architecture and its relationship to the presenting fetal part. [] Fetal dystocia may be due to excessive fetal size from gestational diabetes or congenital anomalies.
    • 2008, Dan Rice, The Complete Book of Dog Breeding, 2nd Edition, page 96:
      Although fetal dystocias are sometimes relieved by manipulation and instrumentation, cesarean sections are often the only practical methods of treatment.
    • 2009, James A. O′Leary, Shoulder Dystocia and Birth Injury: Prevention and Treatment, page 102:
      It is an appropriate way to allow resolution of the dystocia, after clearing the airway and checking for a nuchal cord.
      The prevailing thinking is that the time window in which to resolve a shoulder dystocia before asphyxial insult (not injury) is about 4 minutes.
