AB The  incidence  of  multiple  gestations  has  risen  significantly  over  several  decades,  primarily  due  to  increased  use  of  fertility  drugs  for  ovulation  induction,  superovulation,  and  assisted  reproductive  technologies  (ART),  such  as  in  vitro  fertilization  (IVF).Compared  with  singleton  pregnancies,  twin  pregnancies  are  more  likely  to  be  complicated  by  hypertensive  disorders,  gestational  diabetes  mellitus,  anemia,  preterm  birth,  ante-  and  postpartum  hemorrhage,  and  maternal  death.The  perinatal  mortality  rate  of  twins  is  3–4  times  higher—and  for  triplets  much  higher  still—than  in  singleton  pregnancies  as  a  result  of  chromosomal  abnormalities,  prematurity,  structural  anomalies,  hypoxia,  and  trauma.This  is  particularly  true  of  monozygotic  twins,  which  are  also  uniquely  susceptible  to  twin–twin  transfusion  syndrome.
