Natural triplet pregnancies are a random occurrence, according to the Utah Department of Health. There is no known way to purposely conceive triplets naturally. While assisted reproduction and fertility medications increase the chance of multiples, they are also no guarantee of triplets.Know More
Some women have a higher risk of conceiving multiples, reports the March of Dimes. Women who are over 30, obese, taller than average or have a family history of multiples are more likely to conceive multiples, including triplets.
Natural triplet pregnancies are rare, occurring in approximately one in 10,000 pregnancies, according to the American Society of Reproductive Medicine. Triplets occur in several ways. The most rare type are identical triplets, which results from a single fertilized egg that splits into two and then three. Another type of triplets results when two eggs are released and fertilized, and one splits into identical twins. The final type results when three separate eggs are released and fertilized.
A triplet birth is difficult and complications are common, according to the University of Rochester Medical Center. Women expecting triplets have increased risk of preterm labor, miscarriage, hypertension, anemia and abnormal amniotic fluid levels. Triplets are more likely to have birth defects. A risk with identicals who share a placenta is twin-to-twin transfusion syndrome, a life-threatening condition in which blood passes from one baby to the other through the placenta. Most sets of triplets are delivered via cesarean section.
