Spontaneous triplets refer to the natural conception of three babies without the aid of fertility treatments. The odds of conceiving spontaneous triplets are rare, with estimates ranging from 1 in 8,100 to 1 in 1 million to 1 in 200 million. Spontaneous triplets are identical triplets that are naturally conceived. Triplets are rare, accounting for one in 9,000 births. In some cases, spontaneous triplets can pose a risk to the mother and babies, and doctors may closely monitor the pregnancy for complications such as twin-to-twin transfusion.
